command chaining with "&&" doesn't work AS IT strips one level of quoting

[Origaman]

Binary package hint: kdesudo

On Feisty, with kdesu I was able to use it to execute two or more commands in a row without repeatedly being asked for a password by chaining them like this: kdesu "command1 && command2 && ...".
With kdesudo, this isn't working any more. Only the first command is executed with root privileges, all further commands with normal user privileges.

That this ever worked in kdesu was a bug IMHO. kdesudo (kdesu is now a link to it)

Here's why

   sudo "id && whoami" -> sudo: id && whoami: command not found

Even su complain. To do what you want with su one has to use

  su -c "comamnd1 && command2"

There is a -c (pass to shell) command. As su always asked for a password, implementing - c was
is necessary. Sudo does not ask the second time, so sudo command1 && sudo command is the
natural thing.

Task of kdesu and kdesudo is run a/one command as root. Not to emulate part of the shell (aka
implement &&).

As sudo does not have -c and su used it for &&, || etc task. I would suggest that this is the right
fix. Don't reimplement kdesu's non unixish behaviour.

Bug 157733 is the side of the same coin. Marking as duplicate.
Bug is that kdesu/do strips one level of quoting. Breaking with
usual shell parsing behaviour:

kdesudo strips one level of quotes, that makes it unnecessarily complicated
and deviates from sudo behaviour (and FWIW all other command line tools).

  kdesudo kate "one two" # opens 2 files: 'one' and 'two' -> BUG

  sudo kate "one two" # opens the file "one two" as all other commands do
