The flags .Fl b , .Fl w and .Fl l specify the size of the data to be modified or examined (byte, word and long, respectively). The .Ar binfile is scanned in search of the symbol .Ar symname (specified with the .Fl s flag) If the symbol is found the current data and address are printed. Next if the .Fl r flag has been given, the current data is replaced with that of .Ar value . .Pp If the second form is used the address .Ar addr specified with the .Fl a flag is used as a direct address into the data section of the binary and no symbol search is performed. .Pp The .Fl o flag specifies an offset in byte, word or long ( .Fl b , .Fl w , or .Fl l ) units from the given locator ( .Fl s or .Fl a ) for .Nm binpatch to perform it's described actions.
