💡 On a Linux system using bash, you can case insensitively compare text by using ,, (lowercase) or ^^ (uppercase) parameter expansion modifiers e.g. EDITION=CommUNITY if [[ ${EDITION,,} = community ]]; then echo "yes" fi ${EDITION,,} converts value to lowercase #ZikTIPs #techtips #Linux #opensource
💡 TIP: On a Linux system using bash, you can compare text strings without worrying about upper or lowercase by using the ,, (lowercase) or ^^ (uppercase) parameter expansion modifiers e.g.

EDITION=CommUNITY

if [[ ${EDITION,,} = community ]]; then
    echo "Community"
fi

${EDITION,,} converts the value to lowercase.
