How to check a string in the variable

josephwong · #1 (**permalink**) 06-25-2006

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)?

Currently, I am using this:

if ( grep "desformat=PDF" $chkpdf 1>/dev/null )
then --$chkpdf is a file contains the string a parameter

Thanks.

Cheers,
Joseph
