The gdb page was created to encourage normal users to send us
backtraces. It is not meant as a complete manual for gdb. That is
available either via googling: gdb manual

(That search will bring this up as the first hit
http://sourceware.org/gdb/documentation/ )

Single step debugging is easy in gdb. Once you are in gdb, you just 
either "step", "next" or "continue". Each of these commands can be 
abbreviated to a single character. So s<enter> will step once. Pressing 
enter without any command will repeat the previous one.
