.SH NAME
ldconfig \- configure dynamic linker run time bindings
.SH SYNOPSIS
.B ldconfig
.RB [OPTIONS...]
.SH DESCRIPTION
.B ldconfig
creates the necessary links and cache (for use by the run-time linker)
to the most recent shared libraries found in the directories specified
on the command line, in the file
.IR /etc/ld.so.conf ,
and in the trusted directories
.RI ( /usr/lib
and
.IR /lib ).
.B ldconfig
checks the header and file names of the libraries it encounters when
determining which versions should have their links updated.
.B ldconfig
ignores symbolic links when scanning for libraries.
.B ldconfig
should normally be run by the super-user as it may require write
permission on some root owned directories and files.
It is normally run automatically at bootup, or manually
whenever new shared libraries are installed.
