The command "git apply --reverse ${filename}" is used in Git to remove the changes introduced by a patch.
Here's an explanation of the different elements of the command:
-
"git apply": The "git apply" command is used to apply a patch to the current repository. It takes a patch file as input and applies the changes specified in the patch to the repository.
-
"--reverse": The "--reverse" option is used to reverse the changes introduced by a patch. It undoes the modifications made by a patch file, effectively removing the changes from the repository.
-
"${filename}": This represents the name of the patch file that you want to reverse apply. You need to specify the actual filename or path to the patch file that you want to reverse apply.
So, when you run the command "git apply --reverse ${filename}", Git will take the specified patch file and undo the changes introduced by it, effectively removing those changes from the repository.
