What flags can one use with pacman -S to show only those packages, that aren't yet installed?
Will accept shell script if it can't be done by design. Thx.

After first try was the inverse answer, thanks Jeff Schaller. Here's a little script that filters out installed packages and only displays not installed packages.
#!/bin/sh installed=$(pacman -Q | cut -d ' ' -f 1 | tr '\n' '|') pacman -Ssq | egrep -v \'${installed}\'

- PLUS: Use
pacman -Ssq | egrep -v \'${installed}\' | egrep -i '<YOUR_PACKAGE_NAME_OR_PART>'to search only among uninstalled packages. NOTE:qflag excludes description.

pacman -Ssq | grep -E -v \'${installed}\'- and to search you just add it to the first part, no additional piping needed:pacman -Ssq pkgname | grep -E -v \'${installed}\'(after setting the installed variable). To pass this on to pacman for installation, you to add another pipe:pacman -Ssq xfce4 | grep -E -v \'${installed}\' | pacman -S -EkriirkE– EkriirkE2024-03-29 15:27:33 +00:00Commented Mar 29, 2024 at 15:27 - This can have false positives/negatives for example with the r package which will match against every package containing an r.
installed="|^"$(pacman -Q | cut -d ' ' -f 1 | tr '\n' '*' | sed 's/\*/$|^/g')seems to work for me.Maxwell Zhao– Maxwell Zhao2024-06-08 23:03:01 +00:00Commented Jun 8, 2024 at 23:03
here is a script with 3 different methods, all keeping the one line description. also it lets you do search terms with command line arguments
#!/bin/bash #pacman -Ss "$@" | pcregrep -Mv '.*\[installed.*\n' #pacman -Ss "$@" | sed -n -e '/\[installed/!p;: m' -e '//{' -e '$!{' -e 'n;b m' -e '}' -e'}' pacman -Ss "$@" | awk '/\[installed/ { getline; next } 1' example:
pacman-search-exclude-installed.sh search terms my research:
How to grep -v and also exclude the next line after the match?
How to `grep -v` and also exclude 'n' lines after the match?
expanding on @thomas answer here are some ready to go functions you can source and use to achieve OPs question
pmig () { pacman -Q | grep $1 | cut -d ' ' -f 1 } pmrg () { pacman -Ssq | grep $1 } pmnig () { local installed="|$(pmig $1 | tr '\n' '|')" pmrg $1 | grep -E -v \'${installed}\' } pmnigv () { pacman -Ss $1 | grep -v "$(pacman -Ss $1 | grep "\[installed\]" -A1 )" | grep -v "\[installed\]" } then trying out.
echo "==installed =="; pmig disk; echo "==in repos=="; pmrg disk; echo "===in repos but not installed==="; pmnig disk
results in
