# This script should be run via curl:
|
|
# sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
|
|
# or wget:
|
|
# sh -c "$(wget -qO- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
|
|
#
|
|
# As an alternative, you can first download the install script and run it afterwards:
|
|
# wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
|
|
# sh install.sh
|
|
#
|
|
# You can tweak the install behavior by setting variables when running the script. For
|
|
# example, to change the path to the Oh My Zsh repository:
|
|
# ZSH=~/.zsh sh install.sh
|
|
#
|
|
# Respects the following environment variables:
|
|
# ZSH - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)
|
|
# REPO - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)
|
|
# REMOTE - full remote URL of the git repo to install (default: GitHub via HTTPS)
|
|
# BRANCH - branch to check out immediately after install (default: master)
|
|
#
|
|
# Other options:
|
|
# CHSH - 'no' means the installer will not change the default shell (default: yes)
|
|
# RUNZSH - 'no' means the installer will not run zsh after the install (default: yes)
|
|
#
|
|
# You can also pass some arguments to the install script to set some these options:
|
|
# --skip-chsh: has the same behavior as setting CHSH to 'no'
|
|
# --unattended: sets both CHSH and RUNZSH to 'no'
|
|
# For example:
|
|
# sh install.sh --unattended
|
|
#
|
|
set -e
