Just got it. As regan pointed out, I had to add the user to the sudoers group. But the main reason was I’d forgotten to update the repositories cache, so apt-get couldn’t find the sudo package. It’s working now. Here’s the completed code: FROM ubuntu:12.04 RUN apt-get update && \ apt-get -y install sudo RUN … Read more
As of Emacs 24.3, an analog of the old multi: syntax has been layered on top of the modern tramp-default-proxies-alist approach, meaning that you can once again perform multi-hops without any prior configuration. For details, see: C-hig (tramp)Ad-hoc multi-hops RET With the new syntax, each ‘hop’ is separated by |. The example in the manual … Read more
Try: subprocess.call([‘sudo’, ‘apach2ctl’, ‘restart’]) The subprocess needs to access the real stdin/out/err for it to be able to prompt you, and read in your password. If you set them up as pipes, you need to feed the password into that pipe yourself. If you don’t define them, then it grabs sys.stdout, etc…

In order to fully understand Linux file permissions you can study the documentation for the chmod command. chmod, an abbreviation of change mode, is the command that is used to change the permission settings of a file.

Ok it looks like NPM is using your .gitignore as a base for the .npmignore file, and thus ignores /lib. If you add a blank .npmignore file into the root of your application, everything should work. A better, more explicit approach is to use an allow-list rather than a disallow-list, and use the “files” field … Read more
The -S switch makes sudo read the password from STDIN. This means you can do echo mypassword | sudo -S command to pass the password to sudo However, the suggestions by others that do not involve passing the password as part of a command such as checking if the user is root are probably much … Read more
Much simpler: use sudo to run a shell and use a heredoc to feed it commands. #!/usr/bin/env bash whoami sudo -i -u someuser bash << EOF echo “In” whoami EOF echo “Out” whoami (answer originally on SuperUser)
In :w !sudo tee %… % means “the current file” As eugene y pointed out, % does indeed mean “the current file name”, which is passed to tee so that it knows which file to overwrite. (In substitution commands, it’s slightly different; as :help :% shows, it’s equal to 1,$ (the entire file) (thanks to … Read more
try running: su -c “Your command right here” -s /bin/sh username This will run the command as username given that you have permissions to sudo as that user.
Generators are designed to be installed globally. Otherwise, you always have to install the generator you’re about to use in each project, which is unnecessarily painful. Also, you don’t get to see the lovely yo menu which lists you all the available generators (unless of course, you install them all locally): Setting up npm for … Read more
