$ ditto /path/to/source /path/to/destination Like rsync, ditto can be used to copy directory trees, preserving permissions, ownership, and metadata. It’s been included in OS X for quite some time, but remains relatively unknown. The ditto command is superficially similar to rsync, but in reality it’s a very different tool. ditto: Copy or merge directories or archives

You will then be able to rsync to the Mac over SSH, or use SSH to connect to a shell on the system. To enable SSH access on a Mac, open System Preferences, go to Sharing, and select Remote Login. Omit the trailing slash, and rsync will copy (append) the source directory to the destination directory, creating an additional directory level that you might not have intended. It indicates that rsync is to read files within the source directory and synchronize them within the destination directory. $ rsync -av -delete /path/to/directory1/ that the trailing slash is important here. You can also use rsync between different systems, as long as the remote system has rsync installed and is running SSH: $ rsync -avn -delete /path/to/directory1/ /path/to/directory2/ Or if you want to see which files would be copied or deleted, add an n: $ rsync -a -delete /path/to/directory1/ /path/to/directory2/ If you don’t want the files listed during synchronization, remove the v flag: $ rsync -av -delete /path/to/directory1/ /path/to/directory2/ If you want to make the directories exactly identical, you’ll need to instruct rsync to also delete files in /path/to/directory2/ that do not exist in /path/to/directory1/: This will make sure that any and all files in /path/to/directory1/ also exist in /path/to/directory2/.
$ rsync -av /path/to/directory1/ /path/to/directory/2/ If you have a need to keep two directory trees identical, using rsync on the local system is trivial: It’s immensely useful and has been a bastion of IT for many years. The rsync utility can synchronize directory trees between folders on the same system or between folders on a local and a remote system.
If your work takes you into the command line in concert with GUI apps, these two commands can definitely come in handy. It will use the grep command to extract only the lines containing the string foo. If you have that list of files in the clipboard from another app, you can process it on the command line with pbpaste: For instance, if you wanted to list all of the files in a directory that start with the letter "f" and put that list into the clipboard, you’d type the following:īoom - that output can then be pasted into any GUI app. The pbcopy and pbtaste utilities work in concert, allowing access to and from the system clipboards/pasteboards from the command line. pbcopy and pbpaste: Copy and paste to/from the clipboard You should find all of them useful and, in at least one case, even entertaining. Here’s a list of 10 handy utilities that allow you to perform many functions on your Mac from the command line. OS X has hidden gems that even power users might not know about. Although graphical interfaces can simplify many tasks, they can also complicate other tasks - and the command line comes to the rescue. Because OS X is built around a BSD core, you can bring over your fancy one-liners and skip the cumbersome GUI tools to do simple things like walking a directory tree, deleting every file older than 30 days, or pulling a list of files in the current directory that contain a specific text string. To those familiar with the Unix shell, the command line or terminal is a powerful tool to be used to facilitate many system functions and interactions. Of course, most likely they’re actually restarting a launchd service or deleting a plist file. For those users, this is usually when something has gone inexplicably wrong, and typing cryptic commands into the prompt seems the only hope for a cure.

For most casual users, the OS X command line, accessed via the Terminal app, is at least as murky and daunting as the Windows Command Prompt, to be used only in times of extreme distress.
