Anyone knows how to write a bash script that can rename all folders in a directory? It needs to delete the first words of all folders.

Currently it looks like this:

ABC DEF Folder1
ABC DEF Folder2
ABC DEF Folder3
ABC DEF Folder1000

Delete the identical letters


To achieve


I'm kinda new to linux and don't got a clue about bash scripting yet. Anyone who can provide hints/ solutions?

  • why use a script? why not just rename (with globbing) – guiverc Jan 23 '18 at 23:24
  • Because that's a shit tons of work for a huge amount of folders and I know a smarter solution is possible. I want to save some of the chars to be able to identify the folders by their name. – Sir hennihau Jan 23 '18 at 23:25
  • rename s/ABC\ DEF\ // * isn't a lot a work – guiverc Jan 23 '18 at 23:30
  • krename is a useful gui tool here, particularly if you have KDE. – pbhj Jan 24 '18 at 4:19

Quick Answer

I'd not bother with script ... just rename

rename s/ABC\ DEF\ // *

s/string1/string2/ causes it to search & replace string1 with string 2.

string 1 is made longer due spaces and need to escape them '\ ', string 2 being empty '//'

finally * forces it to work on all files/dirs in current directory

Read the man rename and it'll provide clues. The main page refererences ' perlexprs' (perl expressions; meaning more man pages) but they are a superset of POSIX ones meaning you have more power, but can just limit yourself to posix too.

For simple text matches such as this (which don't really require the power of regular expressions) there's also mmv e.g. given

$ ls -d */
ABC DEF Folder1/   ABC DEF Folder3/  ABC DEF Folder6/  ABC DEF Folder9/
ABC DEF Folder10/  ABC DEF Folder4/  ABC DEF Folder7/
ABC DEF Folder2/   ABC DEF Folder5/  ABC DEF Folder8/


mmv -r 'ABC DEF *' '#1'

results in

$ ls -d */
Folder1/   Folder2/  Folder4/  Folder6/  Folder8/
Folder10/  Folder3/  Folder5/  Folder7/  Folder9/

FWIW it's not actually much more work to script it in the (bash, or POSIX sh) shell -

for f in */; do mv -- "$f" "${f#ABC DEF }"; done
