diffutils: Invoking patch
1
1 15 Invoking 'patch'
1 *******************
1
1 Normally 'patch' is invoked like this:
1
1 patch <PATCHFILE
1
1 The full format for invoking 'patch' is:
1
1 patch OPTIONS... [ORIGFILE [PATCHFILE]]
1
1 You can also specify where to read the patch from with the '-i
1 PATCHFILE' or '--input=PATCHFILE' option. If you do not specify
1 PATCHFILE, or if PATCHFILE is '-', 'patch' reads the patch (that is, the
1 'diff' output) from the standard input.
1
1 If you do not specify an input file on the command line, 'patch'
1 tries to intuit from the "leading text" (any text in the patch that
11 comes before the 'diff' output) which file to edit. ⇒Multiple
Patches.
1
1 By default, 'patch' replaces the original input file with the patched
1 version, possibly after renaming the original file into a backup file
1 (⇒Backup Names, for a description of how 'patch' names backup
1 files). You can also specify where to put the output with the '-o FILE'
1 or '--output=FILE' option; however, do not use this option if FILE is
1 one of the input files.
