Exit a shell script

Shell Programming and Scripting

Hi Guys,

How can I exit from the shell script if a condition is not met?

Thanks in advance...

Use this :stuck_out_tongue:

if [ condition not met ]; then
echo "Exiting"
exit
fi

Yes, but I think the point may be that the OP is missing is how to use the exclamation point to reverse the sense of a test.

if [ ! "x$abc" = "x" ]
then    echo '$abc is not an empty string'
        exit 1
fi
