A. Linux is a unix-like os, as are Solaris, Aix, OSX, BSD etc. Unix is an old os that set a standard for general computing techniques, linux strives towards posix compliance. Not sure what that means, but it sounds good!

POSIX is a standard set by the ISO I believe, kind of like IEEE 1284 or something. It's something that MS steers away from.

SUS (Single Unix Specifications) :
http://en.wikipedia.org/wiki/Single_UNIX_Specification
Quote:
Linus Torvalds designed Linux to be as POSIX conforming as possible. First, this was a lot of guess-work, because he purchased a printout of the standard some time after starting on Linux. He is also said to have based his system call behavior on man pages from other systems.

Most Linux vendors do not go to the expense of certifying a given version of their distribution as meeting the SUS. Furthermore, the content of a typical Linux distribution changes so fast that recertification would be required far more often than would be financially viable.

For Linux systems, several common extensions and complementary de facto standards are provided by the Linux Standard Base.
AIX, HP-UX and Solaris are SUS compliant (http://www.opengroup.org/openbrand/r...r/company.htm). Linux is not, can not and should not. Linux is free to move wherever it has to move. Some linux distributions could be but there isn't and no one seem to care about that.

Dear Friends/Sirs
We r currently using linux as our main OS and our 150 users working on this but many those shutdown the machine incorrectly,than everytime machine waits for only 5 seconds to checking file system and proper bootup next time when they started.Is there any to increase this time so that user can give 'Y' before 5 seconds and system started properly.

Thanks in advance and hoping for the better reply.

Regards

Jimit
