command-line Getting started with command-line
Remarks
This section provides an overview of what command-line is, and why a developer might want to use it.
It should also mention any large subjects within command-line, and link out to the related topics. Since the Documentation for command-line is new, you may need to create initial versions of those related topics.
Hello world
In Unix/Posix systems:
>$ echo "Hello World!"
This simple command will print Hello World on the terminal.
Installing ZSH as default shell on macOS
The simplest way is to use brew :
brew install zsh
After installation, you may want to set it as your default shell by doing:
sudo echo '/usr/local/bin/zsh' >> /etc/shells
chsh -s /usr/local/bin/zsh
If you have git, and required command line tools installed you can compile and install the latest version (5.2 as of this edit) as follows:
# clone the source
git clone git://git.code.sf.net/p/zsh/code zsh
# checkout the required version, say, zsh-5.2
cd zsh && git checkout zsh-5.2
# check the documentation for help on configuration options
./Util/preconfig
./configure --prefix=/usr/local \
--enable-fndir=/usr/local/share/zsh/functions \
--enable-scriptdir=/usr/local/share/zsh/scripts \
--enable-site-fndir=/usr/local/share/zsh/site-functions \
--enable-site-scriptdir=/usr/local/share/zsh/site-scripts \
--enable-runhelpdir=/usr/local/share/zsh/help \
--enable-etcdir=/etc \
--mandir=/usr/local/share/man \
--infodir=/usr/local/share/info \
--enable-cap \
--enable-maildir-support \
--enable-multibyte \
--enable-pcre \
--enable-zsh-secure-free \
--with-tcsetpgrp
# compile and check if compiled successfully
make -j5 && make check
# you should see results of successful test scripts
sudo make install
Again, you can make zsh as your default shell by adding it to /etc/shells and using chsh as described above.
macOS using homebrew
brew install zsh
sudo echo '/usr/local/bin/zsh' >> /etc/shells
chsh -s /usr/local/bin/zsh
