Linux - Replacing spaces in the file names

Question

I have a number of files in a folder, and I want to replace every space character in all file names with underscores. How can I achieve this?

Answer 1

The easiest way to replace a string (space character in your case) with another string in Linux is using sed. You can do it as follows

sed -i 's/\s/_/g' *

Hope this helps.
