Long Listing Format

The default output of the ls command shows only the names of the files and directories, which is not very informative.

The -l ( lowercase L) option tells ls to print files in a long listing format.

When the long listing format is used, you can see the following file information:

Total: show total size of the folder.
File type: First field in the output is file type. …
Owner: This field provide info about the creator of the file.
Group: This filed provide info about who all can access the file.
File size: This field provide info about the file size.

What does ls -l*.c do?

The ‘*’ aka wildcard expansion is a way of telling the Linux operating system to find ALL of a certain criteria. Very rarely does a programmer ask to see ALL without defining something specific so instead it is often paired with a file extension such as .jpg (the file extension for pictures) or .js (Javascript files).

If a programmer was to type ls -l*.c the computer would interpret this as find all files in the current directory in the form of long format that have a .c (C programming language) file extension.

In conclusion there are so many commands that you can use to solve problem with Linux and other operating systems.
