Description Steve Bonneville 2005-12-02 11:56:13 EST 
Description of problem:

The man page and info pages for kill(1) list options that don't exist.

The man page claims there are -a and -p options to kill(1).

The info page claims there are -t/--table options which are synonyms for -l,
it also claims kill supports --help and --version which it does not.  However,
the info page for kill appears to come from the coreutils package, while the man
page for kill(1) appears to come from the util-linux package, as does the
version of /bin/kill that we ship.  (/usr/bin/kill is a symlink to /bin/kill).

Running /bin/kill without arguments displays the following usage message:

[user@foobar ~]$ kill
kill: usage: kill [-s sigspec | -n signum | -sigspec] [pid | job]... or kill -l
[sigspec]

Version-Release number of selected component (if applicable):

util-linux-2.12a-16.EL4-12
coreutils-5.2.1-31.2
Comment 1 Karel Zak 2006-01-03 04:42:54 EST 
There're two "kill" implementation. The man page kill(1) is correct, because
it's for /bin/kill.

the kill command from util-linux:

  $ /bin/kill
  usage: kill [ -s signal | -p ] [ -a ] pid ...
         kill -l [ signal ]

bash buil-in command:

  $ help kill
  kill: kill [-s sigspec | -n signum | -sigspec] [pid | job]... or kill -l  
[sigspec]

By the way, see kill(1) man page, there is note about it: "Most modern shells
have a builtin kill function..."
