how to start a program in the back ground


I've tried searching it and everything I've seen posted on different sites didn't work.

i have my program set up in vi
it runs the way it is supposed too
but i need it to start in the back ground
I've tried bg
$bg
nohup

the program runs fine when running it in the fore ground but i need it to start up and run in the background.

any idea's on what i'm doing wrong,

this is what it looks like now

/labs/bash/count.sh &
mypid=$!
sleep 5
kill $mypid

As I said in your other post, using '&' puts it in the background.... incidentally, you should have carried on in that thread/qn, not start a new one.

In any case, you REALLY need to read/reference these
http://rute.2038bug.com/index.html.gz
http://tldp.org/LDP/Bash-Beginners-G...tml/index.html
http://www.tldp.org/LDP/abs/html/

and decide exactly what you want. Just try the cmds in there until you understand...

yea your right i should have,,, i thought i was done with the program but for some reason it won't run in the background. I have the & in the program. but i can see it counting. I had already marked the last q as solved so i thought i needed to start a new one.

thank you very much for the links, any information i can read up on is a great help

When you say:

You are aware that if your count.sh script does something like count from 1 to 10 and echo those numbers to the screen
that placing the running script in the background will not stop this from happening?
