How to replace spaces in file names using a bash script, rename is part of util-linux. You need to descend depth first, because a whitespace filename can be part of a whitespace directory: find /tmp  You can remove spaces, replace spaces with underscore, uppercase/lowercase filename, add a prefix/suffix, remove/replace strings and also catalog files by adding an incremental number to the file name.

For example: $ tree . |-- a dir | `-- file with spaces.txt `-- b dir |-- another file with spaces.txt `-- yet another file with spaces.pdf becomes:

What if you want to apply the replace task recursively? How would you do that?

Well, I just found the answer myself. Not the most elegant solution, (also tries to rename files that do not comply with the condition) but it works. (BTW, in my case I needed to rename the files with '%20', not with an underscore)

#!/bin/bash
find . -type d | while read N
do
     (
           cd "$N"
           if test "$?" = "0"
           then

  • This didn't work for me. It claimed identical files existed (with the wrong filenames). E.g. trying to rename 1 - foo.jpg and my folder already had 1.jpg in it.
  • I find backticks bit hard to read when they are near quotes. The same but more readable would be for file in *; do mv "$file" $(echo $file | tr ' ' '_') ; done
  • Note: This is run from WITHIN the directory whose files' names you want to update. Alternatively, you can change * to PATH_TO_YOUR_DIRECTORY.
  • this will work if you have the perl-style rename and not the simpler redhat/fedora one
  • the fedora version would be rename " " "_" *
  • rename not available in OSX it appears.
  • On macOS 10.12.3, rename is available.
  • For some reason rename does not do a single thing on my CentOS box. Either with regex or not.
  • when i tried, i got mv: when moving multiple files, last argument must be a directory Try mv --help' for more information. mv: when moving multiple files, last argument must be a directory Try mv --help' for more information.
  • Again error mv: missing file argument Try mv --help' for more information. mv: missing file argument Try mv --help' for more information. mv: missing file argument Try mv --help' for more information. mv: missing file argument Try mv --help' for more information.
