Removing file extensions with sed May 12th, 2010

I need the following sed one-liner periodically, and I thought it was useful enough to share here. Other versions I’ve seen chopped off everything after the first dot, which doesn’t work for files with a dot in the basename. This one does:

sed s/\.[^\.]*$//

Sample Usage:

bsterne@zodiac:~$ ls /video | sed s/\.[^\.]*$// | head -n5

    Why not simply use bash parameter expansion as follows :

    “i” being the variable storing the file name :
    FILENAME=”${i%.*}”; # matches longuest chain until last “.” is met.
    FILEEXT=”${i##*.}”; # matches shortest chain starting with a “.” (so usually the extension)
