How to Use Head and Tail Command in Linux
The YouTube video "How to Use Head and Tail Command in Linux" teaches viewers how to use the head and tail commands to view specific lines of a file. By using the head command followed by the file name, users can view the first 10 lines of the file. Alternatively, the tail command can be used to view the last 10 lines. The presenter also explains that users have the option to specify a custom number of lines to display by using the "-n" parameter followed by the desired number. For instance, "head -n 3 filename" will display the first three lines, and "tail -n 3 filename" will display the last three lines.
