I know that this question is answered many times, but I still can't figure out how to do it. Maybe it's because I don't know the correct keyword to search for.
Using
echo -ne '\n' | enter
doesn't work. My code is:
#! /bin/bash
#Grub-customizer
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
echo -ne '\n' | return
sudo apt-get update
sudo apt-get install grub-customizer
You're supposed to pipe the \n into the command that's going to be receiving it (otherwise it won't ever see it!):
echo -ne '\n' | sudo add-apt-repository ppa:danielrichter2007/grub-customizer
echo -ne '\n' | sudo apt-get install grub-customizer
Now, the right solution here would instead be to use the -y flags instead:
sudo add-apt-repository -y ppa:danielrichter2007/grub-customizer
sudo apt-get install -y grub-customizer
/dev/tty? Might be better to more strongly reinforce the -y flag advice, which is a much more sure thing.
stdin in most cases, but DEBIAN_FRONTEND could definitely break using echo.
echo -ne '\n' is a faithful copy from the problem description, the idiomatic way to write that is just echo.-y solution as the main answer, and the echo fix as a tangential comment.'echo -ne "\n" | ./create.sh \n', // this command is for pressing enter each time the shell script is asking user to press enter
'echo -ne "\n" | yourcommand \n', //tempate
const client = new Client();
const cmds = [
'ls -lah \n', // \n is important
'cd /mnt \n',
'echo -ne "\n" | ./create.sh \n', // this command is for pressing enter each time the shell script is asking user to press enter
'pwd \n',
'ls -lah \n',
'exit \n',
];
client.on('ready', () => {
console.log('Client :: ready');
client.shell((err, stream) => {
stream.on('close', (code) => {
console.log('stream :: close\n', { code });
}).on('data', (myData) => {
console.log('stream :: data\n', myData.toString());
}).on('exit', (code) => {
console.log('stream :: exit\n', { code });
client.end();
}).on('error', (e) => {
console.log('stream :: error\n', { e });
rej(e);
});
for (let i = 0; i < cmds.length; i += 1) {
const cmd = cmds[i];
stream.write(`${cmd}`);
}
});
}).connect({
host: '127.0.0.1',
port: 22,
username: 'root',
password: 'root',
});

echo | some_command, you can get either the exit status ofechoor the exit ofsome_command, depending on how your shell is currently configured. You get much, much more consistent and reliable results by just invokingsome_commandin such a way that it doesn't read from stdin at all.entercommand of which you speak? Also,returnpretty much ignores it's standard input, so piping something into it doesn't accomplish much...
