The Line Command!
Many operating systems provide both a command line and a GUI interface. Windows, for instance, is obviously a GUI, however cmd.exe provides access to the underlying command line interface.

The command used to compare files in Unix-like operating systems is diff. This command analyzes two files line by line and displays the differences between them. For example, running diff file1.txt file2.txt will show any lines that differ between the two files. Additionally, the cmp command can be used for a byte-by-byte comparison, while comm can be used to compare sorted files.

Compiling and running are two completely different procedures. To compile a C program you need a C compiler and linker (two separate programs). Once the source code has been compiled to object files you then need to link those files to create an executable. Once you have an executable you can run it. There's nothing particularly special about compiling from the command line as opposed to compiling within an integrated development environment (IDE). They both do exactly the same thing. However, an IDE is easier because it not only helps you easily organise your project files, it can build (compile and link) and execute the program with a single command. The end result is exactly the same as you would get by manually compiling, linking and executing from the command line. Command lines include a bewildering array of options and switches (parameters). To make sense of them, it is best to use the IDE and examine the command line that it generates for you, changing compiler and linker options to see what effect that has on the command line. Once the IDE command line settings are exactly the way you want them you can copy/paste those command lines into a command file (*.cmd) or a batch file (*.bat) which you can easily invoke from the command line.
