This article explores the differences and similarities between `nohup`, `disown`, and the `&` operator in Linux, essential tools for managing background processes. `nohup` runs commands that ignore hangup signals, `disown` removes jobs from the shell’s job table, and `&` places commands in the background. Understanding these commands enhances process management efficiency, ensuring tasks continue running smoothly even after logging out, making them invaluable for system administrators managing long-running or continuous processes on Linux systems.

The `lost+found` directory in Linux is crucial for maintaining file system integrity, housing orphaned files during system recovery. Created by `fsck`, it stores files with inconsistencies found during checks. Regularly running `fsck`, especially after crashes, helps prevent data loss. Files in `lost+found` should be inspected before deletion to ensure they are not needed, maintaining strict access permissions to safeguard their contents. This directory should not be used for regular data storage.
