The version of cut bundled in GNU coreutils was written by David M. Ihnat, David MacKenzie, and Jim Meyering. [5] The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities. [6] The cut command has also been ported to the IBM i operating system. [7]

The GNU Core Utilities or coreutils is a package of GNU software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems.
Here the first sort is done using column 2. -k2,2n specifies sorting on the key starting and ending with column 2, and sorting numerically. If -k2 is used instead, the sort key would begin at column 2 and extend to the end of the line, spanning all the fields in between.
The Unix program which spawns all other processes. As of 2016, for major Linux distributions, it has been replaced by systemd.

The first two columns contain lines unique to the first and second file, respectively. The last column contains lines common to both. This functionally is similar to diff. Columns are typically distinguished with the <tab> character. If the input files contain lines beginning with the separator character, the output columns can become ambiguous.
The first column is the count of newlines, meaning that the text file foo has 40 newlines while bar has 2294 newlines- resulting in a total of 2334 newlines. The second column indicates the number of words in each text file showing that there are 149 words in foo and 16638 words in bar – giving a total of 16787 words.
