NAME¶copyright-update - Update Copyright information in files
copyright-update [options] FILE [FILE ...] copyright-update [options] --recursive PATH [PATH ...]
DESCRIPTION¶Update the copyright information in set of files, possibly recursively, matching content criteria. The updating affects copyright year, GPL address information etc.
The line must have word "Copyright", a space, three characters '(C)' (or a U+00A9 UTF copyright sign), a space, and the range of years. Varying amount of spaces and tabs are permitted, but there must be no spaces around the dash-character in YEAR-YEAR. Examples:
A whitespace, or multiple, required | | No space between years | | | Copyright (C) YYYY-YYYY Copyright: (C) YYYY-YYYY | A colon is optional
By default certain files and paths are always ignored; like version control directories, backups files, object files and binary files according to Perl's "-T" file test. Run program with option --help-exclude to see exclude path list.
- -a, --auto
- In automatic mode, the author's name is read from environment variable
NAME and only lines matching 'Copyright.*$NAME' are affected. If NAME is
not set, read information from EMAIL.
If neither NAME nor EMAIL exists in evenvironemt, or if their values are not in a recognizable formats (see section ENVIRONMENT), this options does nothing.
This option effectively tries to preset value for the --line option.
- -c, --code
- Preset --include to match common code files: .c, .h, .cc, .hh, .cpp, .c++, .hpp, .C, .pl, .py, .sh and .rb
- -d, --debug LEVEL
- Turn on debug. Level can be in range 0-10.
- -f, --fsf-address
- Change License paragraphs that refer to FSF address. The FSF's current
recommendation is to redirect inquiries about licences to their URL.
Effectively replace paragraphs:

- -i, --include REGEXP
- Include files matching regexp. The match is done against whole path.
If this option is not supplied, every file is automatically included. The matches can be further filtered by using option --exclude.
This option can be used multiple times. See also option --code.
- -l, --line REGEXP
- Change only lines which match REGEXP. The match is case-insensitive.
- -r, --recursive
- Recursively search all directories given in command line.
- -R, --regexp REGEXP
- Change only files whose content matches REGEXP. The file is read in as a
one big string so that it's possible to match using Perl regular
expressions across the whole file. An example:
'(?smi)This.*multi.*line.*match'. See perlre(1) for more
information about 'smi' and other modifiers.
This option can be used as a preliminary Content criteria, to select files before --line option finds the correct Copyright lines.
- -t, --test, --dry-run
- Run in test mode. Show what would happen. No files are changed.
- -v, --verbose LEVEL
- Print informational messages. Increase numeric LEVEL for more verbosity.
- -x, --exclude REGEXP
- Ignore files matching regexp. The match is done against whole path. The
option can be used multiple times.
This option is applied after possible --include matches.
- -y, --year YEAR
- Update files using YEAR. Value must be four digits.
The default operation is to use currect year, so this option is not necessary in normal use. Use case: you plan to take a long holiday before year's end and want to update the next year's value beforehand.
- -Y, --no-year
- Disable updating year.
- -h, --help
- Display help.
- Display default values used to exclude paths and files.
- Display help in HTML format.
- Display help in manual page man(1) format.
- -V, --version
- Display contact and version information.
EXAMPLES¶The primary use is to update files to reflect current year; option --year is implicit:
To test what would happen:
copyright-update --verbose 1 --test *
Update only C-code file:
copyright-update --verbose 1 --include '\.[ch]$' --recursive .
It is possible to restrict updating files recursively to only those files whose content match regexp. Here, the lines affected are those that match --line regular expression.
copyright-update \ --regexp '(?i)Author:.*John.*Doe' \ --line '\bFoo\b' \ --ignore '\.(bak|bup|[~#]])$' \ --verbose 1 \ --year 2013 \ --test \ --recursive \ .
TROUBLESHOOTING¶See option --debug.
- In the form "email@example.com"; that is, without
the angles <>. If set, the value is used in option --auto
only if environment variable NAME is not set.
In order to find first and lastname, the localpart in email address must match case insensitive regexp '^[a-z-]+\.[a-z-]+@':
firstname.lastname@example.org Not used, not in form First.Last +------ +---------- email@example.com Not used, likewise +---------------- +---------- | | Localpart Domain part
- In the form "Firstname Lastname". If set, the value is used in option --auto.
EXIT STATUS¶Not defined.
DEPENDENCIES¶Uses only standard Perl modules.
BUGS AND LIMITATIONS¶The Copyright stanzas searched with option --fsf-address must be exactly like in the FSF recommendation in order for them to be noticed. See STANDARDS.
