The ls command can be used to display hidden files in Ubuntu using the terminal (command line). The ls command has many parameters that you can use to get information about files. The Ls command options “-a” and “-l” can be used with the Ubuntu ls command to display hidden files in Ubuntu using the terminal command line.

The ls program displays information about files (of any type, including directories). File options and arguments can be mixed arbitrarily, as usual. For non-option command line arguments that are directories, by default “ls” lists the contents of directories, rather than recursively, and skips files with names starting with “.” For other non-option arguments, by default “ls” lists only the filename. If no non-option argument is specified, ‘ls’ treats the current directory as if it had been called with one argument, ‘.’.

By default, output is sorted alphabetically according to the current locale setting. (1) If standard output is a terminal, the output is output in columns (sorted vertically) and control characters are output as question marks; otherwise, the output is printed, one on each line, and the control characters are printed as they are.

Because “ls” is such a fundamental program, it has accumulated many variations over the years. These are described in the subsections below; in each section, the options are listed in alphabetical (case-insensitive) order. The subdivision of parameters is not absolute because some parameters affect more than one aspect of ls.

The “ls” command option “-a” will show all files and folders, including hidden ones. It displays a list in “long format” that includes permissions, owner, group, size, last modified date, number of hard links, and the file name described.

You can use the following command parameters:

  1. ‘-a’ or ‘–all’: In directories, do not ignore filenames starting with ‘.’.
  2. “-A” or “- almost all”: In directories, do not ignore all filenames starting with ‘.’; ignore only ‘.’ and ‘..’. The “-all” (“-a”) option overrides this option.
  3. ‘-l’ or ‘–format = long’ or ‘–format = verbose’: Besides the name of each file, output the file type, file mode bits, number of hard links, owner name, group name, size and timestamp (note Note Formatting file timestamps: :), this is usually the modification time. Type question marks for information that cannot be identified. For each directory listed, add the line “total BLOCKS” to the files, where BLOCKS is the total amount of disk space for all files in that directory. The default block size is currently 1024 bytes, but this can be changed (Note Block size: :). The computed BLOCKS count each hard link separately; perhaps this is a flaw.

Note that there is a difference between the -a and -A options. The -a option displays hidden files and directories with the current directory (.) And parent directory (..), where the -A ls command options do not show it.
