COMMANDS
--------
list::
List all variables set in config file, along with their values.
get::
Emits the value of the specified key. If key is present multiple times
in the configuration, emits the last value. If `--all` is specified,
emits all values associated with key. Returns error code 1 if key is
not present.
set::
Set value for one or more config options. By default, this command
refuses to write multi-valued config options. Passing `--all` will
replace all multi-valued config options with the new value, whereas
`--value=` will replace all config options whose values match the given
pattern.
unset::
Unset value for one or more config options. By default, this command
refuses to unset multi-valued keys. Passing `--all` will unset all
multi-valued config options, whereas `--value` will unset all config
options whose values match the given pattern.
rename-section::
Rename the given section to a new name.
remove-section::
Remove the given section from the configuration file.
edit::
Opens an editor to modify the specified config file; either
`--system`, `--global`, `--local` (default), `--worktree`, or
`--file <config-file>`.

permitted).
--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.
--all::
With `get`, return all values for a multi-valued key.
--get-all::
Like get, but returns all values for a multi-valued key.
---regexp::
With `get`, interpret the name as a regular expression. 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-regexp::
Like --get-all, but interprets the name as a regular expression and
writes out the key names. Regular expression matching is currently

in which section and variable names are lowercased, but subsection
names are not.
