Hi,

I have a question regarding mknod. If I created a pipe file using
mknod eg. mknod filename p, how do I "unpipe" it, if there is such a
thing?

rm filename ?

I'm not quite sure what you mean, but...

If you want to delete it, just use 'rm'. Even if it's
made by 'mknod', it's just another file as far linux
is concerned.

If you meant how to "empty" the pipe after writing
to it, you just need something to read from it.
Example:

$ bunzip2 -c compressed_file.bz2 > named_pipe &
$ cat named_pipe

Of cource, there is no reason to use a pipe in
the above. You'll probably has to put the writing
to the pipe in the background (with &), as the pipe
gets "filled up", and don't accept any more until
it's "emptyed" by reading it.
