Scripting unix commands

[Rose Marie Mansell]

I am wanting to create a script that will save me some time and help prevent keystroke errors during recovery periods. I am wanting to execute several unix commands in a designated order but need to incoporate checks so that I know that a command completed successfully prior to moving onto the next command. The commands I am looking at are vgimport, vgchange, mount, vgcfgbackup. I am struggling with best approach...suggestions are appreciated.

If you better explain what exactly you want to automate then it would be easier to write script.

You can check the exit code for the command with:

echo $?

So, you can do somethig like:

RESULT=`command1; echo $?`

if [ $RESULT -eq 0 ]; then
echo "command executed correctly"
else
echo "Last command executed with errors"
exit 1
fi

RESULT=`command2; echo $?`

if [ $RESULT -eq 0 ]; then
echo "command executed correctly"
else
echo "Last command executed with errors"
exit 1
fi

.
.
.

RESULT=`commandN; echo $?`

if [ $RESULT -eq 0 ]; then
echo "command executed correctly"
else
echo "Last command executed with errors"
exit 1
fi
