==Tipps==
+
Beispiel Funktionen, für den aktuellen DVB Treiber [[DVB Installation v4l-dvb]].
Programme und libs werden nach dem ausführen der runvdr nicht gefunden?
+
  
Die Lösung ist ziehmlich einfach, die Orginal runvdr (siehe oben) setzt die '''Environment''' auf Null.
+
function DriverLoaded()
 +
{
 +
    grep -qse dvb[-_]core /proc/modules
 +
}
 +
 +
# Load all DVB driver modules needed for your hardware:
 +
function LoadDriver()
 +

 +
    make -C "[[Struktur|$SOURCEDIR]]/DVB/v4l" load
 +
}
 +
 +
# Unload all DVB driver modules loaded in LoadDriver():

Change the effective user id and group id to that of USER.

                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
  -c, --commmand=COMMAND      pass a single COMMAND to the shell with -c
+
  -f, --fast                  pass -f to the shell (for csh or tcsh)
+
  -m, --preserve-environment  do not reset environment variables
+
                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
  -p                          same as -m

                              ^^^^^^^^^^
+
  -s, --shell=SHELL            run SHELL if /etc/shells allows it
+
      --help    display this help and exit
+
      --version  output version information and exit
+
 
+
A mere - implies -l.  If USER not given, assume root.
+
 
+
Report bugs to <bug-coreutils@gnu.org>.
+
</pre>
+
 
+
Man braucht '''su''' lediglich mitzuteilen, die '''Environment''' nicht zu löschen, das wäre in der runvdr, eines folgender Möglichkeiten.
+
 
+
su - $VDRUSR -c "$VDRCMD"
+
su $VDRUSR -m -c "$VDRCMD"
+
su $VDRUSR -p -c "$VDRCMD"
+
 
+
Startest Du das ganze als "root", ist '''sh''' die bessere Wahl.
+
 
+
sh -c "$VDRCMD"
