git-mv

GIT-MV(1)							    Git Manual								 GIT-MV(1)

NAME

       git-mv - Move or rename a file, a directory, or a symlink

SYNOPSIS

       git mv <options>... <args>...

DESCRIPTION

       This script is used to move or rename a file, directory or symlink.

	   git mv [-v] [-f] [-n] [-k] <source> <destination>
	   git mv [-v] [-f] [-n] [-k] <source> ... <destination directory>

       In the first form, it renames <source>, which must exist and be either a file, symlink or directory, to <destination>. In the second form,
       the last argument has to be an existing directory; the given sources will be moved into this directory.

       The index is updated after successful completion, but the change must still be committed.

OPTIONS

       -f, --force
	   Force renaming or moving of a file even if the target exists

       -k
	   Skip move or rename actions which would lead to an error condition. An error happens when a source is neither existing nor controlled
	   by Git, or when it would overwrite an existing file unless -f is given.

       -n, --dry-run
	   Do nothing; only show what would happen

       -v, --verbose
	   Report the names of files as they are moved.
