After installing some RAM my macbook pro would not start, diskutil showed HDD failure.
Booting in single user mode and running fsck several times to repair the disk lead to a running system.
But now, some of the Unix binaries (as well as some data) - like rm and less - are missing.
I have copied them from another mac.
The question is: if I reinstall OSX will it also install those and any other that might be missing?
