The command line is great, but it can be inconvenient. I can't count the number of times I put in a command wrong, and either had to type it out again or use my mouse to clumsily highlight it so I could copy, paste, and fix it. Neither is convenient.
But there is a way to quickly change your last command! Using the
^ character, you can substitute one group of characters for another.
Let's say I accidently looked at the files of the
foo folder when I wanted to look at
In the below command, I write the string to target after the first
^ characters, and what to replace it with after the second
This will make the following command appear in my command line, waiting to be run again. I could manually change it if I wanted before running it again.
Just remember only the first instance of the string is replaced, not each one.
