Description Robert Easterling 2000-01-26 14:01:04 UTC 
The read command does not receive the data from a pipe, e.g.

ksh-\1> echo "test" | read x
ksh-\2> echo $x

ksh-\3> read x
test
ksh-\4> echo $x
test
ksh-\5>

As you see in the second attempt without the pipe, read gets
the input string and assigns to variable x.  Both will work
on HP-UX and on SunOS.

This happens with bash too, FWIW.
Comment 2 Trond Eivind Glomsrxd 2000-04-06 22:51:59 UTC 
It works with zsh - the author of pdksh is aware of the problem:

Comment 3 Trond Eivind Glomsrxd 2000-08-02 13:56:07 UTC 
The author is of the opinion that this is undefined behaviour in the POSIX spec.
Closing.
