fish Shell : The Friendly Interactive Shell

Advertisement

fish Shell is Really a Friendly Interactive Shell Which Be Used on GNU/Linux, OS X or UNIX Systems. fish is a user-friendly and Exotic Shell. Previously we have talked about UNIX Shell, Terminal and Terminal Emulators for providing the basic idea. On OS X, we usually use oh-my-zsh with iTerm2 and Homebrew as package manager. That oh-my-zsh can be replaced with fish Shell or at least can be tested for usability.

 

fish Shell : Basics

 

Exotic as the syntax are not from Bourne shell or C shell and certain features are enabled by default. Navigate to fishshell dot com on your browser to check the features of this Shell. It is possible to use fish on Windows with Cygwin. For general purpose, we are describing the basic usage of fish shell with OS X fish shell App, it is portable, no installation is needed. This will install fish on OS X (be careful, its not the portable one) :

Vim
1
brew install fish && echo "/usr/local/bin/fish" | sudo tee -a /etc/shells

For Debian 8.0, we will install in this way :

wget http://download.opensuse.org/repositories/shells:fish:release:2/Debian_8.0/Release.key
apt-key add - < Release.key  
echo 'deb http://download.opensuse.org/repositories/shells:/fish:/release:/2/Debian_8.0/ /' >> /etc/apt/sources.list.d/fish.list
apt-get update
apt-get install fish

If you change Debian_8.0 to Debian_7.0 for Deb 7.0.

fish Shell - The Friendly Interactive Shell

 

fish Shell : OS X Basic Usage For Testing

 

If you have downloaded that App for OS X on Desktop and your username is abhishekghosh, then if you run :

Vim
1
exec '/Users/abhishekghosh/Desktop/fish.app/Contents/Resources/base/bin/fish'

on iTerm2, instead of oh-my-zsh, you will be using fish shell portable version. It will give you the information to type help as command and hit the return key. It will open the webpage on default browser instead of normal command line options. It is optimized for GUI. Now, if you type :

Vim
1
brew install

You’ll see that you are getting automatic suggestions or incremental search. If you run ls -al command, you’ll feel that it is very fast. It is POSIX compliant shell, so normal usage like :

Vim
1
2
set abhishek abhishek-ghosh
echo $abhishek

You’ll get abhishek-ghosh as return. fish has good syntax highlighting with error checking feature. Other things are written in the official website. We provided the basic idea.
