 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
 -------
 
 --debug, -d::
     enable debugging output
 
 --quiet, -q::
     suppress output
 
 --verbose, -v::
     enable additional output
 
 --noninteractive, -y::
     do not prompt, assume 'yes' for any required answers
 
 COMMAND ELEMENTS
 ----------------
 
 files ...::
     indicates one or more filename or relative path filenames
 
 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 [files ...]::
     Schedule files to be version controlled and added to the repository.
     
     The files will be added to the repository at the next commit.
 
 addremove::
     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.
 
 annotate [-r <rev> -u -n -c] [files ...]::
     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.
     
     options:
     -r, --revision <rev>  annotate the specified revision
     -u, --user            list the author
     -c, --changeset       list the changeset
     -n, --number          list the revision number (default)
 
 cat <file> [revision]::
     Output to stdout the given revision for the specified file.
 
     If no revision is given then the tip is used.
 
 clone [-U] <source> [dest]::
     Create a copy of an existing repository in a new directory.
 
     If the destination directory is specified but doesn't exist, it is
     created. If no destination directory is specified, it defaults to the
     current directory.
 
     The source is added to the new repository's .hg/hgrc file to be used in
     future pulls.
 
     For efficiency, hardlinks are used for cloning whenever the
     source and destination are on the same filesystem.
 
     options:
-    -U, --no-update   do not update the new working directory
+    -U, --noupdate   do not update the new working directory
 
 commit [-A -t -l <file> -t <text> -u <user> -d <datecode>] [files...]::
     Commit changes to the given files into the repository.
     
     If a list of files is omitted, all changes reported by "hg status"
     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
     -t, --text <text>     use <text> as commit message
     -l, --logfile <file>  show the commit message for the given file
     -d, --date <datecode> record datecode as commit date
     -u, --user <user>     record user as commiter
 
     aliases: ci
 
 copy <source> <dest>::
     Mark <dest> file as a copy or rename of a <source> one
     
     This command takes effect for the next commit.
 
 diff [-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.
 
 export [revision]::
     Print the changeset header and diffs for a particular revision.
 
     The information shown in the changeset header is: author, changeset hash,
     parent and commit comment.
 
 forget [files]::
     Undo an 'hg add' scheduled for the next commit.
 
 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.
 
 history::
     Print a log of the revision history of the repository.
     
     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.
 
     To display the history of a given file, see the log command.
 
 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> -q] <patches>::
     Import a list of patches and commit them individually.
 
     options:
     -p, --strip <n>   directory strip option for patch. This has the same
                       meaning as the correnponding patch option
     -b <path>         base directory to read patches from
 
     aliases: patch
 
 init::
     Initialize a new repository in the current directory.
 
 log <file>::
     Print the revision history of the specified file.
 
     To display the revision history for the whole repository, use the history
     command.
 
 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.
 
 parents::
     Print the working directory's parent revisions.
 
 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.
 
     options:
     -u, --update   update the working directory to tip after pull
 
 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.
 
     The other currently available push method is SSH. This requires an
     accessible shell account on the destination machine and a copy of
     hg in the remote path. Destinations are specified in the following
     form:
 
       ssh://[user@]host[:port]/path
 
 rawcommit [-p -d -u -F -t -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 [files ...]::
     Schedule the indicated files for removal from the repository.
     
     This command shedules the files to be removed at the next commit.
     This only removes files from the current branch, not from the
     entire project history.
 
     aliases: rm
 
 root::
     Print the root directory of the current repository.
 
 serve [-a addr -n name -p port -t templatedir]::
     Start a local HTTP repository browser and pull server.
 
     options:
     -a, --address <addr> address to use
     -p, --port <n>       port to use (default: 8000)
     -n, --name <name>    name to show in web pages (default: working dir)
     -t, --templatedir <path> web templates to use
 
 status::
     Show changed files in the working directory.
 
     The codes used to show the status of files are:
     
     C = changed
     A = added
     R = removed
     ? = not tracked
 
 tag [-t <text> -d <datecode> -u <user>] <name> [revision]::
     Name a particular revision using <name>.
     
     Tags are used to name particular revisions of the repository and are
     very useful to compare different revision, to go back to significant
     earlier versions or to mark branch points as releases, etc.
     
     If no revision is given, the tip is used.
 
