Script working on all files in various subdirectories

Question

Trying to execute script on files located into multiple subdirectories (with different depth). Im using script with arguments, Tried:

for i in "/home/working_dir_with_subdirs"/* ; do
     /opt/my_script -e -x "$i" "$i"/* "$i"/..
done

But only files in main directory /home/working_dir_with_subdirs was loaded by script. Files from subdirectories was not loaded, In terminal I saw that script is trying to execute subdirectory as a input file, not files inside directory.

Found some examples with find command, but files in subdirectories got different extensions.

Answer 1

One solution would use find and xargs:

find /home/working_dir_with_subdirs/ -type f -print0 |
  xargs -0 -n1 /opt/my_script -e -x

This would call /opt/my_script once for each file located in /home/working_dir_with_subdirs and its subdirectories.

If your script can accept multiple files as arguments, you could drop the -n1:

find /home/working_dir_with_subdirs/ -type f -print0 |
  xargs -0 /opt/my_script -e -x

This would call your script with multiple files as arguments, rather than once per file.

In both cases, the -print0 on find and the -0 on xargs are to correctly handle filenames that contain whitespace.
