Hello,
I have a problem with reads using timeouts. Either in shell, sub-shell or
script it seems "read with timeout" will only work once, i.e. if I have
multiple read with timeout statements only the first will be able to
timeout and the second will hang...
e.g.
*#/bin/bash*
*read -p "Enter first value : " -t 5 X*
*read -p "Enter second value : " -t 5 Y*
...
When executed:
./s3.sh
Enter first value : Enter second value
The second read doesn't timeout. This is bash 4.1.0
I have tried it in 4.1 and 4.2 and both reads timeout in both
versions of bash, both at the command line and in a script,
whether in a subshell or not.
