Either type the "source /path/to/.gdbinit" command at the GDB prompt,
or start GDB from the directory of that file, so that it is loaded
automatically.

It defines several defaults and commands useful for debugging GDB.
It's a text file, so you can read it and see what it does.

Remember that .gdbinit is gone, in favor of gdb-gdb.gdb [there's a
reason it's spelled that way :-)]
And there should be no need to manually load it, that should happen
automatically (except when debugging a newer gdb with an older gdb).

For reference sake,
- gdb-gdb.gdb is installed in the build tree from gdb-gdb.gdb.in in
the source tree
- there is also gdb-gdb.py, which provides additional Python based
support for debugging gdb with gdb.

gdb-gdb.gdb
 ^   ^   ^
 ^   ^   ^---- It's a gdb script.
 ^   ^         If it were Python this would be .py.
 ^   ^
 ^   ^-------- "-gdb" is a gdb convention, it's the suffix added to a file
 ^             for auxiliary support.
 ^             E.g., gdb will auto-load libstdc++.so-gdb.py (version elided)
 ^             which contains the std c++ pretty-printers.
 ^
 ^------------ This init script is for the program named "gdb".
               If this were for readelf the script would be named
               readelf-gdb.gdb.

Kind of a funny name, but there is a convention behind it. :-)
