uname -a output
07-19-2011
) This particular distribution seems to be Red Hat Enterprise Linux 5 (.el5 in the output of uname -a). As for the books, there are plenty of various books taking the subject of Linux administration. I would suggest first going for some basic book covering Linux fundamentals, like managing files, working with the shell etc. After that you can move to something more specific, maybe something about administering RHEL5, so you can practice on your server. It is important to know that Linux comes in many different distributions, so books covering one might be not very accurate for another.|

uname(2) System Calls uname(2) NAME
uname - get name of current operating system SYNOPSIS
#include <sys/utsname.h> int uname(struct utsname *name); DESCRIPTION
The uname() function stores information identifying the current operating system in the structure pointed to by name. The uname() function uses the utsname structure, defined in <sys/utsname.h>, whose members include: char sysname[SYS_NMLN]; char nodename[SYS_NMLN]; char release[SYS_NMLN]; char version[SYS_NMLN]; char machine[SYS_NMLN]; The uname() function returns a null-terminated character string naming the current operating system in the character array sysname. Simi- larly, the nodename member contains the name by which the system is known on a communications network. The release and version members further identify the operating system. The machine member contains a standard name that identifies the hardware on which the operating sys- tem is running. RETURN VALUES
Upon successful completion, a non-negative value is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The uname() function will fail if: EFAULT The name argument points to an illegal address. ATTRIBUTES
