    Other programmers deal with the issue of number of characters by inserting a random number of asterisks for each key pressed. Then at least you know its accepting keyboard input.

    The other question is why you cannot sudo in Terminal as a standard user but need to be logged in as an admin user.

      Users with permissions to ‘sudo’ are stored in /etc/sudoers – which will generally contain a line allowing ‘admin’ users to run sudo.

      The permissions on /etc/sudoers is root read-only, so you’ll need to be in an ‘admin’ group to view it – but then only if you have permissions to run ‘sudo’.

      Try:

      cat /etc/sudoers

      and you’ll get:

      cat: /etc/sudoers: Permission denied

      Now if you’re in the ‘admin’ group, type:

      sudo cat /etc/sudoers

      ps. don’t be daft and try to edit /etc/sudoers with something like ‘nano’.

      You need to use ‘visudo’ – which locks the file against multiple simultaneous edits and opens up the file in the ‘vi’ or ‘vim’ editor.

      You can totally screw your system up if bugger up this file, which is highly likely if you’re unfamiliar with using ‘vi’ or the correct syntax the file requires.

      There is a way around this, as long as you know the credentials for an admin user. Just use the “login” command from the standard account to switch to an admin user in the Terminal. Then you can use sudo as much as you like. Use “exit” to get back to your standard user.

    This is so annoying. That and the fact that I can’t enter a blank password. I get so sick of having to go make a password just to enter a command.

    What I don’t understand is if its hidden/can’t enter a blank password “in the name of security,” who cares, I’m sitting in front of the computer. Who/what are they keeping it secure from? The guy looking over my shoulder?

      Yes actually, it may sound weird but this actually is designed to prevent password snooping from ‘the guy looking over’ your shoulder. The invisible password thing has been part of BSD and Unix since the 70’s, a very long relic. Nowadays, if you have a secure and reasonably long password, it may not be as important, but imagine an unscrupulous individual discovering someone had a 1 to 6 digit password? That would be easy to set that as a parameter and guess and/or run a dictionary file against the digit match, thus, this security measure exists. This is from AT&T and Unix, it’s in all Linux distros too, it’s not just Mac OS X or Apple.

      Why on Earth would you want a blank password? Don’t be lazy.

        “Why on Earth would you want a blank password? Don’t be lazy.”

        Because I’m very tired of having to look up a password for every little thing. The only important (for me) password is my bank’s. I’ve stopped using face book and other (likedin, etc.), because of passwords. So I use enter (CRLF) whenever permitted.

        Unfortunately, I thought my question [How does one find the password for sudo?] was being answered. Not incidentally, all the ones I’ve tried result in “try again”.

        The sudo password is the same as the admin / root password

        Try using an easy mnemonic to remember passwords. Even something like “IHatePasswords321” would be better than nothing.

    Unfortunately for me my password does not seem to work under OSX 10.11. I know I am typing it right but it still says “su: Sorry”.

      SO, if this helps anybody… First i had the admin password on my 10.8.5 mac set for the admin, so I would enter it, (wihtout seeing it as explained above) and it would still say sorry no..
      Then I changed it to no passoword and tried that. I went back to the system preferences/user/groups/ and under the column for the list of users and admin, where there is a + and a – symbol, next to that is a little settings wheel. I had done a fresh install of my OS, and there was no MASTER PASSWORD set, even though there was an admin password set. I set the master password, and VOILA! bingo, sudo password joy>>. it took a second to think about it, and then ran my command. booya

    I’m trying to delete stuff from my mac with the sudo command but when i reach the point where i need to enter the password in the terminal instead of the usual grey rectangle there is a key inside that won’t let me type anything even if i type the password (btw i know that nothing should appear) and then press enter it would say ‘sorry try again’
    Have you got any idea what my problem is????

    I did what you suggested but the computer told me my password could not be found and it printed my refused password
