Top Forums Shell Programming and Scripting using mutiple "nohup" to execute multiple commands. Post 302290906 by otheus on Tuesday 24th of February 2009 08:57:58 AM

The second is better. However, in both cases, output may get corrupted, since two nohups running at once will both try to output to nohup.out. I think a better idea would be to do split them into two separate rsh's.
Code:
rsh SERVER_NAME -n '( $SCRIPTS_DIR/abc.pl &> $HOME/abc.out) &'
rsh SERVER_NAME -n '( $SCRIPTS_DIR/xyz.ksh &> $HOME/xyz.out ) &'

By putting the execution of the shell into a sub-shell (...) you avoid the need for nohup. Once it is backgrounded and output redirected, the process won't see signals like SIGHUP when the parent shell executes.

Because the shell exits almost immediately, rsh should return very soon thereafter, and thus it is not needed to put rsh in the background.

RSH(1)							      General Commands Manual							    RSH(1)

NAME
rsh - remote shell SYNOPSIS
rsh [-n] [-l username] host [command] host [-n] [-l username] [command] DESCRIPTION
Rsh connects to the specified host, and executes the specified command. Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally terminates when the remote command does. The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote name must be equivalent (in the sense of rlogin(1)) to the originating account; no provision is made for specifying a password with a com- mand. If you omit command, then instead of executing a single command, you will be logged in on the remote host using rlogin(1). Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote machine. Thus the command rsh otherhost cat remotefile >> localfile appends the remote file remotefile to the localfile localfile, while rsh otherhost cat remotefile ">>" otherremotefile appends remotefile to otherremotefile. OPTIONS
-l username Specify the remote user name. -n Connect standard input of the remote command to /dev/null. Do this if rsh should not inadvertently read from standard input. SEE ALSO
rcp(1), rlogin(1), rhosts(5). BUGS
You cannot run an interactive command (like rogue(6) or vi(1)); use rlogin(1). 4.2 Berkeley Distribution April 29, 1985 RSH(1)
