Top Forums Shell Programming and Scripting Linux csh script going to Suspended (tty output) when running with & (bg) Post 302912338 by Corona688 on Thursday 7th of August 2014 11:48:43 AM

If a background process tries to read from the terminal, it will be stopped. This is normal terminal and shell behavior. Only foreground processes are allowed to control the terminal like that.

To prevent it from reading from the terminal, run it with nohup to prevent it from accessing the terminal. This will redirect stdin/stdout/stderr automatically. stdin will connect to /dev/null, while stdout and stderr will be saved to a file in the current directory.

Code:
nohup run_server.csh

NAME
nohup - run a command immune to hangups, with output to a non-tty SYNOPSIS
nohup COMMAND [ARG]... nohup OPTION DESCRIPTION
Run COMMAND, ignoring hangup signals. --help display this help and exit --version output version information and exit If standard input is a terminal, redirect it from /dev/null. If standard output is a terminal, append output to 'nohup.out' if possible, '$HOME/nohup.out' otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use 'nohup COMMAND > FILE'. NOTE: your shell may have its own version of nohup, which usually supersedes the version described here. Please refer to your shell's doc- umentation for details about the options it supports.
