For example: perhaps use something like: $ grep -h '^\+\+\+ b/' <patch> | \ sed 's@^\+\+\+ b/@@' | sort | uniq | \ while read file ; do \ ./scripts/get_maintainer.pl --nogit --nogit-fallback --subsystem --status --separator , $file ; \ done or use parallel like: $ grep -h '^\+\+\+ b/' <patch> | \ sed 's@^\+\+\+ b/@@' | sort | uniq | \ parallel -k ./scripts/get_maintainer.pl --nogit --nogit-fallback --subsystem --status --separator , runtime on my system for this is Using while read loop: real 0m2.509s user 0m2.236s sys 0m0.296s Using parallel: real 0m1.340s user 0m4.159s sys 0m0.429s
