iTerm2 is a free and open-source terminal emulator for macOS, licensed under GPL-2.0-or-later. It was derived from and has mostly supplanted the earlier "iTerm" application.

Contents

iTerm2 supports operating system features such as window transparency, full-screen mode, split panes, Exposé Tabs, Growl notifications, and standard keyboard shortcuts. Other features include customizable profiles, Instant Replay of past terminal input/output, [2] [3] a Toolbelt showing running jobs and a command history, [4] the ability to open when a key combination is pressed, [5] and autocomplete. [6]

History

A Mozilla-sponsored 2019 code audit found one serious security vulnerability in iTerm2's tmux integration, which developer George Nachman fixed in an update. [7]

Reception

Software engineer Mike Rourke called it an "excellent [...] more full-featured Terminal" than Apple's built-in Terminal app. [4] iTerm2 is recommended in several programming books, [4] [8] [9] [10] with engineer Jo Rhett and Mozilla's Tom Ritter describing it as one of the most popular terminal emulators. [11] [12] Developer Mark McDonnel noted its additional features but criticized it for being less ubiquitous than tmux by lacking a Linux version. [13]

Xcode is Apple's integrated development environment (IDE) for macOS, used to develop software for macOS, iOS, iPadOS, watchOS, tvOS, and visionOS. It was initially released in late 2003; the latest stable release is version 15, released on September 18, 2023, and is available free of charge via the Mac App Store and the Apple Developer website. Registered developers can also download preview releases and prior versions of the suite through the Apple Developer website.

Datagram Transport Layer Security (DTLS) is a communications protocol providing security to datagram-based applications by allowing them to communicate in a way designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees. The DTLS protocol datagram preserves the semantics of the underlying transport—the application does not suffer from the delays associated with stream protocols, but because it uses User Datagram Protocol (UDP) or Stream Control Transmission Protocol (SCTP), the application has to deal with packet reordering, loss of datagram and data larger than the size of a datagram network packet. Because DTLS uses UDP or SCTP rather than TCP it avoids the TCP meltdown problem when being used to create a VPN tunnel.

seccomp is a computer security facility in the Linux kernel. seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit , sigreturn , read and write to already-open file descriptors. Should it attempt any other system calls, the kernel will either just log the event or terminate the process with SIGKILL or SIGSYS. In this sense, it does not virtualize the system's resources but isolates the process from them entirely.

<span class="mw-page-title-main">Crash reporter</span> System software that identify and report crash details

A crash reporter is usually a system software whose function is to identify reporting crash details and to alert when there are crashes, in production or on development / testing environments. Crash reports often include data such as stack traces, type of crash, trends and version of software. These reports help software developers- Web, SAAS, mobile apps and more, to diagnose and fix the underlying problem causing the crashes. Crash reports may contain sensitive information such as passwords, email addresses, and contact information, and so have become objects of interest for researchers in the field of computer security.

Apache Cordova is a mobile application development framework created by Nitobi. Adobe Systems purchased Nitobi in 2011, rebranded it as PhoneGap, and later released an open-source version of the software called Apache Cordova. Apache Cordova enables software programmers to build hybrid web applications for mobile devices using CSS3, HTML5, and JavaScript, instead of relying on platform-specific APIs like those in Android, iOS, or Windows Phone. It enables the wrapping up of CSS, HTML, and JavaScript code depending on the platform of the device. It extends the features of HTML and JavaScript to work with the device. The resulting applications are hybrid, meaning that they are neither truly native mobile application nor purely Web-based. They are not native because all layout rendering is done via Web views instead of the platform's native UI framework. They are not Web apps because they are packaged as apps for distribution and have access to native device APIs. Mixing native and hybrid code snippets has been possible since version 1.9.
