Poll results: How do you pronounce zsh?

 

A week ago I posted a poll asking how to pronounce zsh, well the results are in.

zshPollresults

Well, the winner is Zeeshell (pronounced like seashell), however this is clearly not unanimous.

Several readers also pointed out this thread on StackExchange What are the practical differences between Bash and Zsh? which contains lots of useful information.

Poll How do you pronounce zsh?

 

The poll results are here.

As people migrate to Catalina there is an option to update your default shell.

zsh is the new default shell for new users (bash is the default shell in macOS Mojave and earlier), so if you are upgrading you may want to change your default shell to zsh.

Paul Falstad wrote the first version of Zsh in 1990[6] while a student at Princeton University.[7] The name zsh derives from the name of Yale professor Zhong Shao (then a teaching assistant at Princeton University) — Paul Falstad regarded Shao's login-id, "zsh", as a good name for a shell.

A delightful community-driven (with 1,300+ contributors) framework for managing your zsh configuration. Includes 200+ optional plugins (rails, git, OSX, hub, capistrano, brew, ant, php, python, etc), over 140 themes to spice up your morning, and an auto-update tool so that makes it easy to keep up with the latest updates from the community.

So while it was pretty obvious how to pronounce "Bash" (The shell's name is an acronym for Bourne-again shell, a pun on the name of the Bourne shell that it replaced), but what about "zsh"?

Top 12 unix commands for data scientists.

 

A really useful post on KDnuggets.

With the beautiful intuitive interface it is sometimes easy to forget that Mac OS X has unix underpinnings and that the Terminal gives access to whole set of invaluable tools.

This post is a short overview of a dozen Unix-like operating system command line tools which can be useful for data science tasks. The list does not include any general file management commands (pwd, ls, mkdir, rm, ...) or remote session management tools (rsh, ssh, ...), but is instead made up of utilities which would be useful from a data science perspective, generally those related to varying degrees of data inspection and processing. They are all included within a typical Unix-like operating system as well.

If you regularly have to deal with very large data files some of these commands will be invaluable, for example:

head outputs the first n lines of a file (10, by default) to standard output. The number of lines displayed can be set with the -n option.

head -n 5 my file.txt
