Rename multiple files to another extension in Linux
Posted by Admin on August 12th, 2007
for old in *.php5; do cp $old `basename $old .php5`.php; done
Thats all there is to it. Let us say you need to rename index.php5 to index.php. The way above snippet works is that it loops through current directory and finds all the files with extension “.php5″ and processes ‘one by one. In our index.php5 file example, it finds index.php5 file, does a cp index.php5 `basename index.php5 .php5`.php <- basename returns “index” so you add .php to it and now you are left with index.php. Of course you can do mv command if you want to just move the file to new name.

You can also use the ‘rename’ command included with most debian installs. It’s a little more intuitive, imho.
$ rename
Usage: rename [-v] [-n] [-f] perlexpr [filenames]
$ rename ‘s/\.php5/.php/’ *.php5

And I’m using ‘mmv’

And this can be usede too:
#!/bin/bash
for x in *.php5; do n=${x/.php5/.php}; mv $x $n; done
And it’s can be used in other dir than ‘.’

The same can be done using the parameter expansion feature of the bash shell.
for a in *php5 ; do mv $a ${a%%5} ; done

Good job!

What all those commands do not cover is to add an extension to a file that has none.
How would that work?

Vincent,
for old in *; do mv $old `basename $old`.zip; done
* = all files, you can change that though. like FILE*

how would you keep the extension but append -xyz to the basename?
for example, i want to copy all files in dir a and append -xyz the end of the name while keeping the extension to dir b.
