You have to be more clear about when you want this to run.
Do you want this to only run while you are logged-in, or
do you want this to run whenever your system is booted up ?
IF when logged in, you can just use a test to see if it's already running, and
then start with a bash command like ...
pgrep proj >/dev/null || path/to/proj
If you want it to run all the time - even when logged out, then create a service - it's pretty simple.
# cd /etc/rc.d/init.d
copy & edit a simple service script to meet your needs like ...
# cp readahead myproj
# sed -i -e 's/5 96 99/345 30 80/g' myproj
# sed -i -e 's,/usr/sbin/readahead,path/to/proj,' myproj
# gedit myproj
<< change the 'start()' function to start proj with correct args >>
Then install the service with
# chkconfig --add myproj
# chkconfig --level 345 myproj on
and start it for the first time with ,,,
# service myproj start
It will start upon boot to init level 3,4,5 from then on.
