I have a problem where I need to rename just certain files after the parent folder and afterwards move these to a central folder. Is there a way to do this? I would like to run this on a Synology NAS.

Root |-Subf1 | |-File.txt | |-File.doc | |-Subf1subf1 | | |-File.xml | | |-File.xls | |-Subf1subf2 | | |-File.pptx | | |-File.docx | |-Subf2 | |-File.txt | |-File.doc | |-Subf2subf1 | | |-File.xml | | |-File.xls

Result should be:

Root |-Subf1 | |-Subf1.txt | |-Subf1.doc | |-Subf1.xml | |-Subf1.xls | |-Subf1.pptx | |-Subf1.docx | |-Subf2 | |-Subf2.txt | |-Subf2.doc | |-Subf2.xml | |-Subf2.xls

There is no problem with overwriting files as they all have different extensions.

#! /bin/bash shopt -s globstar #enabled for '**' to match all files &directories recursively #shopt -s dotglob #uncomment to enable to match on hidden files/directories too cd /path/to/directory/Root for pathname in ./**/*; do [[ -f "$pathname" ]] && echo mv -v -- "$pathname" "${pathname%%/*}/${pathname%%/*}.${pathname##*.}"; done ##then remove remained empty directories for pathname in ./**/*; do [[ -d "$pathname" && -z "$(ls -A -- "$pathname")" ]] && rm -r -- "$pathname"; done
  • [[ -f "$pathname" ]] checks if the $pathname is a file
  • ${pathname%%/*}: Using shell-parameter-expansion, cut the longest suffix from the pathname parameter. cuts everything up-to first slash / character.
  • ${pathname##*.}": same, but this cuts the longest prefix from the pathname parameter; cuts everything up-to last dot . character.
  • [[ -d "$pathname" ]] checks if the $pathname is a directory
  • ... && -z "$(ls -A -- "$pathname")" then checks if basename of the pathname which was a directory, is empty or not.

remove echo when you were happy with the result.

POSIXly:

cd Root && LC_ALL=C find . \ -name '.?*' -prune -o \ -path './*/*/*' \ -prune \ -name '*.*' \ -type f \ -exec sh -c ' ret=0 for file do ext=${file##*.} sub=${file%/*/*} subname=${sub##*/} echo mv -i "$file" "$sub/$subname.$ext" || ret=$? done exit "$ret"' {} +

(remove echo if happy)

Empty dirs can be removed afterwards with:

find . -depth -type d -exec rmdir {} + 2> /dev/null

Or if your find supports the non-standard -empty and -delete:

find . -type d -empty -delete

(-delete implies -depth).
