$ brew update - downloads upgraded formulas
$ brew upgrade [FORMULA...] - upgrades the specified formulas
$ brew outdated - lists outdated installations
Note updating all packages may take an excruciatingly long time. You might consider a discriminating approach: run `brew outdated` and select specific packages needing an upgrade.

PDF files are simultaneously wonderful and heinous. They are wonderful in being ubiquitous and mostly being cross platform. They are heinous in being very difficult to work with from the command line, search, grep, use only the text inside the PDF, or use outside of proprietary products.
xpdf is a wonderful set of PDF tools. It is on many linux distros and can be installed on OS X. While primarily an open PDF viewer for X, xpdf has the tool "pdftotext" that can extract formated or unformatted text from inside a PDF that has text. This text stream can then be further processed by grep or other tool. The '-' after the file name directs output to stdout rather than to a text file the same name as the PDF.
Make sure you use version 3.02 of pdftotext or later; earlier versions clipped lines.
The lines extracted from a PDF without the "-layout" option are very long. More paragraphs. Use just to test that a pattern exists in the file. With "-layout" the output resembles the lines, but it is not perfect.
xpdf is available open source at http://www.foolabs.com/xpdf/
Some commands (such as sed and perl) have options to support in-place editing of files, but many commands do not. This shell function enables any command to change files in place. See the sample output for many examples.
The function uses plain sh syntax and works with any POSIX shell or derivative, including zsh and bash.
Using this command you can track a moment when usb device was attached.
