* Change the dynamic loader ("ELF interpreter") of executables:
```console
$ patchelf --set-interpreter /lib/my-ld-linux.so.2 my-program
```
* Change the RPATH of executables and libraries:
* Change the `RPATH` of executables and libraries:
```console
$ patchelf --set-rpath /opt/my-libs/lib:/other-libs my-program
```
* Shrink the RPATH of executables and libraries:
* Shrink the `RPATH` of executables and libraries:
```console
$ patchelf --shrink-rpath my-program
```
This removes 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".
This removes 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`.
In addition, the '--allowed-rpath-prefixes' option can be used for
further rpath tuning. For instance, if an executable has an RPATH
"/tmp/build-foo/.libs:/foo/lib", it is probably desirable to keep
the "/foo/lib" reference instead of the "/tmp" entry. To accomplish

* Remove declared dependencies on dynamic libraries (DT_NEEDED
* Remove declared dependencies on dynamic libraries (`DT_NEEDED`
entries):
```console
$ patchelf --remove-needed libfoo.so.1 my-program
```
This option can be given multiple times.
* Add a declared dependency on a dynamic library (DT_NEEDED):
* Add a declared dependency on a dynamic library (`DT_NEEDED`):
```console
$ patchelf --add-needed libfoo.so.1 my-program

This option can be give multiple times.
* Replace a declared dependency on a dynamic library with another one

```console
$ patchelf --replace-needed liboriginal.so.1 libreplacement.so.1 my-program
```
This option can be give multiple times.
* Change SONAME of a dynamic library:
* Change `SONAME` of a dynamic library:
```console
$ patchelf --set-soname libnewname.so.3.4.5 path/to/libmylibrary.so.1.2.3
