Space to Underscore - Shell script

space_to_underscore.sh is a safe solution to recursively replace spaces with underscores (or vice versa) in file and directory names, starting from the current directory and to any subdirectories.

Recursively - operating on a directory and its contents, including the contents of any subdirectories.

Example

Before:

tree
.
|-- a dir
|   `-- file with spaces.txt
`-- b dir
    |-- another file with spaces.txt
    `-- yet another file with spaces.pdf

After:

tree
.
|-- a_dir
|   `-- file_with_spaces.txt
`-- b_dir
    |-- another_file_with_spaces.txt
    `-- yet_another_file_with_spaces.pdf

Usage

Note! To recursively replace underscores with spaces instead of spaces with underscores, follow the same steps, but using the underscore_to_space.sh file instead of space_to_underscore.sh.

1. Before you run the script, you must set the script executable permission. This is done only once, before the very first run of the script.

chmod +x space_to_underscore.sh

2. Go to the directory where you want to rename files and directories recursively (starting from the current directory and to any subdirectories).

cd /home/user/example

3. Run the space_to_underscore.sh.

~/space_to_underscore.sh

Note! In the example above, the space_to_underscore.sh file is located in the user home directory (~/). Change it according to the location of the file in your case.
