cut filename extension

Shell Programming and Scripting
1

I need a small script (sh) to remove in a variable the filename extension.
Example:
f = "testfile.txt"
and I need a $a with "testfile".
Some one a idea?

f=testfile.txt ; a=`basename $f ".txt"` ;echo $a

Thanks :slight_smile:

Using shell builtins (sh, bash and probably others too)

#!/bin/sh

a='testfile.test.txt'

echo "Filename: ${a%.*}"
echo "Extension: ${a##*.}"

exit 0

echo $FILENAME |sed 's/\(.*\)..../\1/'
