- -h no filename headers (like grep), only the listing.
- -l no listing (like grep), only the filename headers.
- -i Invert: for each patched file list which patch files patch it.
- -c Categorise the patch and sort by category (perl specific).
- -m print formatted Meta-information (Subject,From,Msg-ID etc).
- -p N strip N levels of directory Prefix (like patch), else automatic.
- -v more verbose (-d for noisy debugging).
- -n give a count of the number of patches applied to a file if >1.
- -f F only list patches which patch files matching regexp F
- (F has \$ appended unless it contains a /).
- -e Expect patched files to Exist (relative to current directory)
- Will print warnings for files which don't. Also affects -4 option.
- - Read patch from STDIN
- other options for special uses:
- -I just gather and display summary Information about the patches.
- -4 write to stdout the PerForce commands to prepare for patching.
- -5 like -4 but add "|| exit 1" after each command
- -M T Like -m but only output listed meta tags (eg -M 'Title From')
- -W N set wrap width to N (defaults to 70, use 0 for no wrap)
- -X list patchfiles that may clash (i.e. patch the same file)
