Re run previous command with different arguments
!:0 should do the trick. From the zsh documentation:
Word Designators
A word designator indicates which word or words of a given command line
are to be included in a history reference. A `:' usually separates the
event specification from the word designator. It may be omitted only
if the word designator begins with a `^', `$', `*', `-' or `%'. Word
designators include:
0 The first input word (command).
n The nth argument.
^ The first argument. That is, 1.
$ The last argument.
% The word matched by (the most recent) ?str search.
x-y A range of words; x defaults to 0.
* All the arguments, or a null value if there are none.
x* Abbreviates `x-$'.
x- Like `x*' but omitting word $.
(It works with bash, too.) There’s also !-1 if you find that more convenient to type.
#TL;DR Alt+0+.: inserts last command without the arguments
Tested on Ubuntu 18.04 with the default keybinding settings (i.e Emacs keybindings)
You can combine keyboard shortcuts
Let's consider the last command to be:
mv foo bar
up , Ctrl+w: last command without the last word = mv foo
Alt+0+.: first argument of last command = mv
Some useful shortcuts:
Alt+.: insert last argument from last command (repeat to go back in history)
Alt+number+.: insert #nth last argument from last command (repeat to go back in history)
Alt+- , number , Alt+., zsh: Alt+-+#+.: insert #nth first argument from last command (repeat to go back in history)
Cut commands (relative to cursor's position)
Ctrl+w: cuts last word
Alt+d: cuts next word
Ctrl+k: cuts everything after
Ctrl+u, zsh: Alt+w: cuts everything before
zsh: Ctrl+u: cuts the entire command (In bash you can combine Ctrl+u , Ctrl+k)
Ctrl+y: paste characters previously cut with any Cut command. In bash You can chain cut commands, and Ctrl+y will paste them all.
Ctrl+_: undo last edit (very useful when exceeding Ctrl+w)
Ctrl+left: move to last word
Ctrl+right: move to next word
home or Ctrl+a: move to start of command
end or Ctrl+e: move to end of command
To see all shortcuts available
- bash:
bind -lp - zsh:
bindkey -L
Unfortunately there are some limitations
"words" only includes a-zA-Z characters, so any symbol character will stop word-shortcuts.
So if last argument was a url and you want to erase it with Ctrl+w it will be a pain.
E.g: curl -I --header "Connection: Keep-Alive" https://stackoverflow.com/questions/38176514/re-run-previous-command-with-different-arguments
To erase that url using Ctrl+w, you'd have to repeat it 12 times.
It would be great to have similar shortcuts that only stops at the space character
