NAME
install_name_tool - change dynamic shared library install names
SYNOPSIS
install_name_tool [-change old new ] ... [-rpath old new ] ... [-add_rpath new ] ... [-delete_rpath new ] ... [-id
name] file
DESCRIPTION
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 speci-
fied -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 speci-
fied. 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.
