This encoder uses standard Bourne shell variable substitution tricks to avoid commonly restricted characters.
Module Ranking and Traits
Module Ranking:
- manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.
Basic Usage

msf encoder(generic_sh) > set TARGET target-id
msf encoder(generic_sh) > show options
... show and set options ...
msf encoder(generic_sh) > exploit
