Play The World's Biggest PAC-MAN game online or create your own PAC-MAN maze to make it even bigger. Made for Internet Explorer. Use your arrow keys to move PAC-MAN through the maze. Use exits to enter adjoining mazes at any time. When maze is complete, exit the maze to start a new one. Extra PAC-MAN awarded every 10,000 points. Pacman History The first Pacman were called Pac man and were published by Tell Magazines (they introduced Pacman puzzles to the world a decade later). Since then Pacman aka Pac man have been a regular feature in every arcade arena in the US and also in xarcades arenas. Pac man also appears in Game magazine. Google Pacman To consider Pac-Man, a simple game would be a shamefulness. It's a social symbol, an image of a whole decade, just as an element that reclassified gaming itself. Proof of this can be discovered in its underlying achievement, yet additionally by the way that it keeps on being adored and esteemed by each new age of gamers.
pacman - package manager utilitypacman <operation> [options] [targets]Pacman is a package management utility that tracks installed packages on a Linux system. It features dependency support, package groups, install and uninstall scripts, and the ability to sync your local machine with a remote repository to automatically upgrade packages. Pacman packages are a zipped tar format.
Since version 3.0.0, pacman has been the front-end to libalpm(3), the “Arch Linux Package Management” library. This library allows alternative front-ends to be written (for instance, a GUI front-end).
Invoking pacman involves specifying an operation with any potential options and targets to operate on. A target is usually a package name, file name, URL, or a search string. Targets can be provided as command line arguments. Additionally, if stdin is not from a terminal and a single hyphen (-) is passed as an argument, targets will be read from stdin.
-D, --databaseOperate on the package database. This operation allows you to modify certain attributes of the installed packages in pacman’s database. It also allows you to check the databases for internal consistency. See Database Options below.
-Q, --query
Query the package database. This operation allows you to view installed packages and their files, as well as meta-information about individual packages (dependencies, conflicts, install date, build date, size). This can be run against the local package database or can be used on individual package files. In the first case, if no package names are provided in the command line, all installed packages will be queried. Additionally, various filters can be applied on the package list. See Query Options below.
-R, --remove
Pac-man
Remove package(s) from the system. Groups can also be specified to be removed, in which case every package in that group will be removed. Files belonging to the specified package will be deleted, and the database will be updated. Most configuration files will be saved with a .pacsave extension unless the --nosave option is used. See Remove Options below.
-S, --sync
Synchronize packages. Packages are installed directly from the remote repositories, including all dependencies required to run the packages. For example, pacman -S qt will download and install qt and all the packages it depends on. If a package name exists in more than one repository, the repository can be explicitly specified to clarify the package to install: pacman -S testing/qt. You can also specify version requirements: pacman -S 'bash>=3.2'. Quotes are needed, otherwise the shell interprets '>' as redirection to a file.
In addition to packages, groups can be specified as well. For example, if gnome is a defined package group, then pacman -S gnome will provide a prompt allowing you to select which packages to install from a numbered list. The package selection is specified using a space- and/or comma-separated list of package numbers. Sequential packages may be selected by specifying the first and last package numbers separated by a hyphen (-). Excluding packages is achieved by prefixing a number or range of numbers with a caret (^).
Packages that provide other packages are also handled. For example, pacman -S foo will first look for a foo package. If foo is not found, packages that provide the same functionality as foo will be searched for. If any package is found, it will be installed. A selection prompt is provided if multiple packages providing foo are found.
You can also use pacman -Su to upgrade all packages that are out-of-date. See Sync Options below. When upgrading, pacman performs version comparison to determine which packages need upgrading. This behavior operates as follows:
Additionally, version strings can have an epoch value defined that will overrule any version comparison, unless the epoch values are equal. This is specified in an epoch:version-rel format. For example, 2:1.0-1 is always greater than 1:3.6-1.
-T, --deptest
Check dependencies; this is useful in scripts such as makepkg to check installed packages. This operation will check each dependency specified and return a list of dependencies that are not currently satisfied on the system. This operation accepts no other options. Example usage: pacman -T qt 'bash>=3.2'.
