Top Forums UNIX for Beginners Questions & Answers Simple shell script function Post 303031411 by nezabudka on Thursday 28th of February 2019 02:08:41 AM

Code:
if [ $? -ne 0 ]; then
    :
else
    echo "FAIL"
    return
fi
echo "OK:PASSED"

Only I don't understand a little why not 0 is not an error? And there is no operator "done"

Code:
vgcheck() {
        lsvg -o | 
                while read vg; do
                        lsvg -p $vg | grep Missing
                        if [ $? -ne 0 ]; then
                                :   
                        else
                                echo "FAIL"
                                return #if you need exit
                        fi
