применить изменения к файлам (apply changes to files)
Описание (Description)
The patch utility shall read a source (patch) file containing any
of four forms of difference (diff) listings produced by the diff
utility (normal, copied context, unified context, or in the style
of ed) and apply those differences to a file. By default, patch
shall read from the standard input.
The patch utility shall attempt to determine the type of the diff
listing, unless overruled by a -c, -e, -n, or -u option.
If the patch file contains more than one patch, patch shall
attempt to apply each of them as if they came from separate patch
files. (In this case, the application shall ensure that the name
of the patch file is determinable for each diff listing.)
