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.
|
|
|
|
|
|
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 static-http:// protocol which is much slower but does not
|
|
|
require a special server on the web host.

FILE NAME PATTERNS
|
|
|
------------------
|
|
|
|
|
|
Mercurial accepts several notations for identifying one or more
|
|
|
files at a time.
|
|
|
|
|
|
By default, Mercurial treats filenames 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
|
|
|
|
|
|
|
|
|
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 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.
|
|

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)
|
|
|
|
|
|
HGRCPATH::
|
|
|
A list of files or directories to search for hgrc files. Item
|
|
|
separator is ":" on Unix, ";" on Windows. If HGRCPATH is not set,
|
|
|
platform default search path is used. If empty, only .hg/hgrc of
|
|
|
current repository is read.
|
|
|
|
|
|
For each element in path, if a directory, all entries in directory
|
|
|
ending with ".rc" are added to path. Else, element itself is
|
|
|
added to path.
|
|
|
|
|
|
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. For details, see hgignore(5).
|
|
|
|
|
|
.hgtags::
|
|
|
This file contains changeset hash values and text tag names (one of each
|
|
|
separated by spaces) that correspond to tagged versions of the repository
|
|
|
contents.
|
|
|
|
|
|
/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc::
|
|
|
This file contains defaults and configuration. Values in .hg/hgrc
|
|
|
override those in $HOME/.hgrc, and these override settings made in the
|
|
|
global /etc/mercurial/hgrc configuration. See hgrc(5) for details of
|
|
|
the contents and format of these files.
|
|
|
|
|
|
Some commands (e.g. revert) produce backup files ending in .orig, if
|
|
|
the .orig file already exists and is not tracked by Mercurial, it
|
|
|
will be overwritten.
