Extract filename and extension in Bash

Question

I want to get the filename (without extension) and the extension separately.

The best solution I found so far is:

NAME=`echo \"$FILE\" | cut -d\'.\'          


        

Answer 1

I think that if you just need the name of the file, you can try this:

FULLPATH=/usr/share/X11/xorg.conf.d/50-synaptics.conf

# Remove all the prefix until the "/" character
FILENAME=${FULLPATH##*/}

# Remove all the prefix until the "." character
FILEEXTENSION=${FILENAME##*.}

# Remove a suffix, in our case, the filename. This will return the name of the directory that contains this file.
BASEDIRECTORY=${FULLPATH%$FILENAME}

echo "path = $FULLPATH"
echo "file name = $FILENAME"
echo "file extension = $FILEEXTENSION"
echo "base directory = $BASEDIRECTORY"

And that is all =D.
