I want to start a program in a screen as the user "XYZ" with a script. This is my script in short form:
# replace <newuser> with the user you wish to run teamspeak 3 with.
USER="teamspeak"
# Do not change this path
PATH=/bin:/usr/bin:/sbin:/usr/sbin
# The path to the teamspeak 3 server/scripts . example = /home/teamspeak3/teamspeak3-server
DIR=/home/teamspeak/voiceserver/teamspeak3
DAEMON=$DIR/ts3server_startscript.sh
# Change all PARAMS to your needs. I required the ini so teamspeak used MySQL
PARAMS="inifile=ts3server.ini"
#Name = The screen will be named from this.
NAME=teamspeak3
DESC="Teamspeak Server 3"
case "$1" in
start)
echo "Starting $DESC"
script -q -c "su $USER -l -c \"screen -m -d -S $NAME $DAEMON start\"" /dev/null
;;
stop)
su $USER -l -c "screen -S $NAME -X quit "
echo " ... done. $DESC Stopped."
;;
restart)
su $USER -l -c "screen -S $NAME -X quit "
echo " Closed Process, Restarting"
script -q -c "su $USER -l -c \"screen -m -d -S $NAME $DAEMON start\"" /dev/null
echo " ... done. $DESC Restarted"
;;
status)
# Check whether there's a "Team Speak 3" process
ps aux | grep -v grep | grep ts3server_ > /dev/null
CHECK=$?
[ $CHECK -eq 0 ] && echo "$DESC is UP" || echo "$DESC is DOWN"
;;
*)
echo "Usage: $0 {start|stop|status|restart}"
exit 1
;;
esac
exit 0
I want connect in the screen, but I got this.
Cannot open your terminal '/dev/pts/0' - please check.
Did I do something wrong?
This happens because you may have done a sudo su user_name and then fired the screen command.
There are 2 ways to fix this.
script /dev/null as the user user_name and then type
screenTo solve the problem try running script /dev/null as the user you su to before launching screen.
script -q -c "su $USER -l -c \"screen -m -d -S $NAME $DAEMON start\"" /dev/null
More on it:
Inspired by both endorsed answers here I added the following function to my .bashrc:
sscreen(){
script -q -c "screen $*" /dev/null;
}
Now I just use sscreen instead of screen and never have to think about the issue again.
