Hi,

Following little (bash) shell-script many times causes a "Broken pipe"
(SIGPIPE) warning to be emitted by bash. Is this expected behaviour?

An example of the message:
./tc-pipe.sh: line 5: 3541109 Broken pipe             seq 1 2

The message is generated on the second pass through the loop.
Changing ``a b'' to ``a b c d e'' below, often prints the message 4
times.

=== Begin tc-pipe.sh ===
#!/bin/bash

for t in a b; do
 seq 1 2
done | head -n 1

==== End tc-pipe.sh ====

L8r,

Buzz.
