No, don't use cat. It will work part of the time, but if two processes try to log something at the same time things will get garbled or lost or I'm-not-sure. Use logger (for shell access) or syslog(3) (for C access). For example, I just did this: # logger this was written with logger and my term is $TERM And in /var/log/message I see: Jul 23 09:49:59 localhost logger: this was written with logger and my term is dumb You can also pipe things into logger, such as this: # date | logger To get this in /var/log/messages: Jul 23 09:53:24 localhost logger: Wed Jul 23 09:53:24 EDT 2003 There are various switches to logger to modify its behavior, including what file to log to, etc. -kb, the Kent who didn't know about logger until now, but he knew simple redirection was a bad idea and started looking through a couple man pages. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
