replacing last command and execute it

For example
$ echo "hello world world world"                   
hello world world world
If you want to replace world with universe you can do
# If you use ZSH you can press `tab` at the end of the line and it will replace
# the whole line with the actuall command
$ ^world^universe
$ echo "hello universe world world"
As you can see, it only replace the first matching word.
If you want it to replace the whole match:
# zsh
$ ^world^universe^:G
​
# bash
$^world^universe^&
Don't use it in production
I tend to use fc command which allow me to edit the command in my editor first

repeat content of text x time