     To facilitate version control, distribution, and merging of tags,
     they are stored as a file named ".hgtags" which is managed
     similarly to other project files and can be hand-edited if
     necessary.
 
     options:
     -t, --text <text>     message for tag commit log entry
     -d, --date <datecode> datecode for commit
     -u, --user <user>     user for commit
 
     Note: Mercurial also has support for "local tags" that are not
     version-controlled or distributed which are stored in the .hg/hgrc
     file.
 
 tags::
     List the repository tags.
 
     This lists both regular and local tags.
 
 tip::
     Show the tip revision.
 
 undo::
     Undo the last commit or pull transaction.
 
 update [-m -C] [revision]::
     Update the working directory to the specified revision.
 
     By default, update will refuse to run if doing so would require
     merging or discarding local changes.
 
     With the -m option, a merge will be performed.
 
     With the -C option, local changes will be lost.
     
     options:
     -m, --merge       allow merging of branches
     -C, --clean       overwrite locally modified files
 
     aliases: up checkout co
 
 verify::
     Verify the integrity of the current repository.
 
     This will perform an extensive check of the repository's
     integrity, validating the hashes and checksums of each entry in
     the changelog, manifest, and tracked files, as well as the
     integrity of their crosslinks and indices.
 
 
 ENVIRONMENT VARIABLES
 ---------------------
 
 HGEDITOR::
     This is the name of the editor to use when committing. Defaults to the
     value of EDITOR.
 
 HGMERGE::
     An executable to use for resolving merge conflicts. The program
     will be executed with three arguments: local file, remote file,
     ancestor file.
 
     The default program is "hgmerge", which is a shell script provided
     by Mercurial with some sensible defaults.
 
 HGUSER::
     This is the string used for the author of a commit.
 
 EMAIL::
     If HGUSER is not set, this will be used as the author for a commit.
 
 LOGNAME::
     If neither HGUSER nor EMAIL is set, LOGNAME will be used (with
     '@hostname' appended) as the author value for a commit.
 
 EDITOR::
     This is the name of the editor used in the hgmerge script. It will be
     used for commit messages if HGEDITOR isn't set. Defaults to 'vi'.
 
 PYTHONPATH::
     This is used by Python to find imported modules and may need to be set
     appropriately if Mercurial is not installed system-wide.
 
 FILES
 -----
  .hgignore::
     This file contains regular expressions (one per line) that describe file
     names that should be ignored by hg.
 
  .hgtags::
     This file contains changeset hash values and text tag names (one of each
     seperated by spaces) that correspond to tagged versions of the repository
     contents.
 
  $HOME/.hgrc, .hg/hgrc::
     This file contains defaults and configuration. Values in .hg/hgrc
     override those in .hgrc.
 
 NAMED REPOSITORIES
 ------------------
 
 To give symbolic names to a repository, create a section in .hgrc
 or .hg/hgrc containing assignments of names to paths. Example:
 
 -----------------
 [paths]
 hg = http://selenic.com/hg
 tah = http://hg.intevation.org/mercurial-tah/
 -----------------
 
 
 LOCAL TAGS
 ----------
 
 To create tags that are local to the repository and not distributed or
 version-controlled, create an hgrc section like the following:
 
 ----------------
 [tags]
 working = 2dcced388cab3677a8f543c3c47a0ad34ac9d435
 tested = 12e0fdbc57a0be78f0e817fd1d170a3615cd35da
 ----------------
 
 
 HOOKS
 -----
 
 Mercurial supports a set of 'hook', commands that get automatically
 executed by various actions such as starting or finishing a commit. To
 specify a hook, simply create an hgrc section like the following:
 
 -----------------
 [hooks]
 precommit = echo "this hook gets executed immediately before a commit"
 commit = hg export $NODE | mail -s "new commit $NODE" commit-list
 -----------------
 
 
 NON_TRANSPARENT PROXY SUPPORT
 -----------------------------
 
 To access a Mercurial repository through a proxy, create a file
 $HOME/.hgrc in the following format:
 
 --------------
 [http_proxy]
 host=myproxy:8080
 user=<username>
 passwd=<password>
 no=<localhost1>,<localhost2>,<localhost3>,...
 --------------
 
 "user" and "passwd" fields are used for authenticating proxies, "no" is a
 comma-separated list of local host names to not proxy.
 
 BUGS
 ----
 Probably lots, please post them to the mailing list (See Resources below)
 when you find them.

     there is a linear relationship between the current version and the
     requested version, the result is the requested version.
 
     Otherwise the result is a merge between the contents of the
     current working directory and the requested version. Files that
     changed between either parent are marked as changed for the next
     commit and a commit must be performed before any further updates
     are allowed.
