having this command:

$ find / -path /home/oldroot -prune -o -name config.yml -exec sed -i'' '/(swipe)|(pinch)/s/[0-9].*/1/' {} \+

won't edit:

couldn't open temporary file /home/shepherd/.config/fusuma/sedSQVSZd: Permission denied

You can say, it does not work because of sudo. But it does not even work with sudo, the point is the -i flag here. find found file /fusuma/config.yml, but -i change it into /fusuma/sedSQVSZd as sideeffect of in-place edditing. So is there a way to persist filenames with sed?

    The issue is in creating the temporary file that sed writes the result of the edits into before replacing the original file (this is how "in-place" editing works). The user running sed does not have permission to create the temporary file in that location. Can you show the permissions and ownerships on /home/shepherd/.config/fusuma, /home/shepherd/.config, /home/shepherd and /home and let us know what user is executing that command? – Kusalananda May 16 '20 at 23:06
  • all of them are own by me, except of /home/, which is as usual owned by root. The command is run by sudo privileges – Herdsman May 16 '20 at 23:25
  • but I am not sure these information are needed for clarification of sed command – Herdsman May 16 '20 at 23:34

    The issue is not changing the name of the temporary file to replace the original. The issue is creating the temporary file in the first place. – Kusalananda May 17 '20 at 11:16

    If you think that it's the pipe causing problem, did you try running that sed command without the pipe on the file directly? sed -i'' '/(swipe)|(pinch)/s/[0-9].*/1/' /home/shepherd/.config/fusuma/config.yml – Kusalananda May 17 '20 at 16:23
