Install_name_tool changes the dynamic shared library install names and or adds, changes or deletes the rpaths recorded in a Mach-O binary. For this tool to work when the install names or rpaths are larger the binary should be built with the ld(1) -headerpad_max_install_names option.
-change old new
Changes the dependent shared library install name old to new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contain the old install name in a specified -change option the option is ignored.
-id name
Changes the shared library identification name of a dynamic shared library to name. If the Mach-O binary is not a dynamic shared library and the -id option is specified it is ignored.
-rpath old new
Changes the rpath path name old to new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contain the old rpath path name in a specified -rpath it is an error.
-add_rpath new
Adds the rpath path name new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary already contains the new rpath path name specified in -add_rpath it is an error.
-delete_rpath old
deletes the rpath path name old in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contains the old rpath path name specified in -delete_rpath it is an error.
