This command applies a patch file to a given input file and saves the updated version to an output file. Here's a breakdown of each component:
patch
: It is a command-line tool used for applying patches to files.${path-to-input_file}
: It should be replaced with the actual path to the input file, which is the file you want to modify.-o
: It is an option flag followed by${path-to-output_file}
, which specifies the path to the output file. The output file will contain the modified version of the input file after the patch is applied.${patch-diff}
: It should be replaced with the actual path to the patch diff file, which is the file that contains the changes to be applied to the input file. The patch diff file usually follows the unified diff format, which shows the differences between the original and modified versions of a file.
By using the <
symbol, the patch command reads the contents of the patch diff file as input, which specifies the modifications to be applied to the input file. The command then processes the patch diff and applies the changes to the input file, resulting in an updated version of the file that is saved to the output file specified with the -o
flag.
