Instead of saying   if     cms      wordpress   amp  amp    cms      meganto   amp  amp    cms      typo3     then   say   if      cms      wordpress   amp  amp    cms      meganto   amp  amp    cms      typo3      then   You might also want to refer to Conditional Constructs

If the main intent is to check whether the supplied value is not found in a list  maybe you can use the extended regular expression matching built in BASH via the  equal tilde  operator  see also this answer    if        cms       wordpress meganto typo3       then get cms   fi   Have a nice day

As  Renich suggests  but with an important typo that has not been fixed unfortunately   you can also use extended globbing for pattern matching  So you can use the same patterns you use to match files in command arguments  e g  ls   pdf  inside of bash comparisons   For your particular case you can do the following    if       cms        wordpress magento typo3       The   means  Matches one of the given patterns   So this is basically saying cms is not equal to  wordpress  OR  magento  OR  typo3   In normal regular expression syntax   is similar to just   wordpress magento typo3     Mitch Frazier has two good articles in the Linux Journal on this Pattern Matching In Bash and Bash Extended Globbing   For more background on extended globbing see Pattern Matching  Bash Reference Manual

Maybe you should better use a case for such lists   case   cms  in   wordpress meganto typo3      do your else case                 do your then case        esac   I think for long such lists this is better readable   If you still prefer the if you can do it with single brackets in two ways   if     cms     wordpress -a   cms     meganto -a   cms     typo3    then   or  if     cms     wordpress    amp  amp      cms     meganto    amp  amp      cms     typo3    then
