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 POSIX regexp `value_regex` needs to be given. Only the +existing values that match the regexp are updated or unset. If +you want to handle the lines that do *not* match the regex, just +prepend a single exclamation mark in front (see EXAMPLES). + +The type specifier can be either '--int' or '--bool', which will make +'git-config' ensure that the variable(s) are of the given type and +convert the value to the canonical form (simple decimal number for int, +a "true" or "false" string for bool). If no type specifier is passed, +no checks or transformations are performed on the value. + +This command will fail if: + +. The .git/config file is invalid, +. Can not write to .git/config, +. no section was provided, +. the section or key is invalid, +. you try to unset an option which does not exist, +. you try to unset/set an option for which multiple lines match, or +. you use --global option without $HOME being properly set. + + +OPTIONS +------- + +--replace-all:: + Default behavior is to replace at most one line. This replaces + all lines matching the key (and optionally the value_regex). + +--add:: + Adds a new line to the option without altering any existing + values. This is the same as providing '^$' as the value_regex. + +--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 error code 2 if multiple key values were found. + +--get-all:: + Like get, but does not fail if the number of values for the key + is not exactly one. + +--get-regexp:: + Like --get-all, but interprets the name as a regular expression. + +--global:: + Use global ~/.gitconfig file rather than the repository .git/config. + +--system:: + Use system-wide $(prefix)/etc/gitconfig rather than the repository + .git/config. + +--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. + +--bool:: + git-config will ensure that the output is "true" or "false" + +--int:: + git-config will ensure that the output is a simple + decimal number. An optional value suffix of 'k', 'm', or 'g' + in the config file will cause the value to be multiplied + by 1024, 1048576, or 1073741824 prior to output. + + +ENVIRONMENT +----------- + +GIT_CONFIG:: + Take the configuration from the given file instead of .git/config. + Using the "--global" option forces this to ~/.gitconfig. + +GIT_CONFIG_LOCAL:: + Currently the same as $GIT_CONFIG; when Git will support global + configuration files, this will cause it to take the configuration + from the global configuration file in addition to the given file. + + +EXAMPLE +------- + +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/gnu-diff -u" + renames = true + + ; Proxy settings + [core] + gitproxy="ssh" for "ssh://kernel.org/" + gitproxy="proxy-command" for kernel.org + gitproxy="myprotocol-command" for "my://" + gitproxy=default-proxy ; for all the rest + +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.
