There's no such command.  The general method is to use
an assignment expression.  You use a cast to determine
the size of memory (byte, word...) you want to write.

(gdb) set *(char *) 0xabcd = -1

You can do tricky things by using or omitting "signed",
and usually write up to an 8-byte word by using "long long".
