The for-loop comes from C, where it follows the form
Code:
for(statement1; statement2; statement3) {
}
which does effectively this:
Code:
statement1;
while(statement2) {
statement3;
}
It's usually used for(var=0; var<10; var++) but any valid expression will do. Most languages with for() loops allow them to be flexible like that, though few languages can cram as many things into one expression as C
In the BASH/KSH adaptation, you can put anything inside each statement that you might put inside a (( )) block, including nothing.

motd.tail
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.
