It has simple dependency support and the ability +to connect to a remote ftp server and automatically upgrade packages on +the local system. pacman package are \fIgzipped tar\fP format. +.SH OPERATIONS +.TP +.B "\-A, \-\-add" +Add a package to the system. Package will be uncompressed +into the installation root and the database will be updated. +.TP +.B "\-R, \-\-remove" +Remove a package from the system. Files belonging to the +specified package will be deleted, and the database will +be updated. Most configuration files will be saved with a +\fI.pacsave\fP extension unless the \fB--nosave\fP option was +used. +.TP +.B "\-U, \-\-upgrade" +Upgrade a package. This is essentially a "remove-then-add" +process. See \fBHANDLING CONFIG FILES\fP for an explanation +on how pacman takes care of config files. +.TP +.B "\-Q, \-\-query" +Query the package database. This operation allows you to +view installed packages and their files, as well as meta-info +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 .tar.gz packages. See +\fBQUERY OPTIONS\fP below. +.TP +.B "\-S, \-\-sync" +Synchronize packages. With this function you can install packages +directly from the ftp servers, complete with all dependencies required +to run the packages. For example, \fBpacman -S qt\fP will download +qt and all the packages it depends on and install them. You could also use +\fBpacman -Su\fP to upgrade all packages that are out of date (see below). +.TP +.B "\-V, \-\-version" +Display version and exit. +.TP +.B "\-h, \-\-help" +Display syntax for the given operation. If no operation was +supplied then the general syntax is shown. +.SH OPTIONS +.TP +.B "\-v, \-\-verbose" +Output more status and error messages. +.TP +.B "\-f, \-\-force" +Bypass file conflict checks,, overwriting conflicting files. If the +package that is about to be installed contains files that are already +installed, this option will cause all those files to be overwritten. +This option should be used with care, ideally not at all. +.TP +.B "\-d, \-\-nodeps" +Skips all dependency checks. 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. This +switch disables these checks. +.TP +.B "\-n, \-\-nosave" +(only used with \fB--remove\fP) +Instructs pacman to ignore file backup designations. Normally, when +a file is about to be \fIremoved\fP from the system the database is first +checked to see if the file should be renamed to a .pacsave extension. If +\fB--nosave\fP is used, these designations are ignored and the files are +removed. +.TP +.B "\-r, \-\-root <path>" +Specify alternative installation root (default is "/"). This +should \fInot\fP be used as a way to install software into +e.g. /usr/local instead of /usr. Instead this should be used +if you want to install a package on a temporary mounted partition, +which is "owned" by another system. By using this option you not only +specify where the software should be installed, but you also +specify which package database to use. +.SH SYNC OPTIONS +.TP +.B "\-y, \-\-refresh" +Download a fresh copy of the master package list from the ftp server +defined in \fI/etc/pacman.conf\fP. This should typically be used each +time you use \fB--sysupgrade\fP. +.TP +.B "\-u, \-\-sysupgrade" +Upgrades all packages that are out of date. pacman will examine every +package installed on the system, and if a newer package exists on the +server it will upgrade. pacman will present a report of all packages +it wants to upgrade and will not proceed without user confirmation. +Dependencies are automatically resolved at this level and will be +installed/upgraded if necessary. +.TP +.B "\-s, \-\-search <string>" +This will search each package in the package list for names or descriptions +that contains <string>. +.TP +.B "\-c, \-\-clean" +Remove packages from the cache. When pacman downloads packages, +it saves them in \fI/var/cache/pacman/pkg\fP. If you need to free up +diskspace, you can remove these packages by using the --clean option. +.SH QUERY OPTIONS +.TP +.B "\-o, \-\-owns <file>" +Search for the package that owns <file>. +.TP +.B "\-l, \-\-list" +List all files owned by <package>. Multiple packages can be specified on +the command line. +.TP +.B "\-i, \-\-info" +Display information on a given package. If it is used with the \fB-p\fP +option then the .PKGINFO file will be printed. +.TP +.B "\-p, \-\-file" +Tells pacman that the package supplied on the command line is a +file, not an entry in the database. Pacman will decompress the +file and query it. This is useful with \fB--info\fP and \fB--list\fP. +.SH HANDLING CONFIG FILES +pacman uses the same logic as rpm to determine action against files +that are designated to be backed up. During an upgrade, it uses 3 +md5 hashes for each backup file to determine the required action: +one for the original file installed, one for the new file that's about +to be installed, and one for the actual file existing on the filesystem. +After comparing these 3 hashes, the follow scenarios can result: +.TP +original=\fBX\fP, current=\fBX\fP, new=\fBX\fP +All three files are the same, so we win either way. Install the new file. +.TP +original=\fBX\fP, current=\fBX\fP, new=\fBY\fP +The current file is un-altered from the original but the new one is +different. Since the user did not ever modify the file, and the new +one may contain improvements/bugfixes, we install the new file. +.TP +original=\fBX\fP, current=\fBY\fP, new=\fBX\fP +Both package versions contain the exact same file, but the one +on the filesystem has been modified since. In this case, we leave +the current file in place. +.TP +original=\fBX\fP, current=\fBY\fP, new=\fBY\fP +The new one is identical to the current one. Win win. Install the new file. +.TP +original=\fBX\fP, current=\fBY\fP, new=\fBZ\fP +All three files are different. So we install the new file, but back up the +old one to a .pacsave extension. This way the user can move the old configuration +file back into place if he wishes. +.SH CONFIGURATION +pacman will attempt to read \fI/etc/pacman.conf\fP each time it is invoked. Currently +the only options in it are for the --sync operation, but more may be added later. +.TP +.B "Sync_Tree_Name" +Sets the name of the package set you wish to follow. The common choices are \fIcurrent\fP +and \fIstable\fP. You could also specify a specific package version, eg, 0.3. +.TP +.B "Sync_Server" +This is the hostname of the ftp server that will be used for downloading lists and +packages. eg, \fIftp.ibiblio.org\fP. +.TP +.B "Sync_Tree_Path" +This is the full path name (on the ftp server) to the package tree you are following. +So if you are following \fIcurrent\fP, on \fIftp.ibiblio.org\fP, you would use +\fI/pub/linux/distributions/archlinux/current\fP. +.SH SEE ALSO +\fBmakepkg\fP is the package-building tool that comes with pacman. +.SH AUTHOR +.nf +Judd Vinet <jvinet@zeroflux.org> +.fi |
