You can also restrict the number of characters to read using “-n” option like following. Following option “-n1″ make read command to expect one character as input.

bash# read -n1 -p “Would you like to continue (y/n)? ” choice
bash# echo $choice

Similarly you can set timeout for input using “-t” option. In the following example, the read wait for 5 seconds for input using “-t5″ option.

bash# read -t5 -n1 -p “Would you like to continue (y/n)? ” choice
bash# echo $choice

You can combine both echo and read command using “-p” option with read command.

For example:
read -p “Which color you like the most (red/green/blue)? ” color
echo Your choice is $color
