NAME

----

hg - Mercurial source code management system

SYNOPSIS

--------

'hg' [-v -d -q -y] <command> [command options] [files]

DESCRIPTION

-----------

The hg(1) command provides a command line interface to the Mercurial system.

OPTIONS

-------

-R, --repository::

    repository root directory

--cwd::

    change working directory

-y, --noninteractive::

    do not prompt, assume 'yes' for any required answers

-q, --quiet::

    suppress output

-v, --verbose::

    enable additional output

--debug::

    enable debugging output

--traceback::

    print traceback on exception

--time::

    time how long the command takes

--profile::

    print command execution profile

--version::

    output version information and exit

-h, --help::

    display help and exit

COMMAND ELEMENTS

----------------

files ...::

    indicates one or more filename or relative path filenames; see

    "FILE NAME PATTERNS" for information on pattern matching

path::

    indicates a path on the local machine

revision::

    indicates a changeset which can be specified as a changeset revision

    number, a tag, or a unique substring of the changeset hash value

repository path::

    either the pathname of a local repository or the URI of a remote

    repository.  There are two available URI protocols, http:// which is

    fast and the old-http:// protocol which is much slower but does not

    require a special server on the web host.

COMMANDS

--------

add [options] [files ...]::

    Schedule files to be version controlled and added to the repository.

    The files will be added to the repository at the next commit.

    If no names are given, add all files in the current directory and

    its subdirectories.

addremove [options] [files ...]::

    Add all new files and remove all missing files from the repository.

    New files are ignored if they match any of the patterns in .hgignore. As

    with add, these changes take effect at the next commit.

    List changes in files, showing the revision id responsible for each line

    This command is useful to discover who did a change or when a change took

    place.

    Without the -a option, annotate will avoid processing files it

    detects as binary. With -a, annotate will generate an annotation

    anyway, probably with undesirable results.

    options:

    -a, --text            treat all files as text

    -I, --include <pat>   include names matching the given patterns

    -X, --exclude <pat>   exclude names matching the given patterns

    -r, --revision <rev>  annotate the specified revision

    -u, --user            list the author

    -c, --changeset       list the changeset

    -n, --number          list the revision number (default)

bundle <file> <other>::

    (EXPERIMENTAL)

    Generate a compressed changegroup file collecting all changesets

    not found in the other repository.

    This file can then be transferred using conventional means and

    applied to another repository with the unbundle command. This is

    useful when native push and pull are not available or when

    exporting an entire repository is undesirable. The standard file

    extension is ".hg".

    Unlike import/export, this exactly preserves all changeset

    contents including permissions, rename data, and revision history.

cat [options] <file ...>::

    Print the specified files as they were at the given revision.

    If no revision is given then the tip is used.

    Output may be to a file, in which case the name of the file is

    given using a format string.  The formatting rules are the same as

    for the export command, with the following additions:

    %s   basename of file being printed

    %d   dirname of file being printed, or '.' if in repo root

    %p   root-relative path name of file being printed

    options:

    -I, --include <pat>       include names matching the given patterns

    -X, --exclude <pat>       exclude names matching the given patterns

    -o, --output <filespec>   print output to file with formatted name

    -r, --rev <rev>           print the given revision

clone [options] <source> [dest]::

    Create a copy of an existing repository in a new directory.

    If no destination directory name is specified, it defaults to the

    basename of the source.

    The location of the source is added to the new repository's

    .hg/hgrc file, as the default to be used for future pulls.

    For efficiency, hardlinks are used for cloning whenever the source

    and destination are on the same filesystem.  Some filesystems,

    such as AFS, implement hardlinking incorrectly, but do not report

    errors.  In these cases, use the --pull option to avoid

    hardlinking.

    options:

    -U, --noupdate   do not update the new working directory

    --pull           use pull protocol to copy metadata

    -e, --ssh        specify ssh command to use

    --remotecmd      specify hg command to run on the remote side

commit [options] [files...]::

    Commit changes to the given files into the repository.

    If a list of files is omitted, all changes reported by "hg status"

    from the root of the repository will be commited.

    The HGEDITOR or EDITOR environment variables are used to start an

    editor to add a commit comment.

    Options:

    -A, --addremove       run addremove during commit

    -I, --include <pat>   include names matching the given patterns

    -X, --exclude <pat>   exclude names matching the given patterns

    -m, --message <text>  use <text> as commit message

    -l, --logfile <file>  read the commit message from <file>

    -d, --date <datecode> record datecode as commit date

    -u, --user <user>     record user as commiter

    aliases: ci

copy <source ...> <dest>::

    Mark dest as having copies of source files.  If dest is a

    directory, copies are put in that directory.  If dest is a file,

    there can only be one source.

