May 18, 2020 at 19:17 comment added Kusalananda @Herdsman You only get output with sed -n if you use the p command or the /p flag with the s command. Results of substitutions are not printed automatically (not with -n and not without -n). Also, you are clearly not running the commands that you show as the given command with locate would not replace 2 with 3 in the file that you show.

May 17, 2020 at 20:51 comment added Herdsman @Freddy that is not true, it suppresses pattern space, not any ouput, It should display matched substitution. So wihout -n it outputs every line, but the lines are not still substitued. This is not solution
May 17, 2020 at 20:47 comment added Freddy Remove the -n, it suppresses any output. And you don't need to escape | if you use -E.
May 17, 2020 at 20:44 comment added Herdsman still does not work: sudo find / -name config.yml -exec sed -En '/swipe\|pinch/s/[0-9]/3/' '{}' \+ . I will add -i once I would see it substitued correctly but for now, do not even substitued
May 17, 2020 at 20:40 comment added Freddy Change | to \| or add option -E, add option -i if you want to edit in-place, remove -n and you don't need to escape +.
May 17, 2020 at 20:34 comment added Herdsman from man sed: ` -n, --quiet, --silent suppress automatic printing of pattern space`
May 17, 2020 at 20:30 comment added fra-san Why is there a -n in your -exec-run sed?
