How to rename a part of a file or files
 
hey everybody in LQ

I have a few video files with this name structure.

TV Show Season 1 - Ep 1 title.mp4
TV Show Season 1 - Ep 2 title.mp4
TV Show Season 1 - Ep 3 title.mp4
etc..

I want to change it to this

TV Show Season 1 - Ep 01 title.mp4
TV Show Season 1 - Ep 02 title.mp4
TV Show Season 1 - Ep 03 title.mp4

What is the solution? thank you folks

How many files are there? Renaming a few can be done by hand...

I have 20 files but I want to change the first 9 files. So far I have been doing it manually but it gets tedious after a while.

Create a for-in loop over all your *.mp4's
Replace the Ep 1 with Ep 01 etc.
Rename it.

In a file:
Code:
#!/bin/sh
for file in *.mp4; do
    renamedFile=$(echo $file | sed 's/Ep \([0-9]\)/Ep 0\1/')
    echo mv \"$file\" \"$renamedFile\" | sh
done
Or in one line from the Terminal:
Code:
for file in *.mp4; do echo mv \"$file\" \"$(echo $file | sed 's/Ep \([0-9]\)/Ep 0\1/')\" | sh; done

you're the man parnmatt, it looks like freakin' algebra but it did the job :)

You are most welcome.
Programming/Scripting kinda is a bit like maths.
