goto in shell script?

rei · #1 (**permalink**) 07-16-04, 07:50

i have a group of commands to be executed in a shell script
(each group has a lists of commands)
if any commands failed, program will be terminated.

i want to code my shell script, so that the next time it restarts, it will start from the point of group where it is terminated.

let's say i gave a number to every group.

so, next time when i start the script, i can give the process number as arguments to the shell script.

./myshell.sh 3 <-- starts from no 3 group

by default, it starts from the beginning.

may i know in what way i can write this?
how to give number to each group?
any tutorial help with example?

thanks

Try this:

Code:

#!/bin/ksh
restart=${1:-0}
if [ restart -eq 0 ]
then
  echo "Starting at the top"
  ...
  (( restart += 1 ))
fi
if [ restart -eq 1 ]
then
  echo "Starting at $restart"
  ...
  (( restart += 1 ))
fi
if [ restart -eq 2 ]
then
  echo "Starting at $restart"
  ...
  (( restart += 1 ))
fi
... etc ...
