My iMac wont update and is missing data.

My imac is not updateing and trying everything doesnt help. I reasently installed Paralles and had to contact help line for them to assist in loading it. They told me i was missing important data namely

grep

whoami

chown

stat

Which means nothing to me. I have Time Machine and my data is backed up.

Should I eraze the imac and reload Mountain Lion.

Any help would be great as iTunes is out of date and I cant install any Apple updates.

iMac, OS X Mountain Lion (10.8.3)

Triple-click anywhere in the line below on this page to select it:

/usr/bin/grep

Right-click or control-click the highlighted line and select

Services ▹ Show Info

from the contextual menu.* An Info dialog should open. Does the dialog show "You can only read" in the Sharing & Permissions section?

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it ( command-V). Select the line you just pasted and continue as above.

You might be able to fix the system corruption by repairing permissions in Disk Utility. Otherwise, back up all data and then reinstall OS X.

All they can do is reinstall the OS. You can do that yourself.

If you don't already have a current backup, back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you may need the Apple ID and password you used to upgrade.

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.
