Believe it or not, nslookup.
nslookup
dig
Here is what I was able to do on our local system: $ uname -a SunOS <uname -n> 5.9 Generic_122300-25 sun4u sparc SUNW,Sun-Fire-15000 $ /usr/sbin/nslookup <IP-ADDRESS> *** Can't find server name for address <SERVER_IP1>: Server failed Server: <F.Q.D.N of SERVER_IP0> Address: <SERVER_IP0> nslookup is a standard TCP/IP utility, which exists in both Windows and Unix. You could also use 'dig' as a replacement in Unix.
In Windows and Unix-based and Unix-like systems, the command is mkdir (however in Windows a shortcut md can be used as well).
UNIX is a command-based OS. In contrast, Windows is a menu-based OS.
The nslookup command is a user interface to the DNS service, and provides name resolution lookup (among other things). It can also be used to debug problems with DNS resolution and the DNS configuration itself, return zone information, etc.
A Unix shell can be obtained in Cygwin, a Unix compatibility layer used to compile Unix programs and run them on Windows. Microsoft also makes a shell known as "Windows PowerShell" which incorporates more Unix-like features than the standard command prompt.
Because Linux was modeled after Unix, and designed to be a suitable free replacement. Windows is targeted at a slightly different market, and was primarily designed to be operated using a GUI, not the command line.
You look at the file. A program such as Windows Explorer - or the equivalent in other operating systems - can tell you the size. Also, a command such as "dir" (in Windows), or "ls" (in Linux or Unix).
The 'type' command does approximately (but not exactly) the same thing as the 'cat' command.
For Unix/Linux, use the command 'cd /' For Windows, you can also use the same command or 'cd \'
Such short abbreviations normally mean several things. One meaning of "ls" is the command used in UNIX and Linux to show a list of files. This is basically the equivalent of the DOS/windows "dir" command.
