Sometimes when we run a script or command they ask for "yes" or "no" or ask to press the
Return or Enter key to continue the operation.
To automate the
Enter key or say
yes one of this:
yes '' | <your_command_here >
echo | <your_command_here >
You can put the above in a bash script to run the command.
If want to press the
space bar do:
echo -n " " | <your_command_here >
The -n flag tells echo not to issue a newline after the string.
