Use another character instead of '/' as a delimiter for the 's' command and you won't have to do escaping. e.g: $ echo '%nice ALL=NOPASSWD: /bin/nice,/usr/bin/renice' |sed -e 's|/bin/nice,||' %nice ALL=NOPASSWD: /usr/bin/renice Here I used '|' where '/' is normally used. So basically you could use something like: sed -ie -e 's|/bin/nice,||' /etc/sudoers Or, following the recomendations in that file, something like: EDITOR="sed -ie -e 's|/bin/nice,||'" visudo (UNTESTED) -- Tzafrir Cohen | New signature for new address and | VIM is http://tzafrir.org.il | new homepage | a Mutt's [EMAIL PROTECTED] | | best ICQ# 16849755 | Space reserved for other protocols | friend ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
