Oct 13, 2016 We’ve shown you a bunch of terminal tricks in macOS, all based on software that comes with the operating system itself. But you can do even more with the right free software, and thankfully, there’s a great package manager called Homebrew that lets you install loads of useful command line utilities. I suspect this is because the permission elevation is for the open command, not TextEdit itself. You should use a different editor that can have its binary run properly from the command line like SublimeText (sudo subl /path/to/file) or TextMate (sudo mate /path/to/file).Or just suck it up and use vi or nano:-). If you're going to be doing a lot of this type of thing TextEdit is probably the. 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).

Terminal (Terminal.app) is the terminal emulator included in the macOSoperating system by Apple.^[1] Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS.^[2]

As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command line interface to the operating system when used in conjunction with a Unix shell, such as zsh (the default shell in macOS Catalina^[3]).^[4] The user can choose other shells available with macOS, such as the Korn shell, tcsh, and bash.^[4][5]

The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) and later offers choices for values of the TERM environment variable. Available options are ansi, dtterm, nsterm, rxvt, vt52, vt100, vt102, xterm, xterm-16color and xterm-256color, which differ from the OS X 10.5 (Leopard) choices by dropping the xterm-color and adding xterm-16color and xterm-256color. These settings do not alter the operation of Terminal, and the xterm settings do not match the behavior of xterm.^[6]

Command Line Mac Os Terminal

Terminal includes several features that specifically access macOS APIs and features. These include the ability to use the standard macOS Help search function to find manual pages and integration with Spotlight.^{[citation needed]} Terminal was used by Apple as a showcase for macOS graphics APIs in early advertising of Mac OS X,^{[citation needed]} offering a range of custom font and coloring options, including transparent backgrounds.

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

TAR.BZ2 – Cross Platform

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

To compress

To extract

GZ

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:

Command Line For Mac Os X Terminal

To mount

To view

To Eject

You can also use a number of different formats for creating a .dmg

Macos Command Line Developer Tools

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

That’s the low down, the more common compression packages available will typically be covered in one of the above.
