This does not make a lot of sense.
So-rry your Unix-ness...
I should have been more specific & I apologize: I'm still very new to Unix. I meant to say that on the machine I work on, I (as a user) can only use MKFIFO.
If I do `mknod bla`, I get an error message "mknod: must be super-user". BTW, I tried to do the same thing as you did: it did not work.
[dev1@la]/home/dev1% mknod bla p
[dev1@la]/home/dev1% cat bla &
[2] 23119
[dev1@la]/home/dev1% echo "hello world" > bla
ksh: bla: cannot create
I am working in my /home directory. What am I doing wrong?
