Cask allows you to easy install Mac OS GUI apps and binaries directly from the command line using Homebrew.

What you do want to do is to tune your shell: This is a bash shell installed via MacPorts and enhanced by Powerline and dir.But while both these forms of backup serve important purposes, I also recommend maintaining a clone (also known as a bootable duplicate)—a complete, identical copy of your startup volume, stored on an external drive in such a way that you can boot your Mac from it if necessary. Hands down: Terminal.app While there are others, they do offer little to no advantage and just clutter your search results. ITerm2 iTerm2 is a free and open source terminal emulator that offers users a robust search tool coupled with auto-complete commands, multiple panes in independent.

Basic Terminal Commands for Mac OS X. For example, once you have cask, if you want to install Chrome from the command line, then Cask can do that with with a command like.
![]() The Best Terminal App Free And OpenEvery file on your drive—including thousands of hidden files—must be copied just so, with permissions and other metadata intact. (Your Mac’s built-in OS X Recovery features include Disk Utility, but sometimes you need a drive-repair app with more oomph.) Finally, having a clone is essential when upgrading to a new version of OS X, because it gives you the option to easily revert to your previous system (by erasing your upgraded-OS drive and then restoring from the clone) if compatibility problems arise.Unfortunately, you can’t make a clone merely by copying files from your startup volume to an external drive in the Finder. By contrast, even though Time Machine also backs up every file on your drive, restoring all those files to a new drive takes hours (or possibly days) restoring an entire drive from an online backup service takes even longer.A clone also comes in handy for troubleshooting, because you can use it to run third-party utilities on your ailing drive. A few moments later, you’re back up and running—and you can then repair (or replace) your main startup drive more or less at your leisure. You simply attach your clone drive, restart while holding down the Option key, select the clone drive in OS X’s Startup Manager, and press Return. Each has a long history, focuses on cloning, presents a simple and clear user interface, and includes unusual features that make it an especially good choice for creating and maintaining bootable duplicates.For everyday cloning tasks, SuperDuper and Carbon Copy Cloner are equally good in almost every respect, and they have a core set of features in common. Most of these apps and processes do an entirely respectable job, but two cloning utilities—Shirt Pocket’s $28 SuperDuper and Bombich Software’s $40 Carbon Copy Cloner—stand above the rest. (You can see a list in the online appendix to my book Take Control of Backing Up Your Mac.) It’s also possible (if not especially convenient) to clone a drive using Disk Utility or by using the diskutil command in Terminal. (For more details, read Mike Bombich’s article What makes a volume bootable?) All this is best done with a utility designed expressly for cloning.More than two dozen third-party backup apps can make bootable duplicates. And, crucially, the System folder (/System) on the backup drive must be “blessed,” which entails recording its physical location on the drive in a special portion of the drive’s hidden HFS Volume Header. Carbon Copy Cloner also offers encryption for disk images, while SuperDuper lets you choose from three levels of compression. (The free trial version of SuperDuper disables the incremental update feature, which Shirt Pocket calls Smart Update.) Both also let you deselect specific files, folders, or filename patterns to omit them from your backup, although they have very different interfaces for doing so—I find this task much easier to accomplish in Carbon Copy Cloner than in SuperDuper.In addition to using an actual drive as the destination, each app can copy the source volume to a disk image (which won’t itself be bootable, but which can be restored to a drive that will then become bootable) you can choose from among several disk-image formats, with or without compression. Each utility provides a plain-English summary of what’s about to happen you then click a button to begin the copying operation.Both apps give you the option to erase the destination before copying files from the source or to update your clone incrementally to reflect only those files that are new, changed, or deleted since the previous cloning run. Because so many files are merely being linked rather than copied, a Sandbox clone takes much less time to create than a regular clone, and it occupies less space on the destination drive. Instead, SuperDuper creates symbolic links of those items from the source to the destination. When you create a clone using the Sandbox option, the contents of the source volume’s /Users folder (and, optionally, the non-Apple apps in the /Applications folder) aren’t copied to the destination. (In Carbon Copy Cloner, such actions can be specified only for scheduled tasks.)SuperDuper has two post-run options that Carbon Copy Cloner lacks: It can create a disk image of the destination volume (useful in an institutional setting where you may need to copy an image to multiple Macs), and it can install a package-based app on the destination.In addition, SuperDuper has a feature called Sandbox, which requires some explaining but turns out to be very useful in certain situations. (For example, I update my iMac’s clone twice a day, since its destination drive remains connected all the time, but my MacBook Pro’s clone updates only when I plug in my backup drive.)Both apps can also perform designated tasks—for example, running shell scripts ejecting the destination drive on completion or instructing your Mac to sleep, shut down, or restart—before or after a cloning operation. Both apps also let you schedule backups to run unattended—on a recurring schedule, when the destination drive is mounted, or both. The developer also recommends against restoring a Sandbox clone to the original drive.Although Carbon Copy Cloner lacks a Sandbox feature, it has four other unique capabilities that you may find even more helpful.Recovery HD support When cloning a volume, Carbon Copy Cloner can duplicate the hidden Recovery HD partition that’s created when you install OS X 10.7 Lion and later—this is the hidden partition that makes OS X Recovery possible. SuperDuper’s documentation cautions that you should not treat a Sandbox clone as a replacement for a regular clone, but as a supplement for testing purposes. (Note that if you use the “Sandbox – shared users and applications” option, updates made to linked third-party apps while running from the clone will affect the original drive.) This makes a SuperDuper Sandbox a great way to test, say, a beta version of OS X. However, you can also feel secure knowing that any changes you make to documents and settings while working from the clone will also show up when you switch back to the original drive. But any changes to the contents of /Users (such as modifications to documents in your home folder) are made on the original drive, not the clone.What’s the point of all this? For starters, you can safely do anything you like while booted from the Sandbox clone—upgrade OS X, install new software, try out wacky system customizations, or whatever—and none of those changes will affect your original drive. Eset nod32 antivirus for mac free downloadThose folders maintain the original drive hierarchy—so, for example, if a file was originally located in /Users/jk/Documents, it’ll be found in /_CCC Archives//Users/jk/Documents afterward. When you use the “Preserve newer files, don’t delete anything” option, Carbon Copy Cloner moves any items that have been deleted from the source volume, and older versions of items that have been changed, into a date-and-time-stamped subfolder of a new _CCC Archives folder at the top level of your destination drive. But Carbon Copy Cloner has a mode that attempts to give you the best of both worlds. In addition, if you ever need to erase (or replace) your internal drive and restore it from a clone, Carbon Copy Cloner enables you to restore the Recovery HD partition as part of the process with SuperDuper, you’d have to run the OS X installer again to recreate that partition.Archiving Versioned backups (such as those created by Time Machine and CrashPlan) normally are not bootable, and bootable clones normally contain only the most recent versions of your files. For example, if you want to encrypt the external drive using FileVault, that drive must have its own Recovery HD partition. But having a Recovery HD partition on an external drive can come in handy.
