APPLYPATCH(1) User Contributed Perl Documentation APPLYPATCH(1)NAMEapplypatch - apply 'makepatch' generated script to update a source tree
SYNOPSISapplypatch [ options ] patch-kit
DESCRIPTION
Applypatch applies a patch kit as generated by the makepatch program.
It performs the following actions:
· First, it will extensively verify that the patch kit is complete
and did not get corrupted during transfer.
· Then it will apply some heuristics to verify that the directory in
which the patch will be applied does indeed contain the expected
sources.
If a corruption or verification error is detected, applypatch exits
without making changes.
· If the kit is okay, and the directory seems to be the right one: it
creates new files and directories as necessary.
· Then it runs the patch program to apply the patch to the source
files.
· Upon completion, obsolete files, directories and .orig files are
removed, file modes of new files are set, and the timestamps of all
patched files are adjusted.
Applypatch arguments
Applypatch takes one argument, the name of the patch kit as generated
by makepatch. If no name is specified, the patch kit is read from
standard input.
Applypatch options
Options are matched case insensitive, and may be abbreviated to
uniqueness.
-directory dir
The name of the source directory to be patched.
-check
Perform the checks on the patch kit and patch directory, but do not
make any changes.
-force
Force continuation of the patch process even when corruption or
verification errors are detected. This is very dangerous!
-retain
Do not remove patch backup files (with extension ".orig") upon
completion.
-patch cmd
The patch command to be used. Default is ""patch -p0 -N"".
Additionally, a ""-s"" will be added unless option -verbose was
specified.
-verbose
This option will cause applypatch and the patch program to emit
verbose progress information.
-quiet
This option will cause applypatch and the patch program to emit no
progress information, only error messages.
Environment variables
SIMPLE_BACKUP_SUFFIX
The suffix used by (some versions of?) patch to back up the
originals of patched files. Upon completion, these files are
removed by applypatch unless the option -retain was specified.
Default value if "".orig"".
