Explain what's wrong? Syntax is wrong because you are missing "OR" , i.e "||", at the end of each line...
Code:
      if [ "$filetype" = "perl" ] || [ "$filetype" = "NULL" ] || \
         [ "$filetype" = "csh" ] || [ "$filetype" = "ksh" ] || \
         [ "$filetype" = "pm" ] || [ "$filetype" = "pl" ] || \
         [ "$filetype" = "awk" ] || [ "$filetype" = "sh" ]
      then
            :
      fi

..but you could use case instead...
Code:
      case "$filetype" in
            perl|NULL|[ck]sh|p[ml]|awk|sh)  :
            ;;
      esac
