This shell and command processor should be familiar if -you've used Linux (or older version of macOS) before. - -However, bash is not the only option. There are numerous other shells -that exist. Here are some popular examples: - -- [[https://en.wikipedia.org/wiki/Z_shell][zsh]] -- [[https://en.wikipedia.org/wiki/Fish_(Unix_shell)][fish]] -- [[https://github.com/ibara/oksh][oksh]] -- [[https://wiki.gentoo.org/wiki/Mksh][mksh]] -- [[https://en.wikipedia.org/wiki/Debian_Almquist_shell][dash]] - -While each shell has its differences, bash is POSIX compliant and the -default for many Linux users. Because of this, I am going to explore a -program called =bash-it= below that helps bash users increase the -utility of their shell without installing a completely new shell. - -** Installation -First, if bash is not already installed on your system, you can -[[https://www.gnu.org/software/bash/][download bash from GNU]] or use -your package manager to install it. - -For example, this is how you can install bash on Fedora Linux: - -#+begin_src sh -sudo dnf install bash -#+end_src - -If you are not using bash as your default shell, use the =chsh= command -to change your shell: - -#+begin_src sh -chsh -#+end_src - -You should see a prompt like the one below. If the brackets (=[]=) -contain =bash= already, you're done, and you can simply continue by -hitting the Enter key. - -If the brackets contain another shell path (e.g. =/usr/bin/zsh=), enter -the path to the bash program on your system (it's most likely located at -=/usr/bin/bash=). - -#+begin_src sh -Changing shell for <user>. -New shell [/usr/bin/bash]: -#+end_src - -You must log out or restart the machine in order for the login shell to -be refreshed. You can do it now or wait until you're finished -customizing the shell. - -#+begin_src sh -sudo reboot now -#+end_src - -* Bash-it -As noted on the [[https://github.com/Bash-it/bash-it][Bash-it]] -repository: - -#+begin_quote -Bash-it is a collection of community Bash commands and scripts for Bash -3.2+. (And a shameless ripoff of oh-my-zsh 😃) - -#+end_quote - -Bash-it makes it easy to install plugins, set up aliases for common -commands, and easily change the visual theme of your shell. - -** Installation -To install the framework, simply copy the repository files and use the -=install.sh= script provided. If you want, you can (and should!) inspect -the contents of the installation script before you run it. - -#+begin_src sh -git clone --depth=1 https://github.com/Bash-it/bash-it.git ~/.bash_it -~/.bash_it/install.sh -#+end_src - -If you didn't restart your session after making bash the default, and -are currently working within another shell, be sure to enter a bash -session before using =bash-it=: - -#+begin_src sh -bash -#+end_src - -** Aliases -Bash-it contains a number of aliases for common commands to help improve -efficiency in the terminal. To list all available options, use the -following command: - -#+begin_src sh -bash-it show aliases -#+end_src - -This will provide you a list that looks like the following text block. -Within this screen, you will be able to see all available options and -which ones are currently enabled. - -#+begin_src txt -Alias Enabled?

You can find a -complete list of plugins in the same way as aliases. Simply execute the -following: - -#+begin_src sh -bash-it show plugins -#+end_src - -You will see the following output showing enabled and disabled plugins: - -#+begin_src txt -Plugin Enabled?

For example, I am using -the =zork= theme. - -#+begin_src sh -nano ~/.bashrc -#+end_src - -#+begin_src sh -export BASH_IT_THEME='zork' -#+end_src - -Once you save your changes, you just need to exit your terminal and -create a new one in order to see your changes to the =.bashrc= file. You -can also =source= the file to see changes, but I recommend starting a -completely new shell instead. - -*** ble.sh -One big feature I was missing in Bash that both =zsh= and =fish= have is -an autosuggestion feature. To explain: as you type, an autosuggestion -feature in the shell will offer suggestions in a lighter font color -beyond the characters already typed. Once you see the command you want, -you can click the right arrow and have the shell auto-complete that line -for you. - -Luckily, the [[https://github.com/akinomyoga/ble.sh][Bash Line Editor]] -(ble.sh) exists! This program provides a wonderful autosuggestions -feature perfectly, among other features that I haven't tested yet. - -In order to install ble.sh, execute the following: - -#+begin_src sh -git clone --recursive https://github.com/akinomyoga/ble.sh.git -make -C ble.sh install PREFIX=~/.local -echo 'source ~/.local/share/blesh/ble.sh' >> ~/.bashrc -#+end_src - -Again, exit the terminal and open a new one in order to see the -newly-configured shell. - -* Restart the Session -Finally, as mentioned above, you'll need to restart the session to -ensure that your user is using bash by default. - -You will also need to exit and re-open a shell (e.g., terminal or -terminal tab) any time you make changes to the =.bashrc= file. - -#+begin_src sh -sudo reboot now -#+end_src |
