Stripping out extension in file name
This command gives me just the filename without any extension:
evrvar =`echo filename.tar | sed 's/\.[^.]*$//'`

I am trying to make a change to this command... to make it work for... filename.tar.gz to get just the filename....

currently the command gives me filename.tar by removing only gz... I am new to regular expression... pls help.

Thx.

try this:
Code:
echo filename.tar.gz |awk -F. '{ print $1 }'

or
Code:
echo filename.tar.gz |cut -d'.' -f1

or sed solution
Code:
echo "filename.tar.gz" | sed 's/\(.*\)\.\(.*\)\.\(.*\)/\1/g'

or
Code:
echo "filename.tar.gz" | sed 's/.......$//g'

If filename does not contain period(s):

Code:
$ fname="filename.tar.gz"
$ echo "${fname%%.*}"
filename


Otherwise:

Code:
${fname%.*.*}

Thanks for the replies.

can this regular expression be made possible to use for both filename.gz & filename.tar.gz

I want to get filename for both of these commands as just filename only:
echo "filename.tar.gz" | sed 's/\(.*\)\.\(.*\)\.\(.*\)/\1/g'
echo "filename.gz" | sed 's/\(.*\)\.\(.*\)\.\(.*\)/\1/g'

thanx in advance.

You could use either the awk or the cut solutions they will work in all the scenarios. Here is the sed solution to generalize on both the occasions.

Code:
 echo "filename.tar" | sed "s/\([^.*]\)\.\(.*\)*$/\1/g"
