zsh variable editing
Lets say I made a typo in an important environment variable and I wanted a quick fix, just to see if yes, that was indeed why my application wasn't working.
$ echo $RAILS_ENV > porduction # ^^^ YIKES ^^^
The Z shell has a builtin program called
vared that helps you edit an existing environment/shell variable.
$ vared RAILS_ENV porduction
Now you are in an editing context, you can edit the value with all your configured command line editing tools. Fix the error, hit RETURN, and you're good!Tweet
