Hello

 

So I was trying to adapt a plugin and it has this line in its rc start srcipt:

	CMDLINE="sudo -u $RUNAS tvheadend -c $DATADIR -u $RUNAS -g $GROUP -f 2>&1 >/dev/null"

$CMDLINE

• 
  I have the following questions:
  

1. 
   
2. If the 2>&1 >/dev/null stuff is meaning to silence all output, stdout and stderr, doesn't it have to be  >/dev/null 2>&1 ??
   
3. If I try either of those commands, the syslog says: see next post for #2

Sep  2 01:42:21 Server sudo:     root : TTY=pts/0 ; PWD=/etc/rc.d ; USER=root ; COMMAND=/usr/bin/tvheadend -c /mnt/cache/.apps/tvheadend -u root -g video -f > /dev/null 2>$stuff$1

and the command does not work properly. How can I avoid the $stuff$ ??

 

Thanks

 

I came to the idea that the $stuff$ thing had something to do with the syslog formatting in unmenu - And I was right.

 

Anyway, there must be another reason why this does not work. The complete function looks like this.

 

tvheadend_start()
{
        # no-op if not enabled
        if [ $SERVICE != "enable" ]; then
                return
        fi

        # no-op if already running
        if [ -r /var/run/tvheadend.pid ]; then
                return
        fi

        # if directory doesn't exist or Tvheadend is not found, install it
        if [ ! -e "/usr/bin/tvheadend" ]; then
                tvheadend_install
        fi
        CMDLINE="sudo -u $RUNAS tvheadend -c $DATADIR -u $RUNAS -g $GROUP -f 2>&1 > /dev/null"
        echo "Starting Tvheadend: $CMDLINE"
        sleep 1
        $CMDLINE

        while [ ! -e /var/run/tvheadend.pid ]; do
                sleep 1
        done
        echo "... OK"
        sleep 1
}

Now when i invoke it via /etc/rc.d/rc.tvheadend start, i get an error and an description on how tvheadend is used

 

Starting Tvheadend: sudo -u root tvheadend -c /mnt/cache/.apps/tvheadend -u root -g video -f 2>&1 > /dev/null
Usage: tvheadend [OPTIONS]

Generic Options

  -h, --help                  Show this page
...........

And the script is stuck (because tvheadend.pid isn't created)

Now, when I abort the script and take that very codeline it echoed before "crashing" and paste it back in, it works...

Any idea about that? How can I "debug" something like this?

Does anyone have an idea on this?
