HG(1) ===== Matt Mackall NAME ---- hg - Mercurial source code management system SYNOPSIS -------- 'hg' [-v -d -q -y] [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; 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. annotate [-r -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: -I, --include include directories matching the given patterns -X, --exclude exclude directories matching the given patterns -r, --revision annotate the specified revision -u, --user list the author -c, --changeset list the changeset -n, --number list the revision number (default) cat [revision]:: Output to stdout the given revision for the specified file. If no revision is given then the tip is used. clone [-U] [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 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, --noupdate do not update the new working directory commit [-A -t -l -m -u -d ] [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 -m, --message use as commit message -l, --logfile show the commit message for the given file -d, --date record datecode as commit date -u, --user record user as commiter aliases: ci copy :: Mark file as a copy or rename of a 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. options: -I, --include include directories matching the given patterns -X, --exclude exclude directories 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 Options: -o, --output print output to file with formatted named 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. 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 -b -q] :: Import a list of patches and commit them individually. options: -p, --strip directory strip option for patch. This has the same meaning as the correnponding patch option -b base directory to read patches from aliases: patch init:: Initialize a new repository in the current directory. 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 file names. options: -0, --print0 end filenames with NUL, for use with xargs -f, --fullpath print complete paths from the filesystem root -I, --include include directories matching the given patterns -r, --rev search the repository as it stood at rev -X, --exclude exclude directories matching the given patterns log [-r revision ...] [-p] [file]:: Print the revision history of the specified file 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: -r, --rev , ... When a revision argument is given, only this file or changelog revision is displayed. With two revision arguments all revisions in this range are listed. Additional revision arguments may be given repeating the above cycle. -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. parents:: Print the working directory's parent revisions. pull :: 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 :: 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 -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 [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 revert [names ...]:: Revert any uncommitted modifications made to the named files or directories. This restores the contents of the affected files to an unmodified state. If a file has been deleted, it is recreated. If the executable mode of a file was changed, it is reset. If a directory is given, all files in that directory and its subdirectories are reverted. If no arguments are given, all files in the current directory and its subdirectories are reverted. options: -r, --rev revision to revert to -n, --nonrecursive do not recurse into subdirectories root:: Print the root directory of the current repository. serve [options]:: Start a local HTTP repository browser and pull server. By default, the server logs accesses to stdout and errors to stderr. Use the "-A" and "-E" options to log to files. options: -A, --accesslog name of access log file to write to -E, --errorlog name of error log file to write to -a, --address address to use -p, --port port to use (default: 8000) -n, --name name to show in web pages (default: working dir) -t, --templatedir web templates to use status [options] [files]:: Show changed files in the working directory. If no names are given, all files are shown. Otherwise, only files matching the given names are shown. The codes used to show the status of files are: M = changed A = added R = removed ? = not tracked options: -I, --include include directories matching the given patterns -X, --exclude exclude directories matching the given patterns tag [-l -m -d -u ] [revision]:: Name a particular revision using . 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: -l, --local make the tag local -m, --message message for tag commit log entry -d, --date datecode for commit -u, --user user for commit Note: Local tags are not version-controlled or distributed and are stored in the .hg/localtags file. If there exists a local tag and a public tag with the same name, local tag is used. 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. Roll back the last pull or commit transaction on the repository, restoring the project to its earlier state. This command should be used with care. There is only one level of undo and there is no redo. This command is not intended for use on public repositories. Once a change is visible for pull by other users, undoing it locally is ineffective. 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. FILE NAME PATTERNS ------------------ Mercurial accepts several notations for identifying one or more file at a time. By default, Mercurial treats file names as shell-style extended glob patterns. Alternate pattern notations must be specified explicitly. To use a plain path name without any pattern matching, start a name with "path:". These path names must match completely, from the root of the current repository. To use an extended glob, start a name with "glob:". Globs are rooted at the current directory; a glob such as "*.c" will match files ending in ".c" in the current directory only. The supported glob syntax extensions are "**" to match any string across path separators, and "{a,b}" to mean "a or b". To use a Perl/Python regular expression, start a name with "re:". Regexp pattern matching is anchored at the root of the repository. Plain examples: path:foo/bar a name bar in a directory named foo in the root of the repository path:path:name a file or directory named "path:name" Glob examples: glob:*.c any name ending in ".c" in the current directory *.c any name ending in ".c" in the current directory **.c any name ending in ".c" in the current directory, or any subdirectory foo/*.c any name ending in ".c" in the directory foo foo/**.c any name ending in ".c" in the directory foo, or any subdirectory Regexp examples: re:.*\.c$ any name ending in ".c", anywhere in the repsitory SPECIFYING SINGLE REVISIONS --------------------------- Mercurial accepts several notations for identifying individual revisions. A plain integer is treated as a revision number. Negative integers are treated as offsets from the tip, with -1 denoting the tip. A 40-digit hexadecimal string is treated as a unique revision identifier. A hexadecimal string less than 40 characters long is treated as a unique revision identifier, and referred to as a short-form identifier. A short-form identifier is only valid if it is the prefix of one full-length identifier. Any other string is treated as a tag name, which is a symbolic name associated with a revision identifier. Tag names may not contain the ":" character. The reserved name "tip" is a special tag that always identifies the most recent revision. SPECIFYING MULTIPLE REVISIONS ----------------------------- When Mercurial accepts more than one revision, they may be specified individually, or provided as a continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as an open interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 4:2 gives 4, 3, and 2. ENVIRONMENT VARIABLES --------------------- HGEDITOR:: This is the name of the editor to use when committing. Defaults to the value of EDITOR. (deprecated, use .hgrc) 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. (deprecated, use .hgrc) HGUSER:: This is the string used for the author of a commit. (deprecated, use .hgrc) 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. See hgrc(5) for details of the contents and format of these files.
