Quick HEX dump utility in DOS

Recently, I wanted to see the hex dump of a binary file on a server. The server machine did not have my favourite hex GUI editors. I struggled to download a hex dump utility from the web, when my friend showed me how to use the 'debug.exe' tool in DOS to get a hex dump of a file.

On the DOS prompt type :
The 'd' (dump) option would dump the first 128 bytes. Typing 'd' again would give the hex dump of the next block of bytes.

U can type '?' to get a list of all the commands. Type 'q' to quit from debug mode.
