This wait for kmail code snippet falls right thru even when kmail isn't
running:
==========
DetectKmail="pgrep kmail"
until :
do
sleep 3
$DetectKmail
done
==========
As I read the bash docs in the scripting guide, the until loop will run
till a non-zero output is obtained from the last command in the loop.
while list; do list; done
until list; do list; done
The while command continuously executes the do list as long
as the last command in list returns an exit status of zero. The until
command is identical to the while command, except that the
test is negated; the do list is executed as long as the last command in
list returns a non-zero exit status. The exit status of the
while and until commands is the exit status of the last do list command
executed, or zero if none was executed.
If kmail isn't running $DetectKmail's return s/b a null. What is my
mistake? Ahh, s/b a "while" :, ENOTENOUGHCAFFIENE ;-)
Off to test that.
Thanks Duncan
