Top Forums Shell Programming and Scripting [Solved] Unable to mailx new $pid for a script restart Post 302818007 by Don Cragun on Thursday 6th of June 2013 08:17:30 PM

So, does:
Code:
/usr/bin/sh $BATDIR/$BATNAM

just restart the process asynchronously and exit, or is it supposed to run forever? Does the trace of the script produced by sh -x show that the two sleeps, mailx, date, and echo are run when the batch is not running? Should:
Code:
   /usr/bin/sh $BATDIR/$BATNAM
   sleep 10
   mailx -s "${SERVER} ${BATNAM} restarted" petey
   sleep 10
   echo "$pid" > $SLOG/"$BATNAM-restart-on--`date +%F-%T`"

be changed to:
Code:
   /usr/bin/sh $BATDIR/$BATNAM&
   pid=$!
   mailx -s "${SERVER} ${BATNAM} restarted" petey
   echo "$pid" > $SLOG/"$BATNAM-restart-on--`date +%F-%T`"

Why does your script initialize BATPF twice?

Why bother setting pid to an empty string just before exiting when the service is running?

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5) Jan 2006 service(8)
