"uname -a" is the right linux operating command, but it is not too helpful in determining which Linux Distro you have. It should at least inform you that you are running Linux and not HP-UX, FreeBSD, SunOS, etc.
As for which distro, Linux does not yet have a great way to do this, but it is moving towards a way. See:
http://linuxmafia.com/faq/Admin/release-files.html for a good write-up on the current state of affairs.

uname
UNAME(1) BSD General Commands Manual UNAME(1)
NAME
uname -- display information about the system
SYNOPSIS
uname [-aiKmnoprsUv]
DESCRIPTION
The uname command writes the name of the operating system implementation to standard output. When options are specified, strings represent-
ing one or more system characteristics are written to standard output.
The options are as follows:
-a Behave as though the options -m, -n, -r, -s, and -v were specified.
-i Write the kernel ident to standard output.
-K Write the FreeBSD version of the kernel.
-m Write the type of the current hardware platform to standard output.
-n Write the name of the system to standard output.
-o This is a synonym for the -s option, for compatibility with other systems.
-p Write the type of the machine processor architecture to standard output.
-r Write the current release level of the operating system to standard output.
-s Write the name of the operating system implementation to standard output.
-U Write the FreeBSD version of the user environment.
-v Write the version level of this release of the operating system to standard output.
If the -a flag is specified, or multiple flags are specified, all output is written on a single line, separated by spaces.
The -K and -U flags are intended to be used for fine grain differentiation of incremental FreeBSD development and user visible changes.
ENVIRONMENT
An environment variable composed of the string UNAME_ followed by any flag to the uname utility (except for -a) will allow the corresponding
data to be set to the contents of the environment variable.
EXIT STATUS
The uname utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
feature_present(3), getosreldate(3), sysctl(3), uname(3), sysctl(8)
STANDARDS
The uname command is expected to conform to the IEEE Std 1003.2 (``POSIX.2'') specification.
HISTORY
The uname command appeared in PWB UNIX.
The -K and -U extension flags appeared in FreeBSD 10.0.
