start-stop-daemon and Valgrind

Question

I use start-stop-daemon to start up programs and would like to use it together with Valgrind. This is how I use start-stop-daemon: ``` start-stop-daemon --start --background --exec ${BINPATH}/myPgm -- myPgm ``` This is how I use Valgrind on a standalone application (junk): ``` valgrind --tool=memcheck --leak-check=yes ./junk ``` and that works. I would want to do something like: ``` start-stop-daemon --start --background --exec valgrind --tool=memcheck --leak-check=yes --log-file=/usr/magnus/logFile ${BINPATH}/myPgm -- myPgm ``` It seems start-stop-daemon accepts valgrind (if I only have valgrind without it's flags `--tool=memcheck --leak-check=yes --log-file=/usr/magnus/logFile` it seem to be accepted) but start-stop-daemon won't accept it. I get start-stop-daemon: `unrecognized option '--tool=memcheck'` for the valgrind flags. Does anybody know how this can be done?

Accepted Answer

The "--" in there is used to separate start-stop-daemon's arguments from the ones passed to your executable. So, the myPgm you have after "--" is actually supplied as an argument to your myPgm executable. I think it's extraneous in your first example.

You need to use "--" to split valgrind's args out, like this:

```
start-stop-daemon --start --background --exec valgrind -- --tool=memcheck --leak-check=yes --log-file=/usr/magnus/logFile ${BINPATH}/myPgm
```
