Clearing the standard input in shell script
 
I have a shell script, having more than one user input.
I want to clear/flush the stdin before the read command, as it is creating problem if user pressed more than one enter key for one read.

Code:
#!/bin/sh

echo "Give input"

read -p ":>" FirstInput

sleep 1

echo "Given value: $FirstInput"

# Here I want to flush the input before reading the user input again.

read -p ":> " SecondInput
echo "Given value: $SecondInput"

You might try to put
Code:
read -t0
after the first read statement (before sleep). In this way any other additional input is immediately and silently ignored.
