What is a C file?

What happens when you type ls *.c? A C file is a source code file for a C. The C files can be edited in any basic text editor, but the syntax of the code will be not displayed, as do the other programs, because a compiler is needed. The C programming language was developed in the 60s and 70s by Dennis Ritchie to create utilities for Unix. The C language has also influenced the development of several programming languages ​​such as C ++, Java, Python, among others. When the command ls * .c Shell runs, lists all files with the .c extension corresponding to compile the script in C.

The character (*) means that the file name can be called in any way, the dot (.) means that it is a file with an extension, which in this case is (c) that corresponds to all files created in the programming language C. The character (*) means that the file name can be called in any way, the dot (.) means that it is a file with an extension, which in this case is (c) that corresponds to all files created in the programming language C.

Also remember that in Shell we can see all the files according to the PATH where we are located, besides that we can create an alias to represent our current user in Shell.

And finally, let’s remember that in Shell we can create variables that we can use in our programming codes. We can store these variables either in our local PATH or in the global variables in the main linux PATH. To do this, we execute the following command:

$ export HOLBERTON=”Betty”
