Occasionally I use the bash command to replace string in previous command:
^foo^bar Today I wanted to make the replacement in the following line for replacing all occurrences of checkbox with `radio:
$ git mv _product_checkbox_buttons.html.erb _product_checkbox_button.html.erb $ ^checkbox^radio git mv _product_radio_buttons.html.erb _product_checkbox_button.html.erb So it only replaces the first occurrence. How do I make it replace all occurrences?

When you do foo= bar then you are assigning an empty string to the environment variable foo and then execute the command bar . It can be used to pass environment variables to a new execution.
The terms foobar (/ˈfuːbɑːr/), foo, bar, baz, and others are used as metasyntactic variables and placeholder names in computer programming or computer-related documentation.

man bash says ^old^new is equivalent to !!:s/old/new/. You want !!:gs/old/new/ to globally replace.

An easy way of doing this would be:
fc -s checkbox=radio I have an alias r defined in my .bashrc:
alias r='fc -s' Then what you want to do becomes:
r checkbox=radio See my answer to "hidden features of bash" question for details.
