distinguish the extension of a file

tbeghain · #1 (**permalink**) 06-12-2007

Hello,

In a script shell, I have a variable containing the name of a file and I would like to distinguish the name from the extention of the file. For example, the file 'myfile.txt' is in a variable called $VAR. How can I obtain 2 variables, one with 'myfile' and the other with 'txt' ?
Thank you

Script test

#!/bin/ksh
name=$1
pre=`echo $name | cut -f 1 -d .`
pst=`echo $name | cut -f 2 -d .`
echo $pre
echo $pst

To run type

./test test.txt

Output

test
txt

Or...

Code:

VAR='myfile.txt'
pre=${VAR%.*}
pst=${VAR##*.}
