Hi,
it would be nice to support this syntax for string searching:

aaa='My string'
if [[ "$aaa" == *"stri"* ]]; then echo "It's there!"; fi
if [[ "$aaa" =~ .*stri.* ]]; then echo "It's there!"; fi

[[ ]] is a bashism.

You can keep your scripts standard by using:

aa='My string'; if [ "${aaa##*stri*}" = "" ]; then echo "It's there!"; fi
