[PATCH 0/3] _pgrep: fixes and improvements

[PATCH 0/3] _pgrep: fixes and improvements

[Kosuke Asami]

pgrep completion uses 'ps' commands, but in BSD environment, it has
wrong 'ps' options, so it doesn't work showing error messages like a
following line.

ps: illegal argument: co

These patches fix this problem.

And, pgrep options are different between operating systems.
They also deal with it.

Kosuke Asami (3):
  _pgrep: add missing options in each environments
  _pgrep: fix commands used in completion
  _pgrep: tidying up

[PATCH 2/3] _pgrep: fix commands used in completion

[Kosuke Asami]

The option style in ps command are different between BSD and Linux.
For example, 'ps -A co cmd=' command cannot be executed in BSD
environment, so zsh completion always shows error like 'ps: illegal
argument: co' and cannot be used.
