Creating and organising files

Articles

• Glob patterns and brace expansion — Shell substitutions — * ? [] {} — and how they differ from regular expressions.
• Basic file commands — Navigation and files — ls, cd, cp, mv, rm, cat, less, head, tail, terminal copy-paste.
• ls — list directory contents — The ls command lists files and directories with permissions, owner, size and modification time, hidden ones too.
• mkdir — creating directories — Creating directories: -p (with parents), -m (permissions right away), brace expansion, rmdir.
• cp — copy files and directories — The cp command copies files and directories, with overwrite prompts, preserved permissions and times, recursively.
• mv — move or rename — The mv command renames a file or directory and moves it elsewhere; it silently replaces an existing target.
• rm — remove files and directories — The rm command deletes files and directories at once, with no trash; -i and -I ask first, -r removes a tree.
• Paths — basename, dirname, realpath — Splitting a path into a name and a directory, getting an absolute path; a script's own directory.
