How do I rename the extension for a batch of files

Question

In a directory, I have a bunch of *.html files.

I'd like to rename them all to *.txt

I use the bash shell.

Answer 1

Here is what i used to rename .edge files to .blade.php

for file in *.edge; do     mv "$file" "$(basename "$file" .edge).blade.php"; done

Works like charm.

Answer 2

If using bash, there's no need for external commands like sed, basename, rename, expr, etc.

for file in *.html
do
  mv "$file" "${file%.html}.txt"
done

Answer 3

If you prefer PERL, there is a short PERL script (orignally written by Larry Wall, the creator of PERL) that will do exactly what you want here: tips.webdesign10.com/files/rename.pl.txt. For your example the following should do the trick

rename.pl 's/html/txt/' *.html

Answer 4

Try this

rename .html .txt *.html 

usage:

rename [find] [replace_with] [criteria]

Answer 5

This question explicitly mentions Bash, but if you happen to have ZSH available it is pretty simple:

zmv '(*).*' '$1.txt'

If you get zsh: command not found: zmv then simply run:

autoload -U zmv

And then try again.

Thanks to this original article for the tip about zmv.
