., the value for

.. whose part matches the best to the given URL is returned (if no such key exists, the value for

. is used as a fallback). When given just the

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 <>. --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 <>. --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 <>. --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//` for other working trees. See linkgit:git-worktree[1] to learn how to enable `extensions.worktreeConfig`. -f :: --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 <>. --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 :: 'git config' will ensure that any input or output is valid under the given type constraint(s), and will canonicalize outgoing values in ``'s canonical form. + Valid ``'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 expanding 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=` or `--`. -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 []:: Find the color setting for `` (e.g. `color.diff`) and output "true" or "false". `` should be either "true" or "false", and is taken into account when configuration says "auto". If `` 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 []:: 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=]` 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`, `--local` (default), `--worktree`, or `--file `. --[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 :: When using `--get`, and the requested variable is not found, behave as if were the value assigned to 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 <> 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 <> 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 <> 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 $(prefix)/etc/gitconfig file. See linkgit:git[1] for details. See also <>. GIT_CONFIG_COUNT:: GIT_CONFIG_KEY_:: GIT_CONFIG_VALUE_:: If GIT_CONFIG_COUNT is set to a positive number, all environment pairs GIT_CONFIG_KEY_ and GIT_CONFIG_VALUE_ up to that number will be added to the process's runtime configuration. The config pairs are zero-indexed. Any missing key or value is treated as an error. An empty GIT_CONFIG_COUNT is treated the same as GIT_CONFIG_COUNT=0, namely no pairs are processed. These environment variables will override values in configuration files, but will be overridden by any explicit options passed via `git -c`. + This is useful for cases where you want to spawn multiple git commands with a common configuration but cannot depend on a configuration file, for example when writing scripts. GIT_CONFIG:: If no `--file` option is provided to `git config`, use the file given by `GIT_CONFIG` as if it were provided via `--file`. This variable has no effect on other Git commands, and is mostly for historical compatibility; there is generally no reason to use it instead of the `--file` option. [[EXAMPLES]] EXAMPLES -------- Given a .git/config like this: ------------ # # This is the config file, and # a '#' or ';' character indicates # a comment # ; core variables [core] ; Don't trust file modes filemode = false ; Our diff algorithm [diff] external = /usr/local/bin/diff-wrapper renames = true ; Proxy settings [core] gitproxy=proxy-command for kernel.org gitproxy=default-proxy ; for all the rest ; HTTP [http] sslVerify [http "https://weak.example.com"] sslVerify = false cookieFile = /tmp/cookie.txt ------------ you can set the filemode to true with ------------ % git config core.filemode true ------------ The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh". ------------ % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$' ------------ 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 ------------ include::config.txt[] 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 -------- GIT --- Part of the linkgit:git[1] suite
