GIT-VAR(1) Git Manual GIT-VAR(1)
NAME git-var - Show a Git logical variable
SYNOPSIS git var (-l | <variable>)

DESCRIPTION Prints a Git logical variable. Exits with code 1 if the variable has no value.
OPTIONS -l Cause the logical variables to be listed. In addition, all the variables of the Git configuration file .git/config are listed as well. (However, the configuration variables listing functionality is deprecated in favor of git config -l.)
EXAMPLES $ git var GIT_AUTHOR_IDENT Eric W. Biederman <ebiederm@lnxi.com> 1121223278 -0600
VARIABLES GIT_AUTHOR_IDENT The author of a piece of code.
GIT_COMMITTER_IDENT The person who put a piece of code into Git.
GIT_EDITOR Text editor for use by Git commands. The value is meant to be interpreted by the shell when it is used. Examples: ~/bin/vi, $SOME_ENVIRONMENT_VARIABLE, "C:\Program Files\Vim\gvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable, then core.editor configuration, then $VISUAL, then $EDITOR, and then the default chosen at compile time, which is usually vi.
GIT_SEQUENCE_EDITOR Text editor used to edit the todo file while running git rebase -i. Like GIT_EDITOR, the value is meant to be interpreted by the shell when it is used. The order of preference is the $GIT_SEQUENCE_EDITOR environment variable, then sequence.editor configuration, and then the value of git var GIT_EDITOR.
GIT_PAGER Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually less).
GIT_DEFAULT_BRANCH The name of the first branch created in newly initialized repositories.
GIT_SHELL_PATH The path to the global (per-user) gitattributes(5) file.
GIT_CONFIG_SYSTEM The path to the system configuration file, if one is enabled.
GIT_CONFIG_GLOBAL The path to the global (per-user) configuration files, if any.
Most path values contain only one value. However, some can contain multiple values, which are separated by newlines, and are listed in order from highest to lowest priority. Callers should be prepared for any such path value to contain multiple items.
Note that paths are printed even if they do not exist, but not if they are disabled by other environment variables.
