Cut Command in Linux – Extract Fields and Columns from a file ~ Your Own Linux..!

   In some of my recent articles on text processing, I have explained the use of sed command in Linux/Unix. In case of sed command, we provide an input file to the command, it reads the file line-by-line, processes each line and then prints it on the STDOUT. So, in brief, its a row-wise operation. Similar is the case with cut command – there is an input file, there is processing part and the processed output can be displayed on STDOUT or saved in a file. A minor difference between sed and cut is that, cut command processes the file in vertical manner. So, the outcome of the cut command is a single or multiple columns.

10 Practical Examples Of Linux ‘nmap’ Command | Unixmen

Nmap is a tool used for determining the hosts that are running and what services the hosts are running. Nmap can be a valuable diagnostic tool for network administrators while they can be also a potent reconnaissance tool for the Black-hat community (Hackers, Crackers, Script Kiddies, etc). Once the network is charted out using tools like Lan MapShot, the Nmap can be used to determine the type of services and hosts running in the network.

In this article, we will cover some useful practical examples of Linux namp command.
