patch: Apply a patch using a diff file (filenames must be included in the diff file).
$ patch < ${patch-diff}
try on your machine
The command "patch < ${patch-diff}" is used to apply a patch to a file or set of files.
Here's how it works:
-
The "patch" command is used to apply changes from a patch file to the corresponding files.
- "patch" compares the original file(s) with the patched file(s) described in the patch file and applies the necessary changes.
-
The "<" symbol indicates that the patch file should be used as input for the patch command.
- It redirects the contents of the patch file as input to the "patch" command.
-
${patch-diff} is a placeholder for the actual filename or path of the patch file.
- The dollar sign and curly braces indicate that this is a variable. The variable name is "patch-diff".
- The variable holds the name or location of the patch file to be used in the patch command.
Overall, this command applies the changes specified in the patch file to the corresponding file(s) mentioned within the patch file. The resulting patched file(s) will contain the changes specified in the patch.
