What is iTerm2 for Mac
iTerm2 for Mac is a command-line tool that replaces the default Terminal command line once installed on the computer. iTerm2 on Mac is supposed to add new features to the default Terminal app and make it easier to use and work with.
The default Terminal app that Macs have by default in their Utilities folder gets the job done, but if you are someone who needs to frequently work with a command line, then there are ways to make your work more efficient. One of those ways is to install iTerm2 on your Mac. This app basically enhances the base Terminal functionality and adds an array of new and really helpful features that can help make your work easier, more effective, and more efficient. We will have a quick look at some of those features below, and then we will tell you something about installing and setting up iTerm2.
iTerm2 on Mac Features
iTerm2 on Mac is a powerful tool that replaces the built-in Mac Terminal, introducing to it a variety of improvements. If you need to use the Terminal command line of your Mac on a regular basis, installing iTerm2 on your Mac can be very helpful.
Here is a quick overlook of some of the many benefits and additional features that come with installing iTerm2:
This feature lets you separate any given tab into several panels, each of them with a different session shown in it – perfect for multitaskers and people who are working on large projects with many different moving parts
iTerm2 also has a nifty search too, that always stays on top of all other windows, so that it’s never obscured by the iTerm2 UI. The Search tool quickly highlights all matching phrases in a given panel and has regular expression support.
You can set a designated keyboard shortcut for iTerm2 that lets you summon an iTerm2 window with the press of that keyboard combination, no matter what app you are using at the moment. You can even specify which iTerm2 window will open with which keyboard shortcut.
This feature does exactly what its name suggests – with iTerm2, you have the option to see the history of text you’ve recently copied and/or pasted in iTerm2. There’s even the option to export that history to a file on your drive.
A window with suggestions pops open every time you start typing a word that has already appeared in the current Terminal window. The algorithm of this feature seems to be quite effective, as it usually manages to correctly guess what you are trying to type by putting that word/phrase on the top of the suggestions list.
This feature allows you to use keyboard combinations to edit the text in a Terminal window.
There is a huge variety of ways you can customize and configure the iTerm2 Terminal so that it best suits your needs and preferences.
With Instant Replay, you can revisit past moments of a given Terminal window and thus recover any text you’ve deleted but now want to restore.
…and many more!…
The features we’ve mentioned thus far are only a small portion of all the great improvements that iTerm2 brings to your base Terminal command line. The app tool is very easy to install and can be downloaded for free, so if you tend to spend a lot of time working with the Terminal of your Mac, we highly recommend getting iTerm2 to make your work easier, faster, more efficient, and more effective.
Is iTerm2 only for Mac?
iTerm2 is only available for Mac systems – it cannot be used on Windows or Linux systems. iTerm2 can only be installed on Macs that run on macOS 10.14 or later – the tool can be downloaded for free from its official site.
iTerm2 is specifically designed to serve as a Terminal replacement, which is why it’s not available on other operating systems. If you are a Windows or a Linux user, there are other tools that can help improve the functionality of your base command-line tools. For Mac users, who wish to get iTerm2 installed on their Macs, note that your Mac’s operating system must be 10.14 (macOS Mojave) or newer. If you are running on an older macOS release, upgrade to a newer one that’s compatible with iTerm2 in order to be able to use that tool.
