+DESCRIPTION
+-----------
+You can query/set/replace/unset options with this command. The name is
+actually the section and the key separated by a dot, and the value will be
+escaped.
+
+Multiple lines can be added to an option by using the `--add` option.
+If you want to update or unset an option which can occur on multiple
+lines, a `value-pattern` (which is an extended regular expression,
+unless the `--fixed-value` option is given) needs to be given. Only the
+existing values that match the pattern are updated or unset. If
+you want to handle the lines that do *not* match the pattern, just
+prepend a single exclamation mark in front (see also <<EXAMPLES>>),
+but note that this only works when the `--fixed-value` option is not
+in use.
+
+The `--type=<type>` option instructs 'git config' to ensure that incoming and
+outgoing values are canonicalize-able under the given <type>. If no
+`--type=<type>` is given, no canonicalization will be performed. Callers may
+unset an existing `--type` specifier with `--no-type`.
+
+When reading, the values are read from the system, global and
+repository local configuration files by default, and options
+`--system`, `--global`, `--local`, `--worktree` and
+`--file <filename>` can be used to tell the command to read from only
+that location (see <<FILES>>).
+
+When writing, the new value is written to the repository local
+configuration file by default, and options `--system`, `--global`,
+`--worktree`, `--file <filename>` can be used to tell the command to
+write to that location (you can say `--local` but that is the
+default).
+
+This command will fail with non-zero status upon error. Some exit
+codes are:
+
+- The section or key is invalid (ret=1),
+- no section or name was provided (ret=2),
+- the config file is invalid (ret=3),
+- the config file cannot be written (ret=4),
+- you try to unset an option which does not exist (ret=5),
+- you try to unset/set an option for which multiple lines match (ret=5), or
+- you try to use an invalid regexp (ret=6).
+
+On success, the command returns the exit code 0.
+
+A list of all available configuration variables can be obtained using the
+`git help --config` command.
+
+[[OPTIONS]]
+OPTIONS
+-------
+
+--replace-all::
+ Default behavior is to replace at most one line. This replaces
+ all lines matching the key (and optionally the `value-pattern`).
+
+--add::
+ Adds a new line to the option without altering any existing
+ values. This is the same as providing '^$' as the `value-pattern`
+ in `--replace-all`.
+
+--get::
+ Get the value for a given key (optionally filtered by a regex
+ matching the value). Returns error code 1 if the key was not
+ found and the last value if multiple key values were found.
+
+--get-all::
+ Like get, but returns all values for a multi-valued key.
+
+--get-regexp::
+ Like --get-all, but interprets the name as a regular expression and
+ writes out the key names. Regular expression matching is currently
+ case-sensitive and done against a canonicalized version of the key
+ in which section and variable names are lowercased, but subsection
+ names are not.
+
+--get-urlmatch <name> <URL>::
+ When given a two-part name section.key, the value for
+ section.<URL>.key whose <URL> part matches the best to the
+ given URL is returned (if no such key exists, the value for
+ section.key is used as a fallback). When given just the
+ section as name, do so for all the keys in the section and
+ list them. Returns error code 1 if no value is found.
+
+--global::
+ For writing options: write to global `~/.gitconfig` file
+ rather than the repository `.git/config`, write to
+ `$XDG_CONFIG_HOME/git/config` file if this file exists and the
+ `~/.gitconfig` file doesn't.
++
+For reading options: read only from global `~/.gitconfig` and from
+`$XDG_CONFIG_HOME/git/config` rather than from all available files.
++
+See also <<FILES>>.
+
+--system::
+ For writing options: write to system-wide
+ `$(prefix)/etc/gitconfig` rather than the repository
+ `.git/config`.
++
+For reading options: read only from system-wide `$(prefix)/etc/gitconfig`
+rather than from all available files.
++
+See also <<FILES>>.
+
+--local::
+ For writing options: write to the repository `.git/config` file.
+ This is the default behavior.
++
+For reading options: read only from the repository `.git/config` rather than
+from all available files.
++
+See also <<FILES>>.
+
+--worktree::
+ Similar to `--local` except that `$GIT_DIR/config.worktree` is
+ read from or written to if `extensions.worktreeConfig` is
+ enabled. If not it's the same as `--local`. Note that `$GIT_DIR`
+ is equal to `$GIT_COMMON_DIR` for the main working tree, but is of
+ the form `$GIT_DIR/worktrees/<id>/` for other working trees. See
+ linkgit:git-worktree[1] to learn how to enable
+ `extensions.worktreeConfig`.
