# Shortcuts
|
|
|
|
*For Ubuntu's default keybinding settings (i.e Emacs keybindings)*
|
|
|
|
## Insert previous arguments
|
|
- <kbd>Alt</kbd>+<kbd>.</kbd>: insert last argument from last command.
|
|
- <kbd>Alt</kbd>+<kbd>number</kbd>+<kbd>.</kbd>: insert #nth last argument from last command.
|
|
- <kbd>Alt</kbd>+<kbd>-</kbd> , <kbd>number</kbd> , <kbd>Alt</kbd>+<kbd>.</kbd>, **zsh:** <kbd>Alt</kbd>+<kbd>-</kbd>+<kbd>#</kbd>+<kbd>.</kbd>: insert #nth first argument from last command.
|
|
|
|
*In Linux you can repeat commands to go back in history*
|
|
|
|
### Example:
|
|
|
|
Last command is:
|
|
|
|
mv foo bar
|
|
|
|
- <kbd>Alt</kbd>+<kbd>0</kbd>+<kbd>.</kbd>: insert first argument of last command = `mv`
|
|
- <kbd>Alt</kbd>+<kbd>2</kbd>+<kbd>.</kbd>: insert last 2nd argument of last command = `foo`
|
|
- <kbd>up</kbd> , <kbd>Ctrl</kbd>+<kbd>w</kbd>: last command without the last word = `mv foo`
|
|
|
|
|
|
## Cut/Paste commands
|
|
*(relative to cursor's position)*
|
|
- <kbd>Ctrl</kbd>+<kbd>w</kbd>: cuts last word
|
|
- <kbd>Alt</kbd>+<kbd>d</kbd>: cuts next word
|
|
- <kbd>Ctrl</kbd>+<kbd>k</kbd>: cuts everything after
|
|
- <kbd>Ctrl</kbd>+<kbd>u</kbd>, **zsh:** <kbd>Alt</kbd>+<kbd>w</kbd>: cuts everything before
|
|
- **zsh:** <kbd>Ctrl</kbd>+<kbd>u</kbd>: cuts the entire command *(In bash you can combine <kbd>Ctrl</kbd>+<kbd>u</kbd> , <kbd>Ctrl</kbd>+<kbd>k</kbd>)*
|
|
- <kbd>Ctrl</kbd>+<kbd>y</kbd>: paste characters previously cut with any **Cut command**. *In bash you can chain **cut commands**, and <kbd>Ctrl</kbd>+<kbd>y</kbd> will paste them all.*
|
|
|
|
|
|
## Move cursor
|
|
- <kbd>Ctrl</kbd>+<kbd>left</kbd>: move to last word
|
|
- <kbd>Ctrl</kbd>+<kbd>right</kbd>: move to next word
|
|
- <kbd>home</kbd> or <kbd>Ctrl</kbd>+<kbd>a</kbd>: move to start of command
|
|
- <kbd>end</kbd> or <kbd>Ctrl</kbd>+<kbd>e</kbd>: move to end of command
|
|
|
|
|
|
## Other
|
|
- <kbd>Ctrl</kbd>+<kbd>_</kbd>: undo last edit *(very useful when exceeding <kbd>Ctrl</kbd>+<kbd>w</kbd>)*
|
|
|
|
# To see all shortcuts available
|
|
- **bash:** `bind -lp`
|
|
- **zsh:** `bindkey -L`
|
|
|
|
# Other examples
|
|
|
|
## Common usecases
|
|
Let's consider the last command to be:
|
|
|
|
mv foo bar
|
|
|
|
<kbd>up</kbd> , <kbd>Ctrl</kbd>+<kbd>w</kbd>: last command without the last word = `mv foo`
|
|
|
|
<kbd>Alt</kbd>+<kbd>0</kbd>+<kbd>.</kbd>: first argument of last command = `mv`
|
|
|
|
# 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 <kbd>Ctrl</kbd>+<kbd>w</kbd> 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 <kbd>Ctrl</kbd>+<kbd>w</kbd>, you'd have to repeat it 12 times.
|
|

It would be great to have similar shortcuts that only stops at the **space character** |
