Why is the output of wall command not displaying in stdout?
Multi tool use
5
I am using ubuntu 14.04. I'm executing the wall command like this:
$ wall
Hi this is for testing
^d
But it doesn't display the message in terminal. I'm just executing the wall command in my machine; I'm not sending it to anyone. How could I solve this problem?
Thank You...

Test it in TTY . I had the same issue in 16.04 , where it doesn't display in GUI but does display in TTY. I suspect it may be a form of bug

Can you run it with strace so we see if it has any permissions issues perhaps?strace -e open wallshould list numerous open(2) calls, and the last one should be something likeopen("/dev/pts/0", O_WRONLY|O_NONBLOCK|O_LARGEFILE) = ...

I tried it, but it doesn't show that path. Instead of that it gives like this,open("/var/run/utmp", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = 3 +++ exited with 0 +++

Type the mesg command, and if it says "is n" (messages from wall are blocked), do mesg y. Of course, do man mesg;man wall first.
