I've created a really simple bash script that runs a few commands. one of these commands needs user input during runtime. i.e it asks the user "do you want to blah blah blah?", I want to simply send an enter keypress to this so that the script will be completely automated.
I won't have to wait for the input or anything during runtime, its enough to just send the keypress and the input buffer will handle the rest.
You can just use yes.
# yes "" | someCommand
You might find the yes
command useful.
See man yes
You could make use of expect (man expect comes with examples).
Here is sample usage using expect
:
#!/usr/bin/expect
set timeout 360
spawn my_command # Replace with your command.
expect "Do you want to continue?" { send "\r" }
Check: man expect
for further information.