+
+-f <config-file>::
+--file <config-file>::
+ For writing options: write to the specified file rather than the
+ repository `.git/config`.
++
+For reading options: read only from the specified file rather than from all
+available files.
++
+See also <<FILES>>.
+
+--blob <blob>::
+ Similar to `--file` but use the given blob instead of a file. E.g.
+ you can use 'master:.gitmodules' to read values from the file
+ '.gitmodules' in the master branch. See "SPECIFYING REVISIONS"
+ section in linkgit:gitrevisions[7] for a more complete list of
+ ways to spell blob names.
+
+--remove-section::
+ Remove the given section from the configuration file.
+
+--rename-section::
+ Rename the given section to a new name.
+
+--unset::
+ Remove the line matching the key from config file.
+
+--unset-all::
+ Remove all lines matching the key from config file.
+
+-l::
+--list::
+ List all variables set in config file, along with their values.
+
+--fixed-value::
+ When used with the `value-pattern` argument, treat `value-pattern` as
+ an exact string instead of a regular expression. This will restrict
+ the name/value pairs that are matched to only those where the value
+ is exactly equal to the `value-pattern`.
+
+--type <type>::
+ 'git config' will ensure that any input or output is valid under the given
+ type constraint(s), and will canonicalize outgoing values in `<type>`'s
+ canonical form.
++
+Valid `<type>`'s include:
++
+- 'bool': canonicalize values as either "true" or "false".
+- 'int': canonicalize values as simple decimal numbers. An optional suffix of
+ 'k', 'm', or 'g' will cause the value to be multiplied by 1024, 1048576, or
+ 1073741824 upon input.
+- 'bool-or-int': canonicalize according to either 'bool' or 'int', as described
+ above.
+- 'path': canonicalize by adding a leading `~` to the value of `$HOME` and
+ `~user` to the home directory for the specified user. This specifier has no
+ effect when setting the value (but you can use `git config section.variable
+ ~/` from the command line to let your shell do the expansion.)
+- 'expiry-date': canonicalize by converting from a fixed or relative date-string
+ to a timestamp. This specifier has no effect when setting the value.
+- 'color': When getting a value, canonicalize by converting to an ANSI color
+ escape sequence. When setting a value, a sanity-check is performed to ensure
+ that the given value is canonicalize-able as an ANSI color, but it is written
+ as-is.
++
+
+--bool::
+--int::
+--bool-or-int::
+--path::
+--expiry-date::
+ Historical options for selecting a type specifier. Prefer instead `--type`
+ (see above).
+
+--no-type::
+ Un-sets the previously set type specifier (if one was previously set). This
+ option requests that 'git config' not canonicalize the retrieved variable.
+ `--no-type` has no effect without `--type=<type>` or `--<type>`.
+
+-z::
+--null::
+ For all options that output values and/or keys, always
+ end values with the null character (instead of a
+ newline). Use newline instead as a delimiter between
+ key and value. This allows for secure parsing of the
+ output without getting confused e.g. by values that
+ contain line breaks.
+
+--name-only::
+ Output only the names of config variables for `--list` or
+ `--get-regexp`.
+
+--show-origin::
+ Augment the output of all queried config options with the
+ origin type (file, standard input, blob, command line) and
+ the actual origin (config file path, ref, or blob id if
+ applicable).
+
+--show-scope::
+ Similar to `--show-origin` in that it augments the output of
+ all queried config options with the scope of that value
+ (worktree, local, global, system, command).
+
+--get-colorbool <name> [<stdout-is-tty>]::
+
+ Find the color setting for `<name>` (e.g. `color.diff`) and output
+ "true" or "false". `<stdout-is-tty>` should be either "true" or
+ "false", and is taken into account when configuration says
+ "auto". If `<stdout-is-tty>` is missing, then checks the standard
+ output of the command itself, and exits with status 0 if color
+ is to be used, or exits with status 1 otherwise.
+ When the color setting for `name` is undefined, the command uses
+ `color.ui` as fallback.
+
+--get-color <name> [<default>]::
+
+ Find the color configured for `name` (e.g. `color.diff.new`) and
+ output it as the ANSI color escape sequence to the standard
+ output. The optional `default` parameter is used instead, if
+ there is no color configured for `name`.
++
+`--type=color [--default=<default>]` is preferred over `--get-color`
+(but note that `--get-color` will omit the trailing newline printed by
+`--type=color`).
