Hi everyone!
I have a question.
How can I limit the length of a variable?
If its bigger than 9 for example to stop sa script from running.

Hi,

if $var ist your variable, ${#var} will give you the length
of the content of ${var}. So to stop your script try a
test like the one below:

if [[ ${#var2} -gt 9 ]] 
then  
    echo "too big" 
    exit 1
else 
    echo "just fine"
fi
