ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Description	Syntax
Get the length of a string	`${#VARNAME}`
Get a single character	`${VARNAME[index]}`

Config files

To configure Zsh for your user’s session, you can use the following files:

$ZDOTDIR/.zshenv
$ZDOTDIR/.zprofile
$ZDOTDIR/.zshrc
$ZDOTDIR/.zlogin
$ZDOTDIR/.zlogout

By default, Zsh will try to find the user’s configuration files in the $HOME directory. You can change it by setting the environment variable $ZDOTDIR.

# move to home directory
cd ~

# move the .zsh_history file into another .zsh_history_bad file
mv .zsh_history .zsh_history_bad

# write all printable strings into a new .zsh_history file
strings .zsh_history_bad > .zsh_history