+
+-e::
+--edit::
+ Opens an editor to modify the specified config file; either
+ `--system`, `--global`, or repository (default).
+
+--[no-]includes::
+ Respect `include.*` directives in config files when looking up
+ values. Defaults to `off` when a specific file is given (e.g.,
+ using `--file`, `--global`, etc) and `on` when searching all
+ config files.
+
+--default <value>::
+ When using `--get`, and the requested variable is not found, behave as if
+ <value> were the value assigned to the that variable.
+
+CONFIGURATION
+-------------
+`pager.config` is only respected when listing configuration, i.e., when
+using `--list` or any of the `--get-*` which may return multiple results.
+The default is to use a pager.
+
+[[FILES]]
+FILES
+-----
+
+By default, 'git config' will read configuration options from multiple
+files:
+
+$(prefix)/etc/gitconfig::
+ System-wide configuration file.
+
+$XDG_CONFIG_HOME/git/config::
+~/.gitconfig::
+ User-specific configuration files. When the XDG_CONFIG_HOME environment
+ variable is not set or empty, $HOME/.config/ is used as
+ $XDG_CONFIG_HOME.
++
+These are also called "global" configuration files. If both files exist, both
+files are read in the order given above.
+
+$GIT_DIR/config::
+ Repository specific configuration file.
+
+$GIT_DIR/config.worktree::
+ This is optional and is only searched when
+ `extensions.worktreeConfig` is present in $GIT_DIR/config.
+
+You may also provide additional configuration parameters when running any
+git command by using the `-c` option. See linkgit:git[1] for details.
+
+Options will be read from all of these files that are available. If the
+global or the system-wide configuration files are missing or unreadable they
+will be ignored. If the repository configuration file is missing or unreadable,
+'git config' will exit with a non-zero error code. An error message is produced
+if the file is unreadable, but not if it is missing.
+
+The files are read in the order given above, with last value found taking
+precedence over values read earlier. When multiple values are taken then all
+values of a key from all files will be used.
+
+By default, options are only written to the repository specific
+configuration file. Note that this also affects options like `--replace-all`
+and `--unset`. *'git config' will only ever change one file at a time*.
+
+You can limit which configuration sources are read from or written to by
+specifying the path of a file with the `--file` option, or by specifying a
+configuration scope with `--system`, `--global`, `--local`, or `--worktree`.
+For more, see <<OPTIONS>> above.
+
+[[SCOPES]]
+SCOPES
+------
+
+Each configuration source falls within a configuration scope. The scopes
+are:
+
+system::
+ $(prefix)/etc/gitconfig
+
+global::
+ $XDG_CONFIG_HOME/git/config
++
+~/.gitconfig
+
+local::
+ $GIT_DIR/config
+
+worktree::
+ $GIT_DIR/config.worktree
+
+command::
+ GIT_CONFIG_{COUNT,KEY,VALUE} environment variables (see <<ENVIRONMENT>>
+ below)
++
+the `-c` option
+
+With the exception of 'command', each scope corresponds to a command line
+option: `--system`, `--global`, `--local`, `--worktree`.
+
+When reading options, specifying a scope will only read options from the
+files within that scope. When writing options, specifying a scope will write
+to the files within that scope (instead of the repository specific
+configuration file). See <<OPTIONS>> above for a complete description.
+
+Most configuration options are respected regardless of the scope it is
+defined in, but some options are only respected in certain scopes. See the
+respective option's documentation for the full details.
+
+Protected configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Protected configuration refers to the 'system', 'global', and 'command' scopes.
+For security reasons, certain options are only respected when they are
+specified in protected configuration, and ignored otherwise.
+
+Git treats these scopes as if they are controlled by the user or a trusted
+administrator. This is because an attacker who controls these scopes can do
+substantial harm without using Git, so it is assumed that the user's environment
+protects these scopes against attackers.
+
+[[ENVIRONMENT]]
+ENVIRONMENT
+-----------
+
+GIT_CONFIG_GLOBAL::
+GIT_CONFIG_SYSTEM::
+ Take the configuration from the given files instead from global or
+ system-level configuration. See linkgit:git[1] for details.
+
+GIT_CONFIG_NOSYSTEM::
+ Whether to skip reading settings from the system-wide
+ $(prefix)/etc/gitconfig file. See linkgit:git[1] for details.
+
+See also <<FILES>>.
