Ubuntu – Shell script to move all files from subfolders to parent folder

Seems like the main trick here is translating the file name into the target folder name. There are two steps: truncate all but the first three digits, and remove zero padding. For this I have selected the sed and $((10# commands respectively:

for X in *; do mv $X $((10#$(echo $X | sed -e 's/^\(...\).*/\1/') )); done

This gives me minor errors such as mv: cannot move ‘114’ to a subdirectory of itself, ‘114/114’, but presumably you will not care about that if your files are getting moved where you want them to go.

You can use:

find test/*/* -type d | xargs -n1  sh -c 'echo mv -b ${0}/* "$( dirname ${0})" ";" rm -rvf ${0} '

It will just print Output on screen as below :

mv -b test/1/B/file1 test/1/B/file2 test/1/B/file3 test/1 ; rm -rvf test/1/B
mv -b test/1/C/file1 test/1/C/file2 test/1/C/file3 test/1 ; rm -rvf test/1/C
mv -b test/2/B/file1 test/2/B/file2 test/2/B/file3 test/2 ; rm -rvf test/2/B
mv -b test/2/C/file1 test/2/C/file2 test/2/C/file3 test/2 ; rm -rvf test/2/C
mv -b test/3/B/file1 test/3/B/file2 test/3/B/file3 test/3 ; rm -rvf test/3/B
mv -b test/3/C/file1 test/3/C/file2 test/3/C/file3 test/3 ; rm -rvf test/3/C
mv -b test/4/B/file1 test/4/B/file2 test/4/B/file3 test/4 ; rm -rvf test/4/B
mv -b test/4/C/file1 test/4/C/file2 test/4/C/file3 test/4 ; rm -rvf test/4/C
mv -b test/5/B/file1 test/5/B/file2 test/5/B/file3 test/5 ; rm -rvf test/5/B
mv -b test/5/C/file1 test/5/C/file2 test/5/C/file3 test/5 ; rm -rvf test/5/C

If output looks OK then you can simply append | sh at the end of that command, then it will run command which is shows in output.
