hg - Mercurial source code management system
hg [-v -d -q -y] <command> [command options] [files]
The hg(1) command provides a command line interface to the Mercurial system.
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.
New files are ignored if they match any of the patterns in .hgignore. As with add, these changes take effect at the next commit.
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)
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.
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
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 -e, --ssh specify ssh command to use --remotecmd specify hg command to run on the remote side
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
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 -p, --parents append source path to dest
aliases: cp
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
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
options: -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns
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 file names 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
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.
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
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
Currently only local repositories are supported.
options: -p, --patch show patch
aliases: in
If no directory is given, the current directory is used.
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 <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
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
The manifest is the list of files being version controlled. If no revision is given then the tip is used.
options: -p, --patch show patch
aliases: out
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.
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
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
This command is not intended to be used by normal users, as it is primarily useful for importing from other SCMs.
This command tries to fix the repository status after an interrupted operation. It should only be necessary when Mercurial suggests it.
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
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 rename files, this information is not yet fully used by merge, nor fully reported by log.
Options: -A, --after record a rename that has already occurred -f, --force forcibly copy over an existing managed file -p, --parents append source path to dest
aliases: mv
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 <rev> revision to revert to -n, --nonrecursive do not recurse into subdirectories
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 <file> name of access log file to write to -E, --errorlog <file> name of error log file to write to -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 -6, --ipv6 use IPv6 in addition to IPv4
The codes used to show the status of files are:
M = changed A = added R = removed ? = not tracked
options:
-m, --modified show only modified files -a, --added show only added files -r, --removed show only removed files -u, --unknown show only unknown (not tracked) files -n, --no-status hide status prefix -0, --print0 end filenames with NUL, for use with xargs -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns
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 <text> message for tag commit log entry -d, --date <datecode> datecode for commit -u, --user <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.
This lists both regular and local tags.
Apply a compressed changegroup file generated by the bundle command.
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.
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
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.
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 repository
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.
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 a closed 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.
(deprecated, use .hgrc)
The default program is "hgmerge", which is a shell script provided by Mercurial with some sensible defaults.
