Hi Venkat,
Thank you very much for the reply, just got few doubts in the prototype you have attached.
1) In the first line, you have mentioned there is "/bin/uname" what is this exactly for and in place of uname do I need to give the username with which I am connecting to remote server?
2) Also there is "> /dev/null 2>&1;" in the script, is it mandatory to have this line in the script as I don't have permission to that path, including it may fail the script and can I specify any other path instead of it?
Please don't mind if the above questions sound silly, as I am a novice to unix, I find them hard to under stand.
Thanks for your help
Regards.

uname
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 fur-
ther identify the operating system. The machine member contains a standard name that identifies the hardware on which the operating system
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.
