How To Check Patch In Solaris

I am a new Linux system user. How do I check os version in linux command line?

1) Need to take the backup filesystem through ufsdump or, need to remove one of the root mirror from the server. 2) Need to check the current patch version on the server. # uname -a (For kernel patch). That will download the Linux source and patch it to be exactly the same state as the distribution used when they compiled it. In the linux-x.y.z directory are the file(s) mentioned in the patch. Just look at the line numbers and make sure that the lines with minus signs aren't there and the ones with plus signs are. More detailed answer.

Linux is a free and open source operating system. There are many variants of Linux out there. They are typically called Linux distribution. Suse, OpenSUSE, Debian, Ubuntu, CentOS, Arch, Fedora, RHEL all are common Linux distribution names. Knowing your os version and name can be very useful for security patches.
