#!/bin/sh |

# |

|
# This script should be run via curl: |
||||||
|
# sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)" |
||||||
|
# or wget: |
||||||
|
# sh -c "$(wget -qO- https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)" |
||||||
|
# |
||||||
|
# As an alternative, you can first download the install script and run it afterwards: |
||||||
|
# wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/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: robbyrussell/oh-my-zsh) |
||||||
|
# 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 |
||||||
|
# |
||||||
|
