Refereing to elements in current command line

Refereing to elements in current command line

[zzapper]

Hi
Sorry if this is an old chestnut

I often type somethig like

> cp fredjoesid.php danjoesid.php

At Present I use i a binding Control-O to do

> cp fredjoesid.php fredjoesid.php
end then vi edit

But how else can I do this?

Sounds like a job for history-expansion:

[snip]
zsh% touch fredjoesid.php
zsh% cp fredjoesid.php danjoesid.php
zsh% !:0-1 !:1:s^fred^donny
cp fredjoesid.php donnyjoesid.php
zsh% print -l *.php
danjoesid.php
donnyjoesid.php
fredjoesid.php
[snap]

See 'man 1 zshexpn' /HISTORY EXPANSION for details.

Regards, Frank

perhaps with !#

   cp fredjoesid.php !#$:s/fred/dan

then tab to check that the last argument expands the way you want

Drew,
Yep that's what I was looking for

Summary AFAICT

For CURRENT line (the # designates current line)

!#:0    command
!#^     first parameter
!#:1    first parameter
!#:1-4  first 4 parameters
!#$     last parameter
!#*     all parameters
!#$:s/bash/zsh

For Previous Command (for comparison)
!!      repeat
!:0     command
!^      first parameter
!:1     first parameter
!:1-4  first 4 parameters
!$      last parameter
!*      all parameters
!!:s/bash/zsh

For last but one command
!-2:2   second parameter of second but last command
