I often multi-thread processes from Terminal by running something like:

sudo etherape &

But I have noticed that I am unable to start multi-threading two processes at the same time by doing something like:

sudo etherape & && sudo wireshark &

And I get this error:

bash: syntax error near unexpected token `&&'

So if this can be done, how can it be done?

  • @MarcosRocha: No I had not tried that, but it worked! So can you please turn that into an answer so that I can accept it.

  • sudo has a -b option. Using & can be a problem with password. However it disowns the process.

  • @richard Note that it is not possible to use shell job control to manipulate background processes started by sudo. Most interactive commands will fail to work properly in background mode.
