How can grep or egrep pattern in a file and print the pattern only? I will not print the whole line. e.g. to search the email address in /var/log/mail.log. I am wondering is it possible to achieve this without writing a perl script? -- To UNSUBSCRIBE, email to debian-user-request@lists.debian.org with a subject of "unsubscribe". Trouble?
