[SOLVED] pacman show dependency list

silenc3r · 2010-05-21 19:10:20

How can I make pacman show all dependencies of some package?

By checking man pacman.

Or finding "show dependencies" here.

silenc3r · 2010-05-21 19:29:48

I know about pacman -Qi/Si but I was wondering if there's some way to show only simple list of dependencies not whole package info.

hidefromkgb · 2010-05-21 19:40:41

Maybe not a very graceful solution, but still working

pacman -Qi pidgin|grep <STRING_THAT_MEANS_"DEPENDS_ON"_IN_YOUR_NATIVE_LANGUAGE>|cut -d: -f2

silenc3r · 2010-05-21 19:54:29

thanks a lot hidefromkgb, that is exactly what I was looking for

tesjo · 2010-05-21 20:12:20

Careful, that fails for when depends extend to multiple lines.

This will do it but it a sloppy way I think

pacman -Si pidgin|sed -n '/Depends\ On/,/:/p'|sed '$d'|cut -d: -f2

Here is a little command I wrote a while back while I was learning sed. It gives a bulk output of all your programs, their dependencies and optional dependencies. I ran into the "fails for when depends extend to multiple lines" issue and this should fix that. I haven't tested it very much so you be the judge.

 pacman -Qi | sed '/^Depends On/,/^Required By/{ s/^Required By.*$//; H; d }; /^Name/!d; /^Name/{ n;x;}'| sed '/^$/s//==================================================================================/'

Small Example Output: (looks much cleaner in the Terminal)

==================================================================================

Version : 1.7.6-3
Depends On : hal>=0.5.14 libgl libxfont>=1.4.1 openssl>=1.0.0

Optional Deps : None
==================================================================================
Name : xorg-utils
Version : 1.7.0-1
Depends On : None

==================================================================================

I added the equal signs for looks and to fit my default Terminal window. Just add or subtract them in the command to fit yours or to get rid of them just drop off the last section of the pipe.

Good Luck!:D

There are yet another two ways. Awk dependent, and Bash only.

Awk dependent:

#!/bin/bash
packageName="gstreamer0.10-bad-plugins"
depsList="$( pacman -Si "${packageName}" 2>/dev/null )"
depsList="$( \
        awk \
            -F ": " \
            -v searchToken="Depends On     " \
            ' \
               $0 ~ searchToken \
                { \
                    gsub(/[>=<]*[0-9.\-]* /," ",$2) ; \
                    gsub(/ +/,"\n",$2) ; \
                    print $2 ; \
                } \
            ' <<< "${depsList}" \
    )" 
echo "====  ${packageName}" | sort -u
echo "${depsList}"
unset depsList

Bash only:

#/bin/bash
packageName="gstreamer0.10-bad-plugins"
searchToken="Depends On     : "
depsList="$( pacman -Si "${packageName}" 2>/dev/null )"
shopt -s extglob
depsList="${depsList/*${searchToken}/}"
depsList="${depsList/$'\n'*/}"
depsList="${depsList//+([>=<])+([0-9.\-])*([[:space:]])/ }"
depsList="${depsList/#+([[:space:]])/}"
depsList="${depsList/%+([[:space:]])/}"
depsList="${depsList//+([[:space:]])/$'\n'}"
echo "====  ${packageName}"
echo "${depsList}" | sort -u
unset depsList

Save them it files s1 and s2, try

time ./s1 1>/dev/null ; time ./s2 1>/dev/null

3x difference in time consumption. Regular expressions is a hard weight.

With pactree it is possible to search recursively for ALL the dependencies of a package:

pactree -u PACKAGE

To search for reverse dependencies:

pactree -r PACKAGE

kozaki · 2014-11-27 15:44:10

Someone willing to help a noob using harryNID's pacman|sed commandline with an example?
Or Stack's small regex script. As it returns just the package name in this location :}

Note: When I get it works, it'd be cool with added prompt/input, eg:

#!/bin/bash                                                                        
read -p "Package Name please : " PACKAGE
packageName="$PACKAGE"
depsList="$( pacman -Si "${packageName}" 2>/dev/null )"
depsList="$( \
        awk \
            -F ": " \
            -v searchToken="Depends On     " \
            ' \
               $0 ~ searchToken \
                { \
                    gsub(/[>=<]*[0-9.\-]* /," ",$2) ; \
                    gsub(/ +/,"\n",$2) ; \
                    print $2 ; \
                } \
            ' <<< "${depsList}" \
    )"
echo "====  ${packageName}" | sort -u
echo "${depsList}"
unset depsList

This post is old. Real old. These days, there's expac.

$ expac -S '%r/%n: %D' pacman
falconindy/pacman: bash>=4.2.042-2  glibc>=2.17-2  libarchive>=3.1.2  curl>=7.19.4  gpgme  pacman-mirrorlist  archlinux-keyring
core/pacman: bash>=4.2.042-2  glibc>=2.17-2  libarchive>=3.1.2  curl>=7.19.4  gpgme  pacman-mirrorlist  archlinux-keyring

kozaki · 2014-11-27 19:55:51

Thank you for the update falconindy
Now I can use expac in case of conflicting update.
pacman -Qii shines in this field, though

I don't know what you mean by this, but I suspect you'd benefit from sklimming expac's manpage.

CentaurFire · 2015-08-10 22:53:18

pacman -Qii app_name

This will list Optional dependencies (along with other information but it's easy enough to scroll through)
