Enable `zsh` in Manjaro

The output of `neofetch` on my ROG laptop

I have been a typical bash user for almost 30 years. Recently I became curious about zsh and decided to give a try on my Manjaro Linux. The most Linux distributions have zsh installed by default. Here, I’ll directly introduce how to get the fancy plugins setup, with ohmyzsh > https://github.com/ohmyzsh/ohmyzsh

Install through command line

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

After the install, your default SHELL should switch to zsh. You can verify it

echo $0 ps -p $$ lsof -p $$

Edit `~/.zshrc`

You can edit theme > https://github.com/ohmyzsh/ohmyzsh/wiki/Themes or configure plugins, like mine

plugins=(
 git
 history-substring-search
 colored-man-pages
 zsh-autosuggestions
 zsh-syntax-highlighting
)

After saving the edit, you’d install the plugins on operating system. Here’s the command on Manjaro, for example

 sudo pacman -S zsh-autosuggestions zsh-syntax-highlighting

Source your `~/.zshrc`

source ~/.zshrc

Check `bindkey`

bindkey | fgrep history
"^[OA" history-substring-search-up
"^[OB" history-substring-search-down
"^[[5~" up-line-or-history
"^[[6~" down-line-or-history
"^[[A" up-line-or-history
"^[[B" down-line-or-history

If you have `conda` installed, you’d run `init`

cd ~/miniconda3/bin
./conda init zsh

It will update ~/.zshrc

If you want to search in `vi` mode

I’m a proud and traditional vim user and wish to search in vi mode in command line. You can add the following into ~/.zshrc

bindkey -M vicmd '/' history-incremental-search-backward

If you want to go back to default setting of `zsh`

Execute the following command

/etc/skel/.zshrc
