In most cases, the `sudo` command error `unable to initialize PAM: No such file or directory` mostly appears when the pluggable authentication module file `/etc/pam.d/sudo` was edited with a typo or wrong pam module, etc.

## Via Single-User-Mode > Terminal
If you have an older Mac, you can boot into `single-user mode`, directly into the command line mode of macOS by skipping the UI:

* Press and hold down `COMMAND + S` keys until you see commands being executed in the Terminal.
* Open the `sudo` file with `vi /Volumes/Macintosh\ - Data/etc/pam.d/`, fix what's wrong, save and close the file by switching from `INSERT` to the `COMMAND` mode with the `ESC` key, type `:wq!`, and hit `enter`.
* Close the Terminal via the menu from the top of the screen
* Restart your machine

A leak-proof tee to the clipboard

This script is modeled after tee (see [man tee][2]) and works on Linux, macOS, Cygwin, WSL/WSL2

It's like your normal copy and paste commands, but unified and able to sense when you want it to be chainable.

This project started as an answer to the StackOverflow question: [How can I copy the output of a command directly into my clipboard?][3]

Modes

Vim has two modes insertion mode and command mode. The editor begins in command mode, where the cursor movement and text deletion and pasting occur. Insertion mode begins upon entering an insertion or change command. [ESC] returns the editor to command mode (where you can quit, for example by typing :q!). Most commands execute as soon as you type them except for "colon" commands which execute when you press the ruturn key.

Quitting

• :x Exit, saving changes
  
• :q Exit as long as there have been no changes
  
• ZZ Exit and save changes if any have been made
  
• :q! Exit and ignore any changes

HTML Tags You Can Use on GitHub

Wherever HTML is rendered on GitHub (gists, README files in repos, comments on issues and pull requests, ...) you can use any of the HTML elements that GitHub Flavored Markdown (GFM) provides syntactic sugar for. You can either use the syntactic sugar that GFM (or other GitHub-supported markup language you're using) provides or, since Markdown can contain raw HTML, you can enter the HTML tags manually.

But GitHub also allows you to use a few HTML elements beyond what Markdown provides by entering the tags manually, and some of them are styled with CSS. Most raw HTML tags get stripped before rendering the HTML. Those tags that can be generated by GFM syntactic sugar, plus a few more, are whitelisted. These aren't documented anywhere that I can find. Here's what I've discovered so far:
