Filesystem Navigation

Core Idea

Filesystem navigation is the skill of knowing where your shell is and choosing paths deliberately.

The filesystem is a tree of directories and files. Your shell always has one current working directory.

Core Commands

• pwd: print where you are.
• ls: list nearby entries.
• cd: change directory.
• find: search a tree by rules.

Path Vocabulary

• /: root of the filesystem.
• ~: your home directory.
• .: current directory.
• ..: parent directory.
• Absolute path: starts with /.
• Relative path: starts from the current directory.

Lost Pattern

pwd
ls -la
cd ~

Return home, then navigate again deliberately.

Docs Pointers

• Read path, filesystem, file, directory, permissions, and number bases.
• Read pwd, ls, cd, and find.
