Operating Systems Solaris What is the diffe b/w init s and init S Post 302465481 by snchaudhari2 on Friday 22nd of October 2010 01:49:23 PM

init S:

will take you in the system maintenance mode, where you can use fsck on mounted file systems or to repair file systems...


init s

will take you in the single user mode, where you can unmount your whole file system and mount it on /a or /mnt and can make changes to filesystems...you can also use fsck here.

In short,
if you just need to do file system check, you can use "init S". and if you want to modify files, blocks, cylinders, you can use "init s"

Correct me if I am not....