-U, --upgrade
Upgrade or add package(s) to the system and install the required dependencies from sync repositories. Either a URL or file path can be specified. This is a “remove-then-add” process. See Upgrade Options below; also see Handling Config Files for an explanation on how pacman takes care of configuration files.
-F, --files
Query the files database. This operation allows you to look for packages owning certain files or display files owned by certain packages. Only packages that are part of your sync databases are searched. See File Options below.
-V, --version
-h, --help
Display syntax for the given operation. If no operation was supplied, then the general syntax is shown.
-b, --dbpath <path>
Specify an alternative database location (the default is /var/lib/pacman). This should not be used unless you know what you are doing. NOTE: If specified, this is an absolute path, and the root path is not automatically prepended.
-r, --root <path>
Specify an alternative installation root (default is /). This should not be used as a way to install software into /usr/local instead of /usr. NOTE: If database path or log file are not specified on either the command line or in pacman.conf(5), their default location will be inside this root path. NOTE: This option is not suitable for performing operations on a mounted guest system. See --sysroot instead.
-v, --verbose
Output paths such as the Root, Conf File, DB Path, Cache Dirs, etc.
--arch <arch>
--cachedir <dir>
Specify an alternative package cache location (the default is /var/cache/pacman/pkg). Multiple cache directories can be specified, and they are tried in the order they are passed to pacman. NOTE: This is an absolute path, and the root path is not automatically prepended.
--color <when>
Specify when to enable coloring. Valid options are always, never, or auto. always forces colors on; never forces colors off; and auto only automatically enables colors when outputting onto a tty.
--config <file>
--debug
Display debug messages. When reporting bugs, this option is recommended to be used.
--gpgdir <dir>
Specify a directory of files used by GnuPG to verify package signatures (the default is /etc/pacman.d/gnupg). This directory should contain two files: pubring.gpg and trustdb.gpg. pubring.gpg holds the public keys of all packagers. trustdb.gpg contains a so-called trust database, which specifies that the keys are authentic and trusted. NOTE: This is an absolute path, and the root path is not automatically prepended.
--hookdir <dir>
Specify a alternative directory containing hook files (the default is /etc/pacman.d/hooks). Multiple hook directories can be specified with hooks in later directories taking precedence over hooks in earlier directories. NOTE: This is an absolute path, and the root path is not automatically prepended.
--logfile <file>
Specify an alternate log file. This is an absolute path, regardless of the installation root setting.
--noconfirm
Bypass any and all “Are you sure?” messages. It’s not a good idea to do this unless you want to run pacman from a script.
--confirm
--disable-download-timeout
Disable defaults for low speed limit and timeout on downloads. Use this if you have issues downloading files with proxy and/or security gateway.
--sysroot <dir>
Specify an alternative system root. Pacman will chroot and chdir into the system root prior to running. This allows mounted guest systems to be properly operated on. Any other paths given will be interpreted as relative to the system root. Requires root privileges.
-d, --nodepsSkips dependency version checks. Package names are still checked. Normally, pacman will always check a package’s dependency fields to ensure that all dependencies are installed and there are no package conflicts in the system. Specify this option twice to skip all dependency checks.
--assume-installed <package=version>
Add a virtual package 'package' with version 'version' to the transaction to satisfy dependencies. This allows to disable specific dependency checks without affecting all dependency checks. To disable all dependency checking, see the --nodeps option.
--dbonly
Adds/removes the database entry only, leaving all files in place.
--noprogressbar
Do not show a progress bar when downloading files. This can be useful for scripts that call pacman and capture the output.
--noscriptlet
If an install scriptlet exists, do not execute it. Do not use this unless you know what you are doing.
-p, --print
Only print the targets instead of performing the actual operation (sync, remove or upgrade). Use --print-format to specify how targets are displayed. The default format string is '%l', which displays URLs with -S, file names with -U, and pkgname-pkgver with -R.
--print-format <format>
Specify a printf-like format to control the output of the --print operation. The possible attributes are: '%n' for pkgname, '%v' for pkgver, '%l' for location, '%r' for repository, and '%s' for size. Implies --print.
--asdepsInstall packages non-explicitly; in other words, fake their install reason to be installed as a dependency. This is useful for makepkg and other build-from-source tools that need to install dependencies before building the package.
