1003 usage: $P [options] patchfile
1004 $P [options] -f file|directory
1007 MAINTAINER field selection options:
1008 --email => print email address(es) if any
1009 --git => include recent git \*-by: signers
1010 --git-all-signature-types => include signers regardless of signature type
1011 or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
1012 --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
1013 --git-chief-penguins => include ${penguin_chiefs}
1014 --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
1015 --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
1016 --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
1017 --git-blame => use git blame to find modified commits for patch or file
1018 --git-blame-signatures => when used with --git-blame, also include all commit signers
1019 --git-since => git history to use (default: $email_git_since)
1020 --hg-since => hg history to use (default: $email_hg_since)
1021 --interactive => display a menu (mostly useful if used with the --git option)
1022 --m => include maintainer(s) if any
1023 --r => include reviewer(s) if any
1024 --n => include name 'Full Name <addr\@domain.tld>'
1025 --l => include list(s) if any
1026 --s => include subscriber only list(s) if any
1027 --remove-duplicates => minimize duplicate email names/addresses
1028 --roles => show roles (status:subsystem, git-signer, list, etc...)
1029 --rolestats => show roles and statistics (commits/total_commits, %)
1030 --file-emails => add email addresses found in -f file (default: 0 (off))
1031 --scm => print SCM tree(s) if any
1032 --status => print status if any
1033 --subsystem => print subsystem name if any
1034 --web => print website(s) if any
1036 Output type options:
1037 --separator [, ] => separator for multiple entries on 1 line
1038 using --separator also sets --nomultiline if --separator is not [, ]
1039 --multiline => print 1 entry per line
1042 --pattern-depth => Number of pattern directory traversals (default: 0 (all))
1043 --keywords => scan patch for keywords (default: $keywords)
1044 --sections => print all of the subsystem sections with pattern matches
1045 --letters => print all matching 'letter' types from all matching sections
1046 --mailmap => use .mailmap file (default: $email_use_mailmap)
1047 --no-tree => run without a kernel tree
1048 --self-test => show potential issues with MAINTAINERS file content
1049 --version => show version
1050 --help => show this help information
1053 [--email --tree --nogit --git-fallback --m --r --n --l --multiline
1054 --pattern-depth=0 --remove-duplicates --rolestats]
1057 Using "-f directory" may give unexpected results:
1058 Used with "--git", git signators for _all_ files in and below
1059 directory are examined as git recurses directories.
1060 Any specified X: (exclude) pattern matches are _not_ ignored.
1061 Used with "--nogit", directory is used as a pattern match,
1062 no individual file within the directory or subdirectory
1064 Used with "--git-blame", does not iterate all files in directory
1065 Using "--git-blame" is slow and may add old committers and authors
1066 that are no longer active maintainers to the output.
1067 Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
1068 other automated tools that expect only ["name"] <email address>
1069 may not work because of additional output after <email address>.
1070 Using "--rolestats" and "--git-blame" shows the #/total=% commits,
1071 not the percentage of the entire file authored. # of commits is
1072 not a good measure of amount of code authored. 1 major commit may
1073 contain a thousand lines, 5 trivial commits may modify a single line.
1074 If git is not installed, but mercurial (hg) is installed and an .hg
1075 repository exists, the following options apply to mercurial:
1077 --git-min-signatures, --git-max-maintainers, --git-min-percent, and
1079 Use --hg-since not --git-since to control date selection
1080 File ".get_maintainer.conf", if it exists in the linux kernel source root
1081 directory, can change whatever get_maintainer defaults are desired.
1082 Entries in this file can be any command line argument.
1083 This file is prepended to any additional command line arguments.
1084 Multiple lines and # comments are allowed.
1085 Most options have both positive and negative forms.
1086 The negative forms for --<foo> are --no<foo> and --no-<foo>.
