Top Forums Shell Programming and Scripting Daemonizing a bash script Post 302186604 by viko on Thursday 17th of April 2008 02:26:06 PM
Old 04-17-2008
Ok. era, i've tried debugging and I've progressed a little.

I've excecuted it on this way:

nohup /~/any.sh 0<&-

so, the output (both STOUT & STERR) were redirected to ./nohup.out


i've checked at nohup.out and i've found my problem:

/usr/bin/command[8]: [argument: not found
/~/any.sh: syntax error at line 14: `DAY=$' unexpected


so, I've realized that I were running it without bash command. So that, I think it was trying to run it on sh, and that fails.



I'm still not understanding what really the deamon does do. I mean: does it run as if it was in continous loop, or have I to make explicity, the loop in the command?.


Perhaps is a good idea too, to force script using bash, but #!/bin/bash does not work for me since bash isn't there. Actually, bash is in diferent routs depending on machine, and i want to do a complete unique code.


thanks both you guys


regards!

nohup

NOHUP(1)                                                           User Commands                                                          NOHUP(1)

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 an unreadable file.  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.
