tail: Display the end of a file

The format of the tail command is:

head [ -count ] [ file ]

tail displays the end of the file to standard output. If no file is named, the standard input is used. The output displayed begins at distance + number from the beginning or -number from the end of input. Number is counted in units of lines, blocks or characters, based on the appended option l, b or c. The default unit if none is specified is lines.

cat cli_workshop/data_files/operatingsystemlist

you will see output like this:
