ZSH is a shell designed for interactive use, although it is also a powerful scripting language. Many of the useful features of bash, ksh, and tcsh were incorporated into zsh.
ZHS is a shell for Unix systems that has been around since 1990 and is more sophisticated and configurable than most shells out there. There are lots of features, such as:
Context-based completion of many functions (like remote filename completion in ssh, makefile targets, configure scripts, and much more), which is highly configurable.A powerful programming language with complex pattern matching mechanism (a pattern like **/*(^/) matches all (non-hidden) files in all subdirectories, but not directories themselves).
Lots of CLI (Command Line Interface) options and bindkeys.
Loadable module support for adding builtin commands.
After installing vim and upgrading coreutils, the final piece of the puzzle was getting an up to date version of zsh installed.
I gave the version in the repos a go first, and it came back with version 4.2.6.
$ sudo yum install zsh $ zsh --version zsh 4.2.6 (x86_64-redhat-linux-gnu)
Unfortunately, that’s too old for me to use zsh-syntax-highlighting so it was time to compile from source again.
First, get and extract the files:
$ wget http://sourceforge.net/projects/zsh/files/zsh/5.0.2/zsh-5.0.2.tar.bz2/download && tar xvjf zsh-5.0.2.tar.bz2 && cd zsh-5.0.2
Configure, make and install:
$ ./configure && make && sudo make install
Check that it’s installed fine. It installs to /usr/local/bin/zsh:
$ /usr/local/bin/zsh --version zsh 5.0.2 (x86_64-unknown-linux-gnu)
If you want to use it as your login shell, you’ll need to add it to /etc/shells:
$ echo "/usr/local/bin/zsh" | sudo tee -a /etc/shells $ chsh -s /usr/local/bin/zsh
Log out and back in again, and you should be running zsh version 5.0.2.
