Z shell

Z shell (zsh) is a Unix command-line interpreter shell created by Paul Falstad.
==Description==
Z shell is similar to, but not completely compatible with, (zsh), with many additions to accommodate (csh) users while including some (tsch) features. Zsh supports editing of multi-line commands in a single buffer; variable editing; a command buffer stack; recursive bing; manipulation of arrays; and spelling correction. zsh uses GNU and should compile and run on any modern version and some older versions of Unix.. 1995-10-31.
===Zsh on macOS===
Bash had previously been the default command-line shell for Mac OS X since its NeXTSTEP origins. In 2019, Apple replaced bash with zsh in new installations of macOS Catalina (10.15). Upgrades to Catalina will retain the user's existing installation of bash with a notification in case the user would like to switch to zsh.Resources for Adapting to zsh in Catalina by Josh Centers, TidBITS. 2019-12-08.
