Config files

Note: You usually need to create these files if they don’t exist on a new setup.

.zshenv | .bashrc and .bash_profile

Summary: Loaded first for all shell instances (login, interactive, scripts). Used for global environment variable settings.

.zprofile | .bash_profile

Summary: Executed only for login shells, after the initial environment setup and before the interactive configuration. Suitable for one-time login commands.

.zshrc | .bashrc

Summary: Main configuration for interactive shells, loaded on each new terminal. Used for prompt, aliases, functions, options, and plugin loading.

.zlogin | .bash_login

Summary: Executed for login shells, after the main interactive configuration. Less common, for actions after the primary login setup.

.zlogout | .bash_logout

Summary: Executed when logging out of a login shell. Used for logout cleanup.

History

See ~/.oh-my-zsh/lib/history.zsh.

## History command configuration
setopt extended_history       # record timestamp of command in HISTFILE
setopt hist_expire_dups_first # delete duplicates first when HISTFILE size exceeds HISTSIZE
setopt hist_ignore_dups       # ignore duplicated commands history list
setopt hist_ignore_space      # ignore commands that start with space
setopt hist_verify            # show command with history expansion to user before running it
setopt share_history          # share command history data

You can override those in your own config.

unsetopt share_history

Warning - the history.sh file gets loaded after your ~/.zshrc file.
