Something like the script below and some examples of its use? $ cat find_best_header.sh #!/bin/bash # Show possible patch subject prefixes for a file in git # use commits that modify only the single file argument and # emit up to the 5 most common commit prefixes git log --no-merges --format='%h' -- $1 | while read commit ; do if [[ $(git log --format='%h' --name-only -1 $commit | wc -l) = 3 ]] ; then git log --format='%s' -1 $commit fi done | cut -f1 -d":" | cut -f1-3 -d" " | sort | uniq -c | sort -rn | head -5 $ ./find_best_header.sh drivers/ata/pata_icside.c 2 [ARM] pata_icside 1 Fix pata_icside build 1 [ARM] dma $ ./find_best_header.sh kernel/fork.c 36 fork 14 kernel/fork.c 6 mm 4 pidns 4 [PATCH] unshare system $ ./find_best_header.sh kernel/sched/core.c 150 sched 110 sched/core 12 sched/uclamp 12 sched/debug 10 sched/deadline $ ./find_best_header.sh drivers/iio/pressure/mpl115.c 3 iio
