NAME
       patchelf - Modify ELF files

SYNOPSIS
       patchelf OPTION FILE

DESCRIPTION
       PatchELF is a simple utility for modifying existing ELF executables and
       libraries.  It can change the dynamic loader ("ELF interpreter") of
       executables and change the RPATH of executables and libraries.

OPTIONS
       The single option given operates on a given FILE, editing in place.

       --set-interpreter INTERPRETER
              Change the dynamic loader ("ELF interpreter") of executable
              given to INTERPRETER.

       --print-intepreter
              Prints the ELF interpreter of the executable.

       --set-rpath RPATH
              Change the RPATH of the executable or library to RPATH.

       --shrink-rpath
              Remove from the RPATH all directories that do not contain a
              library referenced by DT_NEEDED fields of the executable or
              library.

              For instance, if an executable references one library libfoo.so,
              has an RPATH "/lib:/usr/lib:/foo/lib", and libfoo.so can only be
              found in /foo/lib, then the new RPATH will be "/foo/lib".

       --print-rpath
              Prints the RPATH for an executable or library.

       --force-rpath
              Forces the use of the obsolete DT_RPATH in the file instead of
              DT_RUNPATH. By default DT_RPATH is converted to DT_RUNPATH.

       --debug
              Prints details of the changes made to the input file.

       --version
              Shows the version of patchelf.
