How to remove all colons in file names:

To rename files in the current directory and all its subdirectories by removing colons from their filenames, you can use the following one-liner command:

find . -depth -name '*:*' -execdir bash -c 'mv "$1" "${1//:/}"' bash {} \;

Explanation

• find . -depth -name '*:*': This finds all files (including in subdirectories) that contain a colon in their name.
• -execdir: Executes the command in the directory where the file is located.
• bash -c 'mv "$1" "${1//:/}"' bash {} \;: This command runs mv to rename the file, removing colons from the filename.
