git-var

Print the value of a Git logical variable

$ git var [GIT_AUTHOR_IDENT|GIT_COMMITTER_IDENT|GIT_EDITOR|GIT_PAGER]

$ git var -l

git var [-e | --export]

-e, --export
    Export the variable to the environment (only when the variable is a valid shell identifier).


    The name of the Git variable to display. Examples include GIT_DIR, GIT_WORK_TREE, GIT_VERSION, GIT_CONFIG_NOSYSTEM, and custom configuration variables like `my.setting`.

The git-var command provides a mechanism to query and display various Git repository-related variables and configuration settings. It can be used to retrieve information like the Git directory ('.git'), the work tree, Git version, and various configuration values stored in the Git configuration files.

The primary function is to echo the value of variables relevant to the repository context. It is often used in shell scripts and other automation tasks to dynamically configure Git behavior based on the environment or project settings. This command simplifies access to Git's internal settings, making it easier to integrate Git with other tools and scripts.

It helps retrieve settings without having to parse raw configuration files. It's important to note that the output of git-var is intended to be stable, so scripts relying on it should not break due to minor Git version updates, assuming the variable names remain consistent.

Not all environment variables defined when executing `git` are accessible through `git var`. This command is primarily intended for Git's internal variables and configuration settings. Some variables available through regular Git commands are not directly accessible.

• To get the Git directory: git var GIT_DIR
• To get the Git work tree: git var GIT_WORK_TREE
• To export a configuration value: git var --export my.custom.variable
