==name sudo

==short-description

Launch an executable with modified capabilities and / or other properties.

==long-description

The command operates in one of two modes, depending on whether C<--disk> is specified. With this option, a copy of the exe is made on the C drive, modified there then executed. Without it, the process is launched then before it is resumed the properties are modified in the kernel. The default (without C<--disk>) is neater but is limited in that it cannot change heap or stack sizes, and if the DLLs that are linked to have too many capabilities to allow the exe to launch as is, you won't get far enough to change them. Previously the C<--disk> option was the default. If no capability or sid etc options are specified then the exe will be launched with capabilities C<All -TCB> and no other changes.

==argument string exe-name

The executable to modify then launch.

==argument string arguments optional last

Arguments to pass to the exe.

==option string a add-cap multiple

Adds the specified capability.

==option string r remove-cap multiple

Removes the specified capability (if a cap is included in both add and remove lists, the remove takes precedence).

==option uint s sid

Sets the Secure ID to the specified value.

==option uint v vid

Sets the Vendor ID to the specified value.

==option uint m heap-min

Sets the process's default minimum heap size to the specified value (in bytes).

==option uint x heap-max

Sets the process's default maximum heap size to the specified value (in bytes).

==option uint z stack-size

Sets the process's default stack size to the specified value (in bytes).

==option int p process-priority

Sets the process priority to the specified value (as per C<TProcessPriority>).

==option bool k keep

Do not delete the modified exe when the process exits. If the exe is in the Core ROM, this option will keep the modified binary in memory until next reboot, such that any other code that launches the exe will pick up these settings (running sudo a second time on this exe without C<--keep> will undo it).

==option bool d disk

Change the on-disk binary rather than modifying the in-memory kernel process attributes. This option is required for changing heap and stack sizes. On WINSCW the C<--disk> option still operates on E32 binaries, therefore it is not possible to modify a WINSCW binary with C<--disk>.

==option bool w wait

Wait for a keypress before resuming the process. Use this option if you need to examine the process before it runs.
