} I'm trying to see if the value of a parameter contains a given string
The right-hand-side of == in a [[ ]] construct is a glob pattern, so if
all you want is true/false, this works:
if [[ $foo == *pattern* ]]; then
# contains pattern
else
# doesn't contain pattern
fi
If you want to extract the matching string, see the M and S flags:
matching=${(SM)foo##pattern}
