Full Discussion: rerun a script if aborted and exited
Top Forums UNIX for Advanced & Expert Users rerun a script if aborted and exited Post 302169377 by bakunin on Thursday 21st of February 2008 05:09:33 AM

If your script sets exit codes (as, in an ideal world, should any process) it is not too hard to use a script wrapper:

First your_script.sh skeleton:
Code:
#! /bin/ksh

.... your code ....

if [ ... some condition ...] ; then
     print - u2 "Houston, we have a problem. Aborting...."
     exit 1      # aborted for some reason
fi

... more of your code ....

exit 0      # normal exit

Now the wrapper.sh skeleton:

Code:
#! /bin/ksh

while : ; do
     your_script.sh         # call your_script.sh
     if [ $? -eq 0 ] ; then
          break         # exit the loop if your_script.sh finished normally
     fi
done

exit 0

I hope this helps.

uudemon.cleanu

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