--asexplicit
Install packages explicitly; in other words, fake their install reason to be explicitly installed. This is useful if you want to mark a dependency as explicitly installed so it will not be removed by the --recursive remove operation.
--ignore <package>
Directs pacman to ignore upgrades of package even if there is one available. Multiple packages can be specified by separating them with a comma.
--ignoregroup <group>
Directs pacman to ignore upgrades of all packages in group, even if there is one available. Multiple groups can be specified by separating them with a comma.
--needed
Do not reinstall the targets that are already up-to-date.
--overwrite <glob>
Bypass file conflict checks and overwrite conflicting files. If the package that is about to be installed contains files that are already installed and match glob, this option will cause all those files to be overwritten. Using --overwrite will not allow overwriting a directory with a file or installing packages with conflicting files and directories. Multiple patterns can be specified by separating them with a comma. May be specified multiple times. Patterns can be negated, such that files matching them will not be overwritten, by prefixing them with an exclamation mark. Subsequent matches will override previous ones. A leading literal exclamation mark or backslash needs to be escaped.
-c, --changelog-d, --deps
Restrict or filter output to packages installed as dependencies. This option can be combined with -t for listing real orphans - packages that were installed as dependencies but are no longer required by any installed package.
-e, --explicit
Restrict or filter output to explicitly installed packages. This option can be combined with -t to list explicitly installed packages that are not required by any other package.
-g, --groups
Display all packages that are members of a named group. If a name is not specified, list all grouped packages.
-i, --info
Display information on a given package. The -p option can be used if querying a package file instead of the local database. Passing two --info or -i flags will also display the list of backup files and their modification states.
-k, --check
Check that all files owned by the given package(s) are present on the system. If packages are not specified or filter flags are not provided, check all installed packages. Specifying this option twice will perform more detailed file checking (including permissions, file sizes, and modification times) for packages that contain the needed mtree file.
-l, --list
List all files owned by a given package. Multiple packages can be specified on the command line.
-m, --foreign
Restrict or filter output to packages that were not found in the sync database(s). Typically these are packages that were downloaded manually and installed with --upgrade.
-n, --native
Restrict or filter output to packages that are found in the sync database(s). This is the inverse filter of --foreign.
-o, --owns <file>
Search for packages that own the specified file(s). The path can be relative or absolute, and one or more files can be specified.
-p, --file
Signifies that the package supplied on the command line is a file and not an entry in the database. The file will be decompressed and queried. This is useful in combination with --info and --list.
-q, --quiet
Show less information for certain query operations. This is useful when pacman’s output is processed in a script. Search will only show package names and not version, group, and description information; owns will only show package names instead of 'file is owned by pkg' messages; group will only show package names and omit group names; list will only show files and omit package names; check will only show pairs of package names and missing files; a bare query will only show package names rather than names and versions.
-s, --search <regexp>
Search each locally-installed package for names or descriptions that match regexp. When including multiple search terms, only packages with descriptions matching ALL of those terms are returned.
-t, --unrequired
Restrict or filter output to print only packages neither required nor optionally required by any currently installed package. Specify this option twice to include packages which are optionally, but not directly, required by another package.
-u, --upgrades
Restrict or filter output to packages that are out-of-date on the local system. Only package versions are used to find outdated packages; replacements are not checked here. This option works best if the sync database is refreshed using -Sy.
-c, --cascadeRemove all target packages, as well as all packages that depend on one or more target packages. This operation is recursive and must be used with care, since it can remove many potentially needed packages.
-n, --nosave
Instructs pacman to ignore file backup designations. Normally, when a file is removed from the system, the database is checked to see if the file should be renamed with a .pacsave extension.
-s, --recursive
Remove each target specified including all of their dependencies, provided that (A) they are not required by other packages; and (B) they were not explicitly installed by the user. This operation is recursive and analogous to a backwards --sync operation, and it helps keep a clean system without orphans. If you want to omit condition (B), pass this option twice.
-u, --unneeded
Removes targets that are not required by any other packages. This is mostly useful when removing a group without using the -c option, to avoid breaking any dependencies.
