Bash: move and rename files to parent directory

Question

I have the following working code:

for f in */*/*.jpg; do rename 's#/picture#p#' "$f"; done &&
for f in */*.jpg; do rename 's#/subfolder#s#' "$f"; done

However, this does not work with the following verison of rename: https://linux.die.net/man/1/rename

The following folder structure:

folder1/subfolder1/picture1.png
folder1/subfolder2/picture1.png
folder1/subfolder2/picture2.png
folder2/subfolder1/picture1.png

should be converted into the following structure

f1s1p1.png
f1s2p1.png
f1s2p2.png
f2s1p1.png

Answer 1

Check out the man page for rename that you linked yourself: the command takes two strings "from" and "to" (plus a list of files).

Synopsis

rename from to file...

You could just try the following:

for f in */*.jpg */*/*.jpg; do mv "$f" "$(echo $f | sed 's/\([a-zA-Z]\)[^0-9]*\([0-9][0-9]*\)/\1\2/g' | tr -d /)"; done

This will, however, leave the original folders in place which you will then have to remove manually.
