Hi, I think , I have not explained it correctly, in the first mail. I mean that "echo "service httpd status"> /dev/pts/2", is executed in first terminal(/dev/pts/1), and the output is redirected to the /dev/pts/2.
That is correct. The "echo" command will execute in the terminal into which you entered the command, and the output ("service httpd status") will be redirected to /dev/pts/2.
Here /dev/pts/2 is the terminal of another machine to which we are connnected and is a virtual machine. But the output directed here is a command, so what happens is that, the output of the first terminal, is actually executed as a command in the /dev/pts/2 terminal, because the output is redirected directly to the terminal.
That is not correct, and also contradicts your previous statements. Please test this again. Redirecting output to a different tty will not cause a command to be executed there.
And I know the pty of the first terminal, I got it by command "tty". Now, my requirement is that, after the command "service httpd status" is executed on the /dev/pts/2. I want to redirect or get the output on the first terminal(/dev/pts/1).
Why do you need to execute a command in /dev/pts/2 without entering the command there?
