fsck command

i saw this in a post however when you hold down the command and S keys at startup it goes to a black screen lists a bunch of what look like unix commands top to bottom but never gets to a command line where i can type these commands?
Run fsck.

1. Reboot/Startup holding your Command-S key down.
2. At the command line type the following and hit 'Return.'

/sbin/fsck -fy

3. If it finds a problem and repairs it, immediately run fsck again until the drive checks OK.

4. After it has check/repaired your disk, type 'reboot' and hit 'Return' again.

If everything checks OK, try running the 10.5.7 combo updater again.

Why do you need to do this? You can repair the drive without having to boot into single-user mode by using Disk Utility:

Repairing the Hard Drive and Permissions

Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.

If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
