thank you for the response however
this one didn't work since i 'm using a sentence as a string.
here is the response;

Code:
>more alphanumeric.sh
case "$1" in
     *[!a-zA-Z0-9]*) echo "non alphnumeric" ;;
     *) echo OK ;;
esac
>./alphanumeric.sh "this sentence doesn't contain any metacharacters"
non alphnumeric
>./alphanumeric.sh "this sentence contains * metacharacters"
non alphnumeric

###
also other than the alphanumerics, my sentence can also contain . or , or !
Can you help me with this?
