K-shell script argument

Comment:

I need to do and IF statement that checks to see if a variable contains a particular value. ex. x=redcars. IF x contains "car" do whatever. Thanks for the help. I've been trying to figure this out for awhile. Paul

x=redcars if [ "$x" == "redcars" ] then echo do something fi this is how I'd do it. When using string variables, I put the quotes around the variable so that if it is empty, it won't error out.

if [ `echo $x | grep -c car` -gt 0 ] ; then the above would check for the string car within the variable if you need to check substring.
