E-learning module "Linux Basics"
Introduction
Everything is a file in Linux:
- Data and directory files (obvious!)
- But also, for example,
- Network connections
- Hardware (/dev directory)
File names can have max. 256 characters (and require no extension for the file type).
Linux is case sensitive; filename is not the same as Filename!
File names can consist of (selection only)
- upper case
- and lower case characters,
- numbers,
- dash, underscore, dot.
Special characters which cannot be part of a file name are (only a selection):
/→ path seperator?→ wildcard for a single character*→ wildcard for multiple characters[ ]→ a character in the brackets can be replaced[A–Z]→ range to be replaced\→ backslash is the escape character for special characters<,>→ redirect in- and output|,||,;,&&→ concatinate commands(,)→ grouping of commands",',`→ quotes
