.. program:: llvm-install-name-tool
:program:`llvm-install-name-tool` [options] input
:program:`llvm-install-name-tool` is a tool to manipulate dynamic shared library install names and rpaths listed in a Mach-O binary.
For most scenarios, it works as a drop-in replacement for Apple's :program:`install_name_tool`.
At least one of the following options are required, and some options can be combined with other options. Options :option:`-add_rpath`, :option:`-delete_rpath`, and :option:`-rpath` can be combined in an invocation only if they do not share the same <rpath> value.
.. option:: -add_rpath <rpath> Add an rpath named ``<rpath>`` to the specified binary. Can be specified multiple times to add multiple rpaths. Throws an error if ``<rpath>`` is already listed in the binary.
.. option:: -change <old_install_name> <new_install_name> Change an install name ``<old_install_name>`` to ``<new_install_name>`` in the specified binary. Can be specified multiple times to change multiple dependent shared library install names. Option is ignored if ``<old_install_name>`` is not listed in the specified binary.
.. option:: -delete_rpath <rpath> Delete an rpath named ``<rpath>`` from the specified binary. Can be specified multiple times to delete multiple rpaths. Throws an error if ``<rpath>`` is not listed in the binary.
.. option:: -delete_all_rpaths Deletes all rpaths from the binary.
.. option:: --help, -h Print a summary of command line options.
.. option:: -id <name> Change shared library's identification name under LC_ID_DYLIB to ``<name>`` in the specified binary. If specified multiple times, only the last :option:`-id` option is selected. Option is ignored if the specified Mach-O binary is not a dynamic shared library.
.. option:: -rpath <old_rpath> <new_rpath> Change an rpath named ``<old_rpath>`` to ``<new_rpath>`` in the specified binary. Can be specified multiple times to change multiple rpaths. Throws an error if ``<old_rpath>`` is not listed in the binary or ``<new_rpath>`` is already listed in the binary.
.. option:: --version, -V Display the version of the :program:`llvm-install-name-tool` executable.
:program:`llvm-install-name-tool` exits with a non-zero exit code if there is an error. Otherwise, it exits with code 0.
