SYNOPSIS
git rev-parse [options] args...
DESCRIPTION
git rev-parse translates ref names, symbolic references, and other arguments into SHA-1 hashes. It also provides information about the repository structure, such as the root directory, git directory, and current branch.This plumbing command is widely used in scripts for resolving refs and querying repository metadata.
PARAMETERS
--short [length]
Abbreviated hash.--abbrev-ref
Show short ref name.--verify
Verify object exists.--show-toplevel
Show repository root.--git-dir
Show .git directory.--is-inside-work-tree
Check if in work tree.--show-prefix
Show path of current directory relative to repository root.--show-cdup
Show path from current directory to repository root.--is-bare-repository
Print "true" if the repository is bare, "false" otherwise.--absolute-git-dir
Like --git-dir, but output is always an absolute path.--symbolic
Show symbolic name instead of SHA-1.--symbolic-full-name
Like --symbolic but show full ref name (e.g., refs/heads/master).--quiet
Only meaningful with --verify. Do not output error message on failure, just exit with non-zero status.
