Hi
I found the line command which can read line from user input with timeout
but it work in Bourn shell so I can do it in C shell ??

Here an example

#!/bin/sh
replyBefor=AA
echo 'Enter string : \c'
reply=`line -t 5`
if [ "X" = "X$reply" ]
then
reply=$replyBefor
fi
echo
echo replyBefor = $replyBefor
echo "reply = $reply"

Thanks

In general, people are going to tell you not to bother with Csh scripting,
especially when you are considering a problem that is non-trivial even in
bourne shell.

If "line" has a "-t" option on your system (I have never heard of such
a thing) that performs a timeout mechanism, one may command:

set input = (`line -t 5`)

Otherwise there is no mechanism either builtin or possible by a hack of
programming that may accomplish such a task, with the remedial I/O
features csh provides.

It's *always* safer to do all your scripts in Bourne shell to ensure
greater compatibility. UNIX vendor's respective csh always tend to
differ in minor and irritating ways.
