How to ignore "target not found" errors?

kaari · 2013-09-08 13:34:41

I'm running pacman from a script and it would be preferable if it didn't abort because of missing packages.
Is there a way of configuring pacman so that it installs everything it can first, and notifies the user about missing targets only at the very end? (assuming of course that the missing targets are not dependencies of other packages)

Maybe you can run a 'for' loop instead of 'pacman -Syu foo bar baz'.

Please post the exact command you're using.

Or, perhaps, for a simpler output, first run a `pacman -Ss pkgname` for each one in a for loop, and append only those that are found to a variable (ie $pkglist). Then `pacman -Syu $pkglist`.

This wouldn't be any quicker, but it would avoid errors, and it would allow the final installation to run in one shot.

*If* your list of packages are all _actual_ package names, (e.g. python-setuptools, NOT python-distribute which python-setuptools now provides), something like this will do:

pkgs=(foo bar baz)
pkgs_200=($(comm -12 <(pacman -Slq|sort -u) <(printf '%s\n' "${pkgs[@]}"|sort -u)))
pkgs_404=($(comm -23 <(printf '%s\n' "${pkgs[@]}"|sort -u) <(printf '%s\n' "${pkgs_200[@]}")))
pacman -S "${pkgs_200[@]}"
printf "404 Not Found:\n" >&2
printf "%s\n" "${pkgs_404[@]}" >&2

pacman -Sp pkgname might be easier to work with.

FWIW, I actually tried posting a feature request for this before:

Incorporating cookies' idea (-Sp), here is a proper version that should work with any package list; even more HTTP code abuse:

#!/bin/bash

declare -a pkgs pkgs_200 pkgs_202 pkgs_404
declare -A pkgs_301

pkgs=(foo bar baz)
pkgs=($(printf '%s\n' "${pkgs[@]}"|sort -u))
pkgs_200=($(comm -12 <(pacman -Slq|sort -u) <(printf '%s\n' "${pkgs[@]}")))
pkgs_202=($(comm -23 <(printf '%s\n' "${pkgs[@]}") <(printf '%s\n' "${pkgs_200[@]}")))
for pkg in "${pkgs_202[@]}"; do
  pkgname=$(pacman -Spdd --print-format %n "$pkg" 2> /dev/null)
  if [[ -n $pkgname ]]; then
    pkgs_301[$pkg]=$pkgname
  else
    pkgs_404+=("$pkg")
  fi
done

pacman -S "${pkgs_200[@]}" "${pkgs_301[@]}"
printf "\n301 Moved Permanently:\n" >&2
paste -d : <(printf "%s\n" "${!pkgs_301[@]}") <(printf "%s\n" "${pkgs_301[@]}") >&2
printf "\n404 Not Found:\n" >&2
printf "%s\n" "${pkgs_404[@]}" >&2

Edit: use `pacman -Spdd` to prevent listing of dependencies.

This is what I did:

for P in $( </tmp/package-list-one-per-line )
do
    if ! (pacman -Q | grep ${P} > /dev/null)
    then
        pacman -S ${P} --noconfirm
    fi
done
