[TriLUG] possible awk/grep question

[jonc at nc.rr.com]

A little further offtopic but, I was playing with "getent" (on CentOS) and noticed that it only returns the first entry that matches its query. This could be misleading. As an example,
  getent services domain
    domain                53/tcp

which ignores the UDP entry (which is listed 2nd in the /etc/services file)... Perhaps I'm being too picky :-)

If you were using it for troubleshooting, you could end up going down the wrong rabbit hole.
