 +You have many files with similar names that you want to rename at one time.
 +
 +===Files starting with numbers===
 +You have files like “01 something” and “02 something else” etc and you want to remove the numbers in front of each of the file names; meaning you want ”something” instead of “01 something”, etc.  Here's what you do.
 +
 +  - Go into Terminal.
 +  - Go to the directory with the files: ''cd directory''
 +  - Type command: ''for file in [0-9][0-9]\ *; mv ”$file” ”${file:3}”; done''
 +The file:3 means skip the first 3 characters.
 +
 +===Files with word(s) to remove or replace===
 +Suppose you have files named like “my music song 1”, “his music orchestral 13”, “our music guitar solo” and you want to remove the word ”music” from them (so you would end up with “my song 1”, “his orchestral 13”, etc.  You use Finder for this.
 +
 +  - Open the directory holding the files in Finder.
 +  - Select the files you want to rename.
 +  - Right-click and choose ''Rename''.
 +  - In the dialog, choose ''Replace Text''
 +  - Find: put the text you want to remove or replace (e.g., ''music'')
 +  - Replace with: leave as blank to remove the text (or put the text you want to replace it with)
 +  - Click ''Rename''
 +
 +The file names will be changed.
