NAME
       copyright-update - Update Copyright information in files


SYNOPSIS
         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.


OPTIONS
   Run options
       -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 environment, 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 licenses 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 current 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.

   Miscellaneous options
       -h, --help
           Display help.

       --help-exclude
           Display default values used to exclude paths and files.

       --help-html
           Display help in HTML format.

       --help-man
           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:

          copyright-update *

       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.


ENVIRONMENT
       EMAIL
           In the form "firstname.lastname@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-]+@':

               address@example.com            Not used, not in form First.Last
               +------ +----------

               mr.first.lastname@example.com  Not used, likewise
               +---------------- +----------
               |                 |
               Localpart         Domain part

       NAME
           In the form "Firstname Lastname". If set, the value is used in option --auto.
