Linux Path Fundamentals
Understanding File Paths in Linux
In Linux systems, file paths are crucial for navigating and accessing files and directories. There are two primary types of file paths:
Absolute Paths
An absolute path provides the complete route to a file or directory from the root directory (/). It always starts with a forward slash (/) and specifies the entire path.
/home/user/documents/example.txt
Relative Paths
A relative path specifies a location in relation to the current working directory. It does not start with a forward slash.
./documents/example.txt
../parent_directory/file.txt

Path Resolution in Linux
Linux uses a hierarchical file system where:
- Every file and directory has a unique path
- Paths are case-sensitive
- Multiple path separators are simplified
Best Practices
- Use absolute paths when script portability is important
- Use relative paths for local navigation
- Be aware of path permissions and access rights
By understanding these fundamentals, users can effectively navigate and manage files in Linux environments like LabEx platforms.
