Give three examples of hidden files shown in the output of ls -la above.
Work with hidden files in Linux. a. In Linux, files with names that begin with a ‘.’ (single dot) are not shown by default. While dot-files have nothing else special about them, they are called hidden files because of this feature. Examples of hidden files are .file5, .file6, .file7. b. Use ls -l to display the files stored in the analyst home directory.
[analyst@secOps ~]$ ls –lc. Use the ls -la command to display all files in the home directory of analyst, including the hidden files.
[analyst@secOps ~]$ ls –lad. Type the man ls command at the prompt to learn more about the ls command.
[analyst@secOps ~]$ man lse. Use the down arrow key (one line at a time) or the space bar (one page at a time) to scroll down the page and locate the -a used above and read its description to familiarize yourself with the ls -a command.