+
+GIT_CONFIG_COUNT::
+GIT_CONFIG_KEY_<n>::
+GIT_CONFIG_VALUE_<n>::
+ If GIT_CONFIG_COUNT is set to a positive number, all environment pairs
+ GIT_CONFIG_KEY_<n> and GIT_CONFIG_VALUE_<n> up to that number will be
+ added to the process's runtime configuration. The config pairs are
+ zero-indexed. Any missing key or value is treated as an error. An empty
+ GIT_CONFIG_COUNT is treated the same as GIT_CONFIG_COUNT=0, namely no
+ pairs are processed. These environment variables will override values
+ in configuration files, but will be overridden by any explicit options
+ passed via `git -c`.
++
+This is useful for cases where you want to spawn multiple git commands
+with a common configuration but cannot depend on a configuration file,
+for example when writing scripts.
+
+GIT_CONFIG::
+ If no `--file` option is provided to `git config`, use the file
+ given by `GIT_CONFIG` as if it were provided via `--file`. This
+ variable has no effect on other Git commands, and is mostly for
+ historical compatibility; there is generally no reason to use it
+ instead of the `--file` option.
+
+[[EXAMPLES]]
+EXAMPLES
+--------
+
+Given a .git/config like this:
+
+------------
+#
+# This is the config file, and
+# a '#' or ';' character indicates
+# a comment
+#
+
+; core variables
+[core]
+ ; Don't trust file modes
+ filemode = false
+
+; Our diff algorithm
+[diff]
+ external = /usr/local/bin/diff-wrapper
+ renames = true
+
+; Proxy settings
+[core]
+ gitproxy=proxy-command for kernel.org
+ gitproxy=default-proxy ; for all the rest
+
+; HTTP
+[http]
+ sslVerify
+[http "https://weak.example.com"]
+ sslVerify = false
+ cookieFile = /tmp/cookie.txt
+------------
+
+you can set the filemode to true with
+
+------------
+% git config core.filemode true
+------------
+
+The hypothetical proxy command entries actually have a postfix to discern
+what URL they apply to. Here is how to change the entry for kernel.org
+to "ssh".
+
+------------
+% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
+------------
+
+This makes sure that only the key/value pair for kernel.org is replaced.
+
+To delete the entry for renames, do
+
+------------
+% git config --unset diff.renames
+------------
+
+If you want to delete an entry for a multivar (like core.gitproxy above),
+you have to provide a regex matching the value of exactly one line.
+
+To query the value for a given key, do
+
+------------
+% git config --get core.filemode
+------------
+
+or
+
+------------
+% git config core.filemode
+------------
+
+or, to query a multivar:
+
+------------
+% git config --get core.gitproxy "for kernel.org$"
+------------
+
+If you want to know all the values for a multivar, do:
+
+------------
+% git config --get-all core.gitproxy
+------------
+
+If you like to live dangerously, you can replace *all* core.gitproxy by a
+new one with
+
+------------
+% git config --replace-all core.gitproxy ssh
+------------
+
+However, if you really only want to replace the line for the default proxy,
+i.e. the one without a "for ..." postfix, do something like this:
+
+------------
+% git config core.gitproxy ssh '! for '
+------------
+
+To actually match only values with an exclamation mark, you have to
+
+------------
+% git config section.key value '[!]'
+------------
+
+To add a new proxy, without altering any of the existing ones, use
+
+------------
+% git config --add core.gitproxy '"proxy-command" for example.com'
+------------
+
+An example to use customized color from the configuration in your
+script:
+
+------------
+#!/bin/sh
+WS=$(git config --get-color color.diff.whitespace "blue reverse")
+RESET=$(git config --get-color "" "reset")
+echo "${WS}your whitespace color or blue reverse${RESET}"
+------------
+
+For URLs in `https://weak.example.com`, `http.sslVerify` is set to
+false, while it is set to `true` for all others:
+
+------------
+% git config --type=bool --get-urlmatch http.sslverify https://good.example.com
+true
+% git config --type=bool --get-urlmatch http.sslverify https://weak.example.com
+false
+% git config --get-urlmatch http https://weak.example.com
+http.cookieFile /tmp/cookie.txt
+http.sslverify false
+------------

+
+BUGS
+----
+When using the deprecated `[section.subsection]` syntax, changing a value
+will result in adding a multi-line key instead of a change, if the subsection
+is given with at least one uppercase character. For example when the config
+looks like
+
+--------
+ [section.subsection]
+ key = value1
+--------
+
+and running `git config section.Subsection.key value2` will result in
+
+--------
+ [section.subsection]
+ key = value1
+ key = value2
