   1 The following are demonstrations of the whatexec.d script.

   4 Here we run it while a few commands are also executed,
   5
   6    # ./whatexec.d
   7    PEXEC            EXEC                                   OK TYPE
   8    bash             /usr/bin/clear                          Y #!/u\0
   9    bash             /sbin/sh                                Y \177ELF\0
  10    clear            /usr/bin/tput                           Y \177ELF\0
  11    bash             /export/home/brendan/DOOM.EXE           N MZ\644\0
  12    ^C
  13
  14 whatexec.d has first found that "clear" was run, which has a type that
  15 begins with "#!" - a script. clear runs "sh" and "tput", both ELF files.

  17 We finish by attempting to run a MZ file, "DOOM.EXE", which is rejected
  18 (OK is "N").
