Bash - renaming multiple file extensions

Question

I've just very recently switched to Linux and I want to change a load of files to have different extensions. For example I want to change .doc/docx to .txt and images to .jpg and so on. Is there a csh script that would cover any extension or would I have to write a new one for each filetype.

I have this so far, but I'm not sure if it will actually work. Any help is much appreciated!

#!/bin/bash
for f in *.$1
do
    [ -f "$f" ] && mv -v "$f" "${f%$1}$2"
done

rename .doc .txt *.doc

Answer 2

You need proper programs to convert file format:

• Use wvWare to convert doc to html
• Use ImageMagick to convert png to jpg
• Use html2text to convert html to txt

Answer 3

That would do the rename; keep in mind that renaming a Word document won't cause it to become text, though.
