Dear all, I would like to modify some DOS commands. For example, I want to change REN (rename) to WANG. How can I do it? Can I do it using commands? Or which system file should I modify to achieve this goal? I hope the experts can explain it to me. Thanks

All internal commands are in the command.com file. To modify it, you need to disassemble this file, which is quite difficult.

LS is correct, all DOS internal commands are in COMMAND.COM. However, the commands are not encrypted and can be directly found. For example, the hexadecimal code corresponding to dir is 64 69 72, and the hexadecimal code for cd is 63 64
