# Switching Languages on Monsoon (Mandarin)

Below you will find instructions for what is needed for each student to perform to enable Mandarin support in SSH sessions and OnDemand.

> [!NOTE]
>
> This localization support depends on what has been provided through each individual piece of software. The changes performed from the instructions below will add **partial** support for Mandarin.

## Changing Terminal Language

### Enabling Mandarin for the Terminal

To enable Mandarin in a terminal on Monsoon, all you need to do is copy the file `/common/conf/mandarin_ssh` to your home directory under the name `.i18n`. To do this, open a terminal connected to Monsoon and run the following command:

```bash
cp /common/conf/mandarin_ssh ~/.i18n
```

Once you have run this command, **re-login to Monsoon** to see the changes.

### Verify that Mandarin is Enabled

Once you have started a new terminal session on Monsoon, you can use the `locale` command to see your current language.

```bash
[abc123@wind]:~$ locale
LANG=zh_CN.utf8
LC_CTYPE="zh_CN.utf8"
LC_NUMERIC="zh_CN.utf8"
LC_TIME="zh_CN.utf8"
LC_COLLATE="zh_CN.utf8"
LC_MONETARY="zh_CN.utf8"
LC_MESSAGES=zh_CN.utf8
LC_PAPER="zh_CN.utf8"
LC_NAME="zh_CN.utf8"
LC_ADDRESS="zh_CN.utf8"
LC_TELEPHONE="zh_CN.utf8"
LC_MEASUREMENT="zh_CN.utf8"
LC_IDENTIFICATION="zh_CN.utf8"
LC_ALL=
```

If you see `zh_CN`, then Mandarin support is enabled.

### Disabling Mandarin for the Terminal

To disable Mandarin in a terminal on Monsoon, you can remove the `.i18n` file by opening a terminal connected to Monsoon and running the following command:

```bash
rm ~/.18n
```

Once you have run this command, **re-login to Monsoon** to see the changes.

## Changing OnDemand Language

Mandarin on OnDemand is triggered when the file `~/.config/ondemand/chinese` exists. The contents of the file do not matter, but as long as the exact file and exact parent directories exist, OnDemand will change the display language to Chinese.

### Enabling Chinese for OnDemand

To create the necessary file that enables Chinese for OnDemand, follow these steps:

1. Open a terminal and connect to Monsoon.
2. Run the following commands:

```bash
mkdir -p ~/.config/ondemand
touch ~/.config/ondemand/chinese
```

Once you have run this command, **re-login to Monsoon** to see the changes.

### Disabling Chinese for OnDemand

To remove the file that enables Chinese for OnDemand, open a terminal connected to Monsoon and run the following command:

```bash
rm ~/.config/ondemand/chinese
```

Once you have run this command, **re-login to Monsoon** to see the changes.
