msf-nasm_shell-ng

A slightly imroved wrapper around msf-nasm_shell

Wraps msf-nasm_shell with pexpect to extend nasm_shell with:

• newline delimited commands (already had that capability)
• semicolon delimited commands
• shell loop interactive terminal (retained)
• oneshot piped input
• oneshot cli arg input
• Helpful formatting: oneline c-style hexstring followed by opcode comments
