Why can't I use "nice" in an bash shell script?

Hi there,

Why can't I use the nice command inside a script?  And what can I use instead?  

The code below does not work but if I remove the "nice +20" it works fine but I bully everyone else's jobs out of the queue.  any thoughts?



cd mydirectory
nice +20 ./myprogram1
nice +20 ./myprogram2
nice +20 ./myprogram3
nice +20 ./myprogram

PS when I preview the question my PLUS symbols disappear for some reason, but rest assured I use "nice" then a space then a plus then the number 20.....

hm, i check the syntax in man. try using "nice -n -20 ./program" to run it with most favorable scheduling, or "nice -n 19 ./program" fo least favorable.