    By default, this command copies the contents of files as they

    stand in the working directory.  If invoked with --after, the

    operation is recorded, but no copying is performed.

    This command takes effect in the next commit.

    NOTE: This command should be treated as experimental. While it

    should properly record copied files, this information is not yet

    fully used by merge, nor fully reported by log.

    Options:

    -A, --after           record a copy that has already occurred

    -I, --include <pat>   include names matching the given patterns

    -X, --exclude <pat>   exclude names matching the given patterns

    -f, --force           forcibly copy over an existing managed file

    aliases: cp

diff [-a] [-r revision] [-r revision] [files ...]::

    Show differences between revisions for the specified files.

    Differences between files are shown using the unified diff format.

    When two revision arguments are given, then changes are shown

    between those revisions. If only one revision is specified then

    that revision is compared to the working directory, and, when no

    revisions are specified, the working directory files are compared

    to its parent.

    Without the -a option, diff will avoid generating diffs of files

    it detects as binary. With -a, diff will generate a diff anyway,

    probably with undesirable results.

    options:

    -a, --text           treat all files as text

    -I, --include <pat>  include names matching the given patterns

    -X, --exclude <pat>  exclude names matching the given patterns

export [-o filespec] [revision] ...::

    Print the changeset header and diffs for one or more revisions.

    The information shown in the changeset header is: author,

    changeset hash, parent and commit comment.

    Output may be to a file, in which case the name of the file is

    given using a format string.  The formatting rules are as follows:

    %%   literal "%" character

    %H   changeset hash (40 bytes of hexadecimal)

    %N   number of patches being generated

    %R   changeset revision number

    %b   basename of the exporting repository

    %h   short-form changeset hash (12 bytes of hexadecimal)

    %n   zero-padded sequence number, starting at 1

    %r   zero-padded changeset revision number

    Without the -a option, export will avoid generating diffs of files

    it detects as binary. With -a, export will generate a diff anyway,

    probably with undesirable results.

    options:

    -a, --text                treat all files as text

    -o, --output <filespec>   print output to file with formatted name

forget [options] [files]::

    Undo an 'hg add' scheduled for the next commit.

    options:

    -I, --include <pat>  include names matching the given patterns

    -X, --exclude <pat>  exclude names matching the given patterns

grep [options] pattern [files]::

    Search revisions of files for a regular expression.

    This command behaves differently than Unix grep.  It only accepts

    Python/Perl regexps.  It searches repository history, not the

    working directory.  It always prints the revision number in which

    a match appears.

    By default, grep only prints output for the first revision of a

    file in which it finds a match.  To get it to print every revision

    that contains a change in match status ("-" for a match that

    becomes a non-match, or "+" for a non-match that becomes a match),

    use the --all flag.

    options:

    -0, --print0              end fields with NUL

    -I, --include <pat>       include names matching the given patterns

    -X, --exclude <pat>       exclude names matching the given patterns

        --all                 print all revisions that match

    -i, --ignore-case         ignore case when matching

    -l, --files-with-matches  print only filenames and revs that match

    -n, --line-number         print matching line numbers

    -r <rev>, --rev <rev>     search in given revision range

    -u, --user                print user who committed change

heads::

    Show all repository head changesets.

    Repository "heads" are changesets that don't have children

    changesets. They are where development generally takes place and

    are the usual targets for update and merge operations.

identify::

    Print a short summary of the current state of the repo.

    This summary identifies the repository state using one or two parent

    hash identifiers, followed by a "+" if there are uncommitted changes

    in the working directory, followed by a list of tags for this revision.

    aliases: id

import [-p <n> -b <base> -f] <patches>::

    Import a list of patches and commit them individually.

    If there are outstanding changes in the working directory, import

    will abort unless given the -f flag.

    If a patch looks like a mail message (its first line starts with

    "From " or looks like an RFC822 header), it will not be applied

    unless the -f option is used.  The importer neither parses nor

    discards mail headers, so use -f only to override the "mailness"

    safety check, not to import a real mail message.

    options:

    -p, --strip <n>   directory strip option for patch. This has the same

                      meaning as the corresponding patch option

    -b <path>         base directory to read patches from

    -f, --force       skip check for outstanding uncommitted changes

    aliases: patch

incoming [-p] [source]::

    Show new changesets found in the specified repo or the default

    pull repo. These are the changesets that would be pulled if a pull

    was requested.

