To repair a file system in Unix or Linux, you would use the `fsck` command. Here are the steps:

1. First, you need to unmount the file system using the `umount` command. For example, if you want to unmount a file system mounted at /dev/sda2, you would use the following command: `umount /dev/sda2`.

2. Once the file system is unmounted, you can check and repair it using the `fsck` command. For example: `fsck /dev/sda2`. This command will check the file system and fix any errors it finds.

3. If you want `fsck` to fix the errors without asking for your confirmation each time, you can use the `-y` option: `fsck -y /dev/sda2`.

4. After the `fsck` command completes, you can remount the file system using the `mount` command: `mount /dev/sda2`.

Please note that you should replace `/dev/sda2` with the actual path of your file system. Also, you should have root permissions to execute these commands.
