Ack. Not commenting on the script itself, but this is dangerous. Depending on the shell, filename will be rewritten immediately due to the '>' redirection, and thus this will end up making the file blank. Also, Google for "Useless use of cat". To run a well-behaved command, called say cmd, that reads content from filename on standard input, does some processing on the content, and rewrites it to the same filename, do cmd < filename > tmp.$$ && mv tmp.$$ filename Regards, Gora _______________________________________________ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - September 28-29, 2007 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
