[Bug 1030025] Re: Missing programmable bash completions for host and ping commands

[Peter Cordes]

In Trusty, ping is handled by _ping, so custom code just for ping.
host just gets the generic _minimal.

completion for host was removed in commit
bd482ca2f221323aa461ca75c9457ec11f43570e

   host, nslookup: Remove completions for bind utils from
bash_completion.

   This fixes tests on systems without bind.

https://alioth.debian.org/plugins/scmgit/cgi-bin/gitweb.cgi?p=bash-
completion/bash-
completion.git;a=object;h=bd482ca2f221323aa461ca75c9457ec11f43570e

(followed by a commit that reverted that, then followed by a commit that
reverted the reversion, putting this commit back in.)

 Seems like a crappy reason to take out a useful completion.

Title:
  Missing programmable bash completions for host and ping commands

Status in bash-completion package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  It seems that the host and ping programmable completions are no longer
  available in quantal?

  [hloeung at darkon etc]$ complete | grep known_hosts
  complete -F _known_hosts rlogin
  complete -F _known_hosts ftp
  complete -F _known_hosts tracepath6
  complete -F _known_hosts tracepath
  complete -F _known_hosts mtr
  complete -F _known_hosts traceroute6
  complete -F _known_hosts fping
  complete -F _known_hosts ssh-installkeys
  complete -F _known_hosts rsh
  complete -F _known_hosts dig
  complete -F _known_hosts telnet
  complete -F _known_hosts showmount
  complete -F _known_hosts fping6
  complete -F _known_hosts traceroute
  [hloeung at darkon etc]$ complete | grep known_hosts | wc -l
  14

  On a precise host, I get:

  hloeung at hadar:~$ complete | grep known_hosts
  complete -F _known_hosts rlogin
  complete -F _known_hosts ftp
  complete -F _known_hosts tracepath6
  complete -F _known_hosts host
  complete -F _known_hosts tracepath
  complete -F _known_hosts ping
  complete -F _known_hosts mtr
  complete -F _known_hosts traceroute6
  complete -F _known_hosts fping
  complete -F _known_hosts ping6
  complete -F _known_hosts ssh-installkeys
  complete -F _known_hosts rsh
  complete -F _known_hosts dig
  complete -F _known_hosts telnet
  complete -F _known_hosts showmount
  complete -F _known_hosts fping6
  complete -F _known_hosts traceroute
  hloeung at hadar:~$ complete | grep known_hosts | wc -l
  17

  I can't seem to recall the last time host and ping used to work but
  I'm pretty sure it's only started recently? Any chance someone could
  take a look?

  
  Thanks,

  Haw