    Currently only local repositories are supported.

    options:

    -p, --patch           show patch

    aliases: in

init [dest]::

    Initialize a new repository in the given directory.  If the given

    directory does not exist, it is created.

    If no directory is given, the current directory is used.

locate [options] [files]::

    Print all files under Mercurial control whose names match the

    given patterns.

    This command searches the current directory and its

    subdirectories.  To search an entire repository, move to the root

    of the repository.

    If no patterns are given to match, this command prints all file

    names.

    If you want to feed the output of this command into the "xargs"

    command, use the "-0" option to both this command and "xargs".

    This will avoid the problem of "xargs" treating single filenames

    that contain white space as multiple filenames.

    options:

    -0, --print0         end filenames with NUL, for use with xargs

    -f, --fullpath       print complete paths from the filesystem root

    -I, --include <pat>  include names matching the given patterns

    -r, --rev <rev>      search the repository as it stood at rev

    -X, --exclude <pat>  exclude names matching the given patterns

log [-r revision ...] [-p] [files]::

    Print the revision history of the specified files or the entire project.

    By default this command outputs: changeset id and hash, tags,

    parents, user, date and time, and a summary for each commit. The

    -v switch adds some more detail, such as changed files, manifest

    hashes or message signatures.

    options:

    -I, --include <pat>   include names matching the given patterns

    -X, --exclude <pat>   exclude names matching the given patterns

    -r, --rev <A>         show the specified revision or range

    -p, --patch           show patch

    aliases: history

manifest [revision]::

    Print a list of version controlled files for the given revision.

    The manifest is the list of files being version controlled. If no revision

    is given then the tip is used.

outgoing [-p] [dest]::

    Show changesets not found in the specified destination repo or the

    default push repo. These are the changesets that would be pushed

    if a push was requested.

    options:

    -p, --patch           show patch

    aliases: out

parents::

    Print the working directory's parent revisions.

paths [NAME]::

    Show definition of symbolic path name NAME. If no name is given, show

    definition of available names.

    Path names are defined in the [paths] section of /etc/mercurial/hgrc

    and $HOME/.hgrc.  If run inside a repository, .hg/hgrc is used, too.

pull <repository path>::

    Pull changes from a remote repository to a local one.

    This finds all changes from the repository at the specified path

    or URL and adds them to the local repository. By default, this

    does not update the copy of the project in the working directory.

    Valid URLs are of the form:

      local/filesystem/path

      http://[user@]host[:port][/path]

      https://[user@]host[:port][/path]

      ssh://[user@]host[:port][/path]

    SSH requires an accessible shell account on the destination machine

    and a copy of hg in the remote path.  With SSH, paths are relative

    to the remote user's home directory by default; use two slashes at

    the start of a path to specify it as relative to the filesystem root.

    options:

    -u, --update   update the working directory to tip after pull

    -e, --ssh    specify ssh command to use

    --remotecmd  specify hg command to run on the remote side

push <destination>::

    Push changes from the local repository to the given destination.

    This is the symmetrical operation for pull. It helps to move

    changes from the current repository to a different one. If the

    destination is local this is identical to a pull in that directory

    from the current one.

    By default, push will refuse to run if it detects the result would

    increase the number of remote heads. This generally indicates the

    the client has forgotten to sync and merge before pushing.

    Valid URLs are of the form:

      local/filesystem/path

      ssh://[user@]host[:port][/path]

    SSH requires an accessible shell account on the destination

    machine and a copy of hg in the remote path.

    options:

    -f, --force  force update

    -e, --ssh    specify ssh command to use

    --remotecmd  specify hg command to run on the remote side

rawcommit [-p -d -u -F -m -l]::

    Lowlevel commit, for use in helper scripts.

    This command is not intended to be used by normal users, as it is

    primarily useful for importing from other SCMs.

recover::

    Recover from an interrupted commit or pull.

    This command tries to fix the repository status after an interrupted

    operation. It should only be necessary when Mercurial suggests it.

remove [options] [files ...]::

    Schedule the indicated files for removal from the repository.

    This command schedules the files to be removed at the next commit.

    This only removes files from the current branch, not from the

    entire project history.  If the files still exist in the working

    directory, they will be deleted from it.

    aliases: rm

rename <source ...> <dest>::

    Mark dest as copies of sources; mark sources for deletion.  If

    dest is a directory, copies are put in that directory.  If dest is

    a file, there can only be one source.

    By default, this command copies the contents of files as they

    stand in the working directory.  If invoked with --after, the

    operation is recorded, but no copying is performed.
