#### Manual inspection
|
||||
|
||||
It's a good idea to inspect the install script from projects you don't yet know. You can do
|
||||
that by downloading the install script first, looking through it so everything looks normal,
|
||||
then running it:
|
||||
|
||||
```shell
|
||||
curl -Lo install.sh https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh
|

sh install.sh

### Advanced Installation
|
||||
|
||||
Some users may want to change the default path, or manually install Oh My Zsh.
|
||||
Some users may want to manually install Oh My Zsh, or change the default path or other settings that
|
||||
the installer accepts (these settings are also documented at the top of the install script).
|
||||
|
||||
#### Custom Directory
|
||||
|
||||
The default location is `~/.oh-my-zsh` (hidden in your home directory)
|
||||
|
||||
If you'd like to change the install directory with the `ZSH` environment variable, either by running `export ZSH=/your/path` before installing, or by setting it before the end of the install pipeline like this:
|
||||
If you'd like to change the install directory with the `ZSH` environment variable, either by running
|
||||
`export ZSH=/your/path` before installing, or by setting it before the end of the install pipeline
|
||||
like this:
|
||||
|
||||
```shell
|
||||
export ZSH="$HOME/.dotfiles/oh-my-zsh"; sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
|
||||
ZSH="$HOME/.dotfiles/oh-my-zsh" sh install.sh
|
||||
```
|
||||
|
||||
#### Unattended install
|
||||
|
||||
If you're running the Oh My Zsh install script as part of an automated install, you can pass the
|
||||
flag `--unattended` to the `install.sh` script. This will have the effect of not trying to change
|
||||
the default shell, and also won't run `zsh` when the installation has finished.
|
||||
|
||||
```shell
|
||||
curl -Lo install.sh https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh
|
||||
sh install.sh --unattended
|
||||
```
|
||||
|
||||
#### Installing from a forked repository
|
||||
|
||||
The install script also accepts these variables to allow installation of a different repository:
|
||||
|
||||
- `REPO` (default: `robbyrussell/oh-my-zsh`): this takes the form of `owner/repository`. If you set
|
||||
this variable, the installer will look for a repository at `https://github.com/{owner}/{repository}`.
|
||||
|
||||
- `REMOTE` (default: `https://github.com/${REPO}.git`): this is the full URL of the git repository
|
||||
clone. You can use this setting if you want to install from a fork that is not on GitHub (GitLab,
|
||||
Bitbucket...) or if you want to clone with SSH instead of HTTPS (`git@github.com:user/project.git`).
|
||||
|
||||
_NOTE: it's incompatible with setting the `REPO` variable. This setting will take precedence._
|
||||
|
||||
- `BRANCH` (default: `master`): you can use this setting if you want to change the default branch to be
|
||||
checked out when cloning the repository. This might be useful for testing a Pull Request, or if you
|
||||
want to use a branch other than `master`.
|
||||
|
||||
For example:
|
||||
|
||||
```shell
|
||||
REPO=apjanke/oh-my-zsh BRANCH=edge sh install.sh
|
||||
```

If you have any hiccups installing, here are a few common fixes.

||||
|
||||
* You _might_ need to modify your `PATH` in `~/.zshrc` if you're not able to find some commands after switching to `oh-my-zsh`.
|

* If you installed manually or changed the install location, check the `ZSH` environment variable in `~/.zshrc`.

# BRANCH - branch to check out immediately after install (default: master)

# --skip-chsh: has the same behavior as setting CHSH to 'no'
