store some parameters/arguments for later use

store some parameters/arguments for later use

[zzapper]

Hi
I'm sure Bart's told me about this b4 and I may have it somewhere

The ability to store some parameters/arguments for later use 

eg

> ls x1 x2 x3
save_parameters
...
...
...
vi recall_parameters

Hi everyone!
I'm a happy lurker of zsh-*, now I figured I could even be helpful to
someone else :)

If the `ls' command was command number, say, 15 in history, you would be
able to use its arguments later with:

!15:0 == "ls"
!15:1 == "x1"
!15:2 == "x2"
.. And so on

Note that you can do it also this other way:

!ls:0 == "ls" # very useful example :)
!ls:1 == "x1"
!ls:2 == "x2"
.. And so on

HTH, bye

Hi
What I've come up with is

spar () {
        P="$(history -n -1|sed 's/^[^ ]* //')"
}

and then anytime later I can say

vi $P

If you want to save a process, you can try:

   $ echo a b c
   $ P="!:*"
   $ echo $P

There's probably an alias you could come up with to ease the assignment.
!:* grabs all but the first word from the previous command.
