Create an alias for "pipe grep"

Question

I would like to create an alias for | grep

eg, for example be able to write:

ps -axf G chrome instead of ps -axf | grep chrome

I've written the following in my aliases file of oh-my-zsh:

alias -g G= '| grep --color'

However, this doesn's seem to work.

Any idea why ?

EDIT

I get the following error when I write ps -axf G chrome

error: must set personality to get -x option

Usage:
 ps [options]

 Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
 for additional help text.

For more details see ps(1).

It seems that the G is interpreted as being part of the ps command

"Doesn't seem to work" is vague. What exactly happens when you try to use the alias? Do other aliases in the same file work properly? — user2357112, Jul 16 '14 at 08:42
It means to set the alias globally. I thought that would help, but it's exactly the same if I use it or if I don't — edi9999, Jul 16 '14 at 08:47

I have

alias -g G=' | grep -i '

so the syntax seems OK

so I can do :-

cat file.txt G fred

are you actually running zsh (echo $SHELL)

`echo $SHELL` gives back `/usr/bin/zsh` – edi9999 Jul 16 '14 at 08:49

Your alias statement can't have space between assignment:

alias -g G='| grep --color'

Do you know how to achieve that in fish-shell? – xliiv Jul 07 '15 at 07:03

@xliiv fish doesn't seem to have real aliases, only functions; so it's likely not possible. – konsolebox Jul 08 '15 at 08:41
