-e commandline
          may be used to enter one line of script.   Multiple  -e
          commands  may be given to build up a multi-line script.
          If -e is  given,  perl  will  not  look  for  a  script
          filename  in  the  argument  list.   On  MS-DOS, the -e
          switch will not work well unless perl is  run  from  an
          MKS tool, such as the Korn shell.  This is due to limi-
          tations in the standard method of MS-DOS argument pass-
          ing.
