It's a surprise why now
tail -f isn't working while earlier was.
I've the below command to run for backup.
ubuntu@ubuntu:~$ sudo tar -cvf /media/ubuntu/My*Linux/ub*data/zebra.tar /media/ubuntu/home > z1 2> z2 && echo "pass" || echo "fail"
To see the output and error, there are those 2 files
Now I want to see the output of the command on a terminal from file z1:
ubuntu@ubuntu:~$ tail -f z1
but this command is not showing the data that's getting appended with time.
I'm working on live install of Ubuntu 14.04.1 using usb pen drive. Can this be the reason?
