verify command

Guy's

I have script doing many steps as the below ...

#############

## step1# mount all Files system
mount all

## step2# Start the application
/app/appsh
#############

but some time mount points will not be mounted completely so that will give an error if the next step started will sat err can not found /app

so I want some thing to verify from the mount points are mounted completely before sp the second step

Pls your advice and help ... :rolleyes:

how about
mount all || then or
mount all && then
