Full Discussion: How to redirect grep command output to same file

Hi Eshwar,

do it with "sed" rather. The "-i" switch has the "in-place" editing.

Code:
sed -ni '/pattern/p' file

However if something goes wrong, you can backup the file . The "-i" switch has that facility.
Code:
sed -ni.bak '/pattern/p' file

This also create a backup of the original file in addition to doing your job file - file.bak

Regards,
Gaurav.
