Running script in background


Hi,

I have written a script called run. What it does is it executes a C program and stores the result in a text file (appends to it) . This process goes on because i have to log the data. I was wondering if there is anyway i can run the script in the background cos once i type

./run

at the command prompt, i dun get back to the prompt again as the script keeps on running. I need to go back to the prompt. How do i manage this ?? I am relatively new to Linux.

you can view running processes with the "ps" command, use "ps aux" to view ALL running processes (see "man ps" for more info). you can use this command: "ps aux | grep run" to view only the "run" process. for realtime monitoring running processes, use the "top" command. you can run different scripts in background, but if you logout the terminal (or xterm) the process will die, because it's a child process of the terminal.

if you want to view how much cpu, memory, etc. resources in real time that are being used you can use the
$ top
command as well as control what you want to see by going to the man pages
$man top
