Hi ,

I am using csh.
I tried using the below command as well.
What does this statement " sending output to nohup.out" means ? Does it mean my script can run with me exiting the command prompt window already ?
However, when i type " jobs -l ", no jobs seems to be running . Can some experts help ?

Code:
$ /bin/nohup mycshscript &
[7] 19804
$ Sending output to nohup.out

Code:
$ jobs -l 
$

Background process attempts I/O, hence the reason.

Better make your process read input from a file rather than a terminal

that should solve the problem

Hi matrixmadhan,

Don't really understand how you define reading input from a file rather than a terminal. Can you give me some process examples where process is reading from a file and process is reading from a terminal ?
