It also preserves the permission bits and (usu) ownership of the original. Nice!

When sedding, I recommend first cp /etc/someimportantconfigurationfile \ /etc/someimportantconfigurationfile.bak and then sed </etc/someimportantconfigurationfile \ >/etc/someimportantconfigurationfile.bak \ etc If at first you don't succeed, you can try again without recovering what you did wrong. It's also good documentation, for when you do the virtual paperwork later;-) Mostly, I do this in a script, and the script first tests for the existance of the backup, creates it if there isn't one. Then, it's just a matter of hacking and running until the script works. Interactively, I'm more likely to use ed or ex, and we're back where we started;-) -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Please do not reply off-list ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
