Remove all spaces or unwanted characters from the file name

Often, there are multiple spaces or unwanted characters in the file name, and it becomes annoying to access these files from the terminal. We can remove spaces from file name manually, but it becomes a tedious task when there are a large number of files involved. Fortunately, GNU/Linux has a command that solves this problem. This is the “rename” command, Which renames the filenames supplied according to the rule specified as the first argument. Let us understand this with a simple example.

Shown below are the files whose names contain spaces:

[email protected]:~/Downloads/techpulsetoday$ rename 's/ //g' *.mp3

It’s that simple, We are done. Now, Let us verify the results:

[email protected]:~/Downloads/techpulsetoday$ rename 's/ //g' *.mp3
[email protected]:~/Downloads/techpulsetoday$ ls -lash

Remove all spaces or unwanted characters from the file name

Indeed, it has worked. In the above example, the “rename” command specified the rule to replace the space with nothing, i.e., it just removes the space. In the above command, the “g” option implies “global”, i.e., “remove all spaces“. If you want to replace spaces with any other character   for instance, an underscore _ then use the following rule with the “rename” command:

[email protected]:~/Downloads/techpulsetoday$ rename 's/ /-/g' *.mp3

It’s that simple, We are done. Now,

[email protected]:~/Downloads/techpulsetoday$ rename 's/ /-/g' *.mp3
