Top Forums Shell Programming and Scripting awk set $1 to itself, effect on $0 Post 302799923 by hanson44 on Sunday 28th of April 2013 08:05:28 AM

I had read the documentation before. It did not make it "crystal clear" to me. Of course, that's probably my fault. I'm sure all that documentation is easy to understand for everyone else. Smilie I understood about $0 being rebuilt. Now that I think about it more, it makes sense that when $0 is rebuilt, the only input is $1 so the new version of $0 has no blanks. Thanks.

MOTD.TAIL(5)						   Debian Administrator's Manual					      MOTD.TAIL(5)

NAME
motd.tail - Template for building the system message of the day DESCRIPTION
On Debian systems, the system message of the day is rebuilt at each startup, in order to display an accurate information. /etc/motd.tail is the file to edit permanent changes to the message of the day. OVERVIEW
The initiation script /etc/init.d/bootmisc.sh prepends a line containing information about the system to /etc/motd.tail and stores the resulting file in /var/run/motd. /etc/motd is a symbolic link to /var/run/motd. This is done to prevent changes to /etc as the system can not assume /etc to be writable. Changes to /etc/motd effectively end up in a file under /var/run which will be regenerated upon reboot. A symbolic link to a different file, such as /etc/motd.static disables this behaviour. FILES
