Capture data going through named pipe

Is there a practical and easy way to capture data going through a named pipe? I've tried wireshark, but it only accepts a specific data format. I've also tried cat, but I get mixed results.

Thank you

I would set up two named pipes and connect them with

tee -a pipe.log < pipe1 > pipe2

Then have the first app write to pipe1 and the second read from pipe2.

Alternatively you could connect them with

tee pipe2 < pipe1

To have the data piped to your stdout.

Nevermind, I found out how to read the data using shell scripts as described here:

http://www.linuxjournal.com/content/using-named-pipes-fifos-bash

while true
do
 if read line <$pipe; then
 if [[ "$line" == 'quit' ]]; then
 break
 fi
 echo $line
 fi
done
