I am facing a vague issue while trying to make two process talk to each
other using named pipe.

The process which reads, basically creates FIFO using

I want to copy the contents of a named pipe to a file. I have tried using:
cat pipe.p >> transcript.log

Also strange was that when I did the command above, cat did not return control back to the shell. Why?

touch test.file
LOG=./tmp.log

PIPE=./tmp.pipe
mkfifo ${PIPE}
trap "rm -f ${PIPE}" EXIT
tee -a ${LOG} < ${PIPE} &