-c, --cleanRemove packages that are no longer installed from the cache as well as currently unused sync databases to free up disk space. When pacman downloads packages, it saves them in a cache directory. In addition, databases are saved for every sync DB you download from and are not deleted even if they are removed from the configuration file pacman.conf(5). Use one
--clean switch to only remove packages that are no longer installed; use two to remove all files from the cache. In both cases, you will have a yes or no option to remove packages and/or unused downloaded databases.
If you use a network shared cache, see the CleanMethod option in pacman.conf(5).
-g, --groups
Display all the members for each package group specified. If no group names are provided, all groups will be listed; pass the flag twice to view all groups and their members.
-i, --info
Display information on a given sync database package. Passing two --info or -i flags will also display those packages in all repositories that depend on this package.
-l, --list
List all packages in the specified repositories. Multiple repositories can be specified on the command line.
-q, --quiet
Show less information for certain sync operations. This is useful when pacman’s output is processed in a script. Search will only show package names and not repository, version, group, and description information; list will only show package names and omit databases and versions; group will only show package names and omit group names.
-s, --search <regexp>
This will search each package in the sync databases for names or descriptions that match regexp. When you include multiple search terms, only packages with descriptions matching ALL of those terms will be returned.
-u, --sysupgrade
Upgrades all packages that are out-of-date. Each currently-installed package will be examined and upgraded if a newer package exists. A report of all packages to upgrade will be presented, and the operation will not proceed without user confirmation. Dependencies are automatically resolved at this level and will be installed/upgraded if necessary.
Pass this option twice to enable package downgrades; in this case, pacman will select sync packages whose versions do not match with the local versions. This can be useful when the user switches from a testing repository to a stable one.
Additional targets can also be specified manually, so that -Su foo will do a system upgrade and install/upgrade the 'foo' package in the same operation.
-w, --downloadonly
Retrieve all packages from the server, but do not install/upgrade anything.
-y, --refresh
Download a fresh copy of the master package database from the server(s) defined in pacman.conf(5). This should typically be used each time you use --sysupgrade or -u. Passing two --refresh or -y flags will force a refresh of all package databases, even if they appear to be up-to-date.
--asdeps <package>
Mark a package as non-explicitly installed; in other words, set their install reason to be installed as a dependency.
--asexplicit <package>
Mark a package as explicitly installed; in other words, set their install reason to be explicitly installed. This is useful if you want to keep a package installed even when it was initially installed as a dependency of another package.
-k, --check
Check the local package database is internally consistent. This will check all required files are present and that installed packages have the required dependencies, do not conflict and that multiple packages do not own the same file. Specifying this option twice will perform a check on the sync databases to ensure all specified dependencies are available.
-q, --quiet
Suppress messages on successful completion of database operations.
-y, --refreshGoogle Pac-man
Download fresh package databases from the server. Use twice to force a refresh even if databases are up to date.
-l, --list
-x, --regex
Pacman.com
Interpret each query as a regular expression.
-q, --quiet
Show less information for certain file operations. This is useful when pacman’s output is processed in a script, however, you may want to use --machinereadable instead.
--machinereadable
Print each match in a machine readable output format. The format is repository0pkgname0pkgver0pathn with 0 being the NULL character and n a linefeed.
Pacman uses the same logic as
rpm to determine action against files that are designated to be backed up. During an upgrade, three MD5 hashes are used for each backup file to determine the required action: one for the original file installed, one for the new file that is about to be installed, and one for the actual file existing on the file system. After comparing these three hashes, the following scenarios can result:
original=X, current=X, new=X
All three files are the same, so overwrites are not an issue. Install the new file.
Pac-man Game
original=X, current=X, new=Y
The current file is the same as the original, but the new one differs. Since the user did not ever modify the file, and the new one may contain improvements or bug fixes, install the new file.
original=X, current=Y, new=X
Both package versions contain the exact same file, but the one on the file system has been modified. Leave the current file in place.
original=X, current=Y, new=Y
The new file is identical to the current file. Install the new file.
original=X, current=Y, new=Z
All three files are different, so install the new file with a .pacnew extension and warn the user. The user must then manually merge any necessary changes into the original file.
original=NULL, current=Y, new=Z
The package was not previously installed, and the file already exists on the file system. Install the new file with a .pacnew extension and warn the user. The user must then manually merge any necessary changes into the original file.
