bash string compare to multiple correct values

Question

i have the following piece of bashscript:

function get_cms {
    echo \"input cms name\"
    read cms
    cms=${cms,,}
    if [ \"$cms\" != \"wordpress\" &am         


        

Answer 1

Instead of saying:

if [ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]; then

say:

if [[ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]]; then

You might also want to refer to Conditional Constructs.
