What is the primary purpose of the 'cat' command in a Linux environment?
To compare the contents of files line by line
To edit the contents of a text file interactively
To read and display the content of files on standard output
To display the first few lines of a file
The 'cat' command is used to read and display the content of files on standard output. By mastering its usage, users can view the contents of a file or concatenate multiple files easily. The incorrect options relate to file editing, file comparison, and reading the beginning of files, which are tasks associated with other commands ('nano', 'diff', and 'head', respectively).
