Mac command line permission denied install#
When a command is shown on a line by itself as you might type it in a Terminal window, it follows a dollar sign that represents the shell prompt. Install the CRAN binrary Update XCode to 10.1, if you havent already Install the Xcode command line tools from the terminal. Luckily I had taken a snapshot of the other user's files about 2 hour before, and nothing was lost. You can use the doit command to get things done.
Just last week, someone overwrote someone else's files by running script in the wrong terminal session window (this was a very good and very experienced command line user). If you play in the Unix command space it is just a matter of "When", not "If" you are going to fumble finger a command and destroy something you instantly hope you have backed up. And various system at work, have critical files backed up to my iMac nightly (as I have about 7 terabytes of storage hanging off my iMac most of it for backups and backups of backups).
My iMac is backup via TimeMachine (hourly) and SuperDuper (daily), with some key files replicated to other systems nightly (for example the group web site hosted on my iMac). My MacBook is backup to my work iMac every workday. and even if you know what you're doing 🙂 Unless you know what you are doing with sudo, you should make sure you have a current backup. The ones who don't raise their hands are lying. Get a room full of unix system administrators and ask how many ever wipe out a system by executing something as root. Maybe the system is trying to keep you from doing something really bad. Sudo know why you're using it and if you expected a command to work as a regular user and it doesn't take a moment to think about why it didn't work. I don't want to sound overly melodramatic (well maybe I do) but
Mac command line permission denied mac os#
I honestly didnt expect to find it: I thought they might reserve that for the Server version of Mac OS X, but no, there it was, man page and all. I could of course go get it, but instead I took a look on my Mac. As quick as it took to hit the CR is as quick as the system is gone. Well, not on my main Linux server, because it apparently isnt important enough to install on spec. If you remove a file (or directory or even the root directory) it is gone, no changing your mind. There is no *system trash* to retrive things from. Sudo you are executing the command as root, as the systems supreme being. Sometimes a little knowledge can be a dangerous thing 😉 So any time I get "permission denied" I guess if I try command again with 'sudo' it should work.
