Muzete pouzit expect, priklad /usr/share/doc/expect/examples/timed-read:

#!/bin/sh
# \
exec expect -f "$0" ${1+"$@"}
# read a complete line from stdin
# aborting after the number of seconds (given as an argument)
# - Don Libes
set timeout $argv
expect -re \n {send_user $expect_out(buffer)}

v bashi pak neco jako:
answer=`timed-read 10`

Doporucuji projit i ostatni priklady k expect, je to uzitecny program.
