PACTREE(8) Pacman-contrib Manual PACTREE(8)

pactree - package dependency tree viewer

pactree [options] package

Pactree produces a dependency tree for a package.

By default, a tree-like output is generated, but with the --graph option, a Graphviz description is generated.

-a, --ascii
Use ASCII characters for tree formatting. By default, pactree will use Unicode line drawing characters if it is able to detect that the locale supports them.

-b, --dbpath

Specify an alternative database location.

-c, --color

Colorize output.

-d, --depth <num>

Limits the number of levels of dependency to show. A zero means show the named package only, one shows the packages that are directly required.

-g, --graph

Generate a Graphviz description. If this option is given, the --color and --linear options are ignored.

-h, --help

Output syntax and command-line options.

-l, --linear

Prints package names at the start of each line, one per line.

-r, --reverse

Show packages that depend on the named package.

-s, --sync

Read package data from sync databases instead of local database.

-u, --unique

List dependent packages once. Implies --linear.

-o, --optional[=DEPTH]

Additionally prints optional dependencies up to a certain depth, default 1 for immediate optional dependencies. When used in conjunction with -r it shows which packages it is optional for. In Graphviz mode, produce dotted lines. Negative values mean infinite depth.

--config <file>

Specify an alternate pacman configuration file.


Print log messages produced by libalpm.

--gpgdir <dir>

Specify an alternate GnuPG directory for verifying database signatures (default is /etc/pacman.d/gnupg).
