Java Read input data within a specified period of time

Hi All,

I am working on a script which requires an input from user within one 1 min.

So if the user gives the required input within 1 min., it will execute on the basis of input provided by the user.Other wise it will execute on a default value(hard coded inside the script).


Now, I am able to hard code the default input, but I get stuck when I need to pass the input within 1 min.

I am not sure how to specify the time period within which it gets input from the user.If doesnot get the user input within 1 min, it executes on the default values.

May be I have to use sleep command in loop to get this done, but I am not sure at this moment.!!


Any body having any idea, how this can be done?
BTW, I am using AIX 5.3, working on k-shell.
Appreciate ur efforts.
Regards,
raj.

The read command in KSH has a switch to define a timeout (-t). Example usage:
Code:
echo "Input (timeout 10 seconds):"
read -t 10 userinput
if [ $? -ne 0 ]
then
    echo "Using default value"
else
    echo "Using user input"
fi

I have named the script as delay.sh and It gives the following error.
Code:
Error:
bsd:dir1/users/usename/Files>sh delay.sh
Input (timeout 10 seconds):
delay.sh[3]: read: 0403-010 A specified flag is not valid for this command.
Using default value

How can I fix the error?
Regards,
raj.

It works when I run the script as ksh93 delay.sh.
I waits for 10 seconds... and in the mean time user gives input....It proceeds on the basis of that else i takes default value.

Thanks a lot for ur help.Appreciate ur effort and time.
Cheers
raj.

If you don't hit enter, how is read supposed to know that all input has been read?
# 7  
If u want to catch only some number of characters (i.e. only 2 or only 5 characters need to be entered and than your standard input should be disabled) than I have perl code if u have perl installed in your machine.
