Solved: Toggle Parameter Skript (IVTV toggle audio channel)

as i am not at all experienced in writing bash i post a request here:

The Script should just toggle between 4 statuses.
Each time it is run, it should change the value of # from 0 to 1 to 2 to 3 to 4 to 0
ivtvctl -z #

the actual value of # can be seen by using
ivtvctl -Z (this time it is a capital letter !)

ivtvctl -Z
ioctl VIDIOC_G_TUNER ok
current audio mode : 3
(stereo 1, lang1 3, lang2 2, mono 0)
available subchannels: 0xd
(stereo 0x2, lang1 0x8, lang2 0x4, mono 0x1)

and is represented by the first line's numer (here it is 3)

current audio mode : 3

this would make it easy for all analog dual channel users to switch languages in other applications than vdr.

Old but Useful Link with more Info

Ok, got it

#!/bin/bash
ivtvctl -Z|grep current > /tmp/DualChannelIVTV

if grep -q 1 /tmp/DualChannelIVTV
then
#(lang2): play both channels if the broadcast is in stereo and play the second language if a bilingual broadcast is detected
ivtvctl -z 2
rm /tmp/DualChannelIVTV
elif grep -q 2 /tmp/DualChannelIVTV
then
#(lang1): play both channels if the broadcast is in stereo and play the first language only if a bilingual broadcast is detected (this is the default)
ivtvctl -z 3
rm /tmp/DualChannelIVTV
elif grep -q 3 /tmp/DualChannelIVTV
then
#(mono): play only one channels, whatever the real broadcast mode is
ivtvctl -z 0
rm /tmp/DualChannelIVTV
else
#always play both channels, even if a bilingual broadcast is detected
ivtvctl -z 1
rm /tmp/DualChannelIVTV
