There is no specified if the content of destination file can be replaced. So i suppose that it can.. in that case these commands are correct: cat /etc/testfile | grep abcde > /tmp/testfile OR grep abcde /etc/testfile > /tmp/testfile In case that content of destination file should not be replaced, following command will work: cat /etc/testfile | while read line; do echo $line | grep abcde | tee -a /tmp/testfile; done There is missing ";" in "correct answer" here, so the command from there will work if you will copy paste it but if you need to write it on your own, you must add the ";" or use bash script!
