Operating Systems OS X (Apple) Can I erase and start my mac with unix command Post 302531929 by ccff22290 on Saturday 18th of June 2011 04:25:54 PM

Can I erase and start my mac with unix command

I made a tragic error and erased the extensions manager from my IMac. Now, I can't get the computer to boot up. It just stays on the gray screen. I've tried using the open apple+s method, which brings up the command console (not sure if I've got the lingo down right), and I've tried everything, but nothing works. I need to be able to reset the system so I can go in and reinstall the os (os X Leopard). Any advice here? I'm like a blind person wandering the streets of NY in search of a needle here.

Thanks in advance

quotacheck(8)						      System Manager's Manual						     quotacheck(8)

Name
       quotacheck - file system quota consistency checker

Syntax
       /etc/quotacheck [ -v ] [ -f ] filesystem ...
       /etc/quotacheck [ -v ] -a

Description
       The  command examines each file system, builds a table of current disc usage, and compares this table against that stored in the disc quota
       file for the file system.  If detects any inconsistencies, it updates both the quota file and the current system copies	of  the  incorrect
       quotas.	Inconsistencies occur only if an active file system is checked.

       Normally,  returns a warning if it cannot find a valid quota file.  If you use the option, creates a quota file automatically and then per-
       forms its normal functions.

       If you use the flag in place of any file system name, checks all the file systems listed in to be read-write with disc quotas.

       Normally reports only modified quotas. If the option is supplied, will indicate the calculated disc quotas for each user  on  a	particular
       file system.

       The  command  expects each file system to be checked to have a quota file named in the root directory.  If none is present, will ignore the
       file system.

       The command is normally run at boot time from the file, before enabling disc quotas with For further information, see

       The command accesses the raw device in calculating the actual disc usage for each user.	Thus, the file systems checked should be quiescent
       while is running.

Files
       Default file systems
