I’m sorry, it’s not a secret:
#!/bin/sh
# test for existence and readability of ttyUSB
logger $(whoami)
PORT=`more /etc/gammu-smsdrc |grep tty|cut -d ' ' -f 3|cut -d '/' -f 3`
RESULT=`ls -l /dev/tty*|grep $PORT`
if [ -z "$RESULT" ]
then
echo "error"
else
echo "exists"
fi
exit 0
And now I recognized that using „more“ instead of „cat“ of course is a bad idea
if not running in an interactive terminal. 🙄
Thank you so much for pushing me into the right direction!
