OSX - Function to list all members for a given group

Group membership in OS X is a mish-mash of standards that end up meaning there's almost a half-dozen of ways to belong to a group, what with group inheritance and automatic assignment. This means there's no easy command to find out all groups a user belongs to. The only sensible way then is to list all users and then query each user for membership. NOTE: This is a function. Once input you can execute it by calling with a groupname. Show Sample Output

```

Unlike the other ones this also displays the short description so you can see what that package does without having to go to google. It also shows the largest packages on top. You can optionally pipe this through head to display an arbitrary number of the largest packages installed (e.g. ... | head -30 # for the largest 30 packages installed) Show Sample Output

A formatting test for David Winterbottom: improving commandlinefu for submitters

Commandlinefu.com is great but has a few bugs when people are submitting new commands: . 1. There is no preview button. This was a minor inconvenience before, but now is a major problem since new commands won't show up to be edited until they have been moderated. . 2. White space in the description field and in the comments is almost completely lost. People resort to using periods in between paragraphs to force a line break. Indentation of code is ridiculous. . 3. Many characters get munged. . 3a. For example, a less than character in the description gets read as an HTML tag and discarded. In order to type a less than, I've had to type "<" (I hope that comes out right). Unfortunately, when re-editing a command, the HTML entity is turned into a literal less than character, which I have to change back by hand before saving. 3b. Some unicode characters work in the description field, but turn into ugly literal HTML strings when put in the sample output or in an additional command using the $ prefix. . For example, here is a unicode character: ❥ $ Here is the same character after a dollar sign: ❥ . 3c. Some unicode characters don't work anywhere. Bizarrely, it appears to be the most commonly needed ones, such as Latin-1 accented characters. Here are some examples, . Bullet: ?, Center dot: ?, Umlaut u: ?. . 4. Here is an example of the greater than, >, and less than,
