Let's say you have a bunch of .csv files in a folder. You want to merge them into one file. How to do that?

Download macOS Updates From the Terminal Without Installing. There’s no way, in the Mac App Store, to download an update manually without also triggering the installation. That’s annoying, but you can work around this using the Terminal. First, list all the available updates using softwareupdate -l, like we did above. Download Files Using Terminal. If you’ve a direct link of the file which you want to download, you can use the following commands to download the file using the Terminal on Mac. Cd /Downloads/ Note: If you want to download the contents to any other directory replace “downloads” with the directory name. Curl -O URL of file you want. The Windows Terminal is a modern, fast, efficient, powerful, and productive terminal application for users of command-line tools and shells like Command Prompt, PowerShell, and WSL. Its main features include multiple tabs, panes, Unicode and UTF-8 character support, a GPU accelerated text rendering engine, and custom themes, styles,. In the Terminal app on your Mac, use the mv command to move files or folders from one location to another on the same computer. The mv command moves the file or folder from its old location and puts it in the new location. For example, to move a file from your Downloads folder to a Work folder in your Documents folder.

Easy: use 'cat'

Cat is a UNIX program that lets you concatenate files, which is what we need. It's so simple that you don't need installable apps for it. For those who want the code first and the explanation later, here is the code:

That's it.

Translated, it says: 'take all files in this folder that end with '.csv', and put them in 'merged.csv' (effectively merging them).

Bonus tip: the 'open here in Terminal' service in Mac OS X 10.7+

It is important that this command is executed in the right directory. You don't want all existing .csv files in your entire computer to be altered this way, now do you? :) You can use the terminal to navigate to the folder (as described below), but you can also use a default Mac OS X service that functions in much the same way as its counterpart in Windows: 'open here in Terminal'. It works like this.

First, go to: System Preferences > Keyboard > Shortcuts > Services and select New terminal at Folder:

From now on, when you select a folder in the Finder, you can right-click and find it under Services:

We want more images!

Here are some images that may help. I had a bunch of .csv files that contained exports of Google search engine results (made by the SEOmoz toolbar). The English results were all put in a folder named en inside the folder /meta/csv:

I also made sure that every single .csv only contained the data I needed. In my case, I needed to delete the first 7 rows that were included in every export:

Back to the terminal. I used cd to go to that folder in my terminal (or use the 'New terminal at Folder' Service I described earlier):

You can see it below, i'm at macbook en (the folder en on my macbook) and my username is monchito. I then executed the command:

The file merged.csv was successfully added to the folder:

A quick check shows that the newly created .csv file contains way more rows than the individual files, so it probably worked :p

Now I can merge a great number of .csv files into one file quickly, and move on with my analysis.

What's next?

Since macOS is based on Unix there are a number of ways to compress files and folders within the filing system using Unix based application code, below are a few options using the Terminal or command line interface (cli). The default command line application interface in macOS is the Terminal and is stored in /Applications/Utilities.

File and folder compression saves on file size and ensures the contents are captured and delivered or stored as one monolithic file. A compressed file which contains files and folders is generally referred to as an archive. Here are some built-in compression applications you can use including zip, tar, gz, bz2, gz and dmg.

ZIP – Cross Platform

First up is ZIP one of the most commonly used compression techniques used across all platforms

To compress

To extract

If you want to make a zip without those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files, use the “-X” option in the command so:

TAR.GZ – Cross Platform

Second up is TAR, an old favorite on Unix/Linux – you add the GZ for the compression – compresses tighter than zip

To compress

To extract

TAR.BZ2 – Cross Platform

A variation on TAR GZ but with better compression than both tar.gz and zip.

To compress

To extract


Without the tar

To extract

DMG – macOS Only

This one is macOSnative only – for a GUI interface use /Applications/Utilities/Disk Utility – for command line use:

To create

To mount

  • UDZO – Compressed image (default)
  • UDRO – Read-only image
  • UDBZ – Better compressed image
  • UDRW – Read/Write image
  • UDTO – DVD disk image
