hi,
I have a variable var1 as follows in the script.
var1="one two three desformat=PDF xyz"
I would like to check whether $var1 has a string "desformat=PDF" or not.
Is there any command I can use (not need to creat a file)?

if ( grep "desformat=PDF"... (1 Reply)
Logic of code
if ( $var is a number ) {
Do something
}
else {
Do something else
}
My question is: How do I check if a variable is a number. All the reg ex that I came up with to match this is failing. Please help. (3 Replies)
