[root@monitor ~]# LD_DEBUG=help ls

Valid options for the LD_DEBUG environment variable are:

  libs        display library search paths

  reloc       display relocation processing

  files       display progress for input file

  symbols     display symbol table processing

  bindings    display information about symbol binding

  versions    display version dependencies

  all         all previous options combined

  statistics  display relocation statistics

  unused      determined unused DSOs

  help        display this help message and exit

To direct the debugging output into a file instead of standard output

a filename can be specified using the LD_DEBUG_OUTPUT environment variable.
