if i understand you correctly, you want this:
MYDEV='eth0.1'
[ "$BUTTON" = 'BTN_2' -a "$ACTION" = 'pressed' ] && {
devstatus "$MYDEV" | grep '"up": true' && {
your_action_here
}
}
but this is at least...rude. better you use the correct
JSON-parser like:
. /usr/share/libubox/jshn.sh
json_load "$( devstatus eth0.1 )"
json_get_var 'JSON_VAR_up' 'up'
json_cleanup
in case your dev is up you have e.g.
$JSON_VAR_up = 1
bye, bastian
