I write simple script that allow use regex: #!/bin/sh regex=$(echo "$1" | sed -e 's|\\|&&|g' -e 's|=|\\=|g') for file in /etc/setup/*.lst.gz; do name=${file#/etc/setup/} name=${name%.lst.gz} gzip -d -c $file | sed -n "\=$regex={s=^=$name: /=;p;}" done But this script is extremely slow: $ time ./cygsearch.sh 'bin/emacs' emacs: /usr/bin/emacs-nox.exe emacs: /usr/bin/emacs.ico emacs: /usr/bin/emacsclient.exe emacs-X11: /usr/bin/emacs-X11.exe real 0m38.797s user 0m44.620s sys 0m25.574s
