This will display a list of all the files and directories in the current directory. The
ls command also has many options that can be used to customize the output. Some of the most useful options include:
-l: This option displays the files and directories in a long format, which includes additional information such as the permissions, owner, group, size, and last modification time.
-a: This option includes hidden files and directories in the output. In Linux, hidden files and directories are those that have a name that begins with a dot (
-h: This option displays the sizes of the files and directories in a human-readable format, rather than in bytes.
-r: This option reverses the order of the files and directories in the output.
To use these options, simply include them as arguments to the
ls command, like this:
$ ls -l
$ ls -a
$ ls -h
$ ls -r
You can also combine multiple options by grouping them together after a single dash, like this:
$ ls -al
This will display the files and directories in a long format and include hidden files and directories in the output.
You can also use the
ls command to list the contents of a specific directory by specifying the path to the directory as an argument, like this:
$ ls /path/to/directory
For example, to list the contents of the
/usr/local/bin directory, you can use the following command:
$ ls /usr/local/bin
Here are some examples of using the
ls command with various options and arguments:
To list the contents of the current directory in a long format, including hidden files and directories, use the following command:
$ ls -al
To list the contents of the
/usr/local/bin directory in reverse order and display the sizes of the files and directories in a human-readable format, use the following command:
$ ls -hr /usr/local/bin

ls command has been helpful!
