Need Help using sed command(very urgent)
Hi all,

Actually i want to delete the .ps extension from package1.ps string by using sed.

ps_file="package1.ps"
echo $ps_file
sed s/.ps//g $ps_file
echo $ps_file

When i am running this one i am getting the following error

Any specific reason for using sed..?

How about.. " mv package1.ps package1"

Hi The below script would work for you,

ps_file="package1.ps"
echo $ps_file
ps_file1=`echo $ps_file| sed "s/.ps//g"`
echo $ps_file1 ---> This variable hold the file name "package1"

Yes,

Because i have one file test.ls which contains following files.

package1.ps
package2.ps
package3.ps
package4.ps
package5.ps
package6.ps
package7.ps

and i want to remove all the extensions of .ps

Suppose that you keep your *.ps files in psdir directory:

Code:
for i in `ls /psdir/*.ps`
do
  j=`echo $i|sed 's/.ps//'`
  mv $i $j
done
