Finding the PID of a Process Using a Specific Port in Linux

BySumGuy

In Linux, identifying which processes are using specific ports is crucial for managing network services and troubleshooting issues. Tools like `netstat`, `ss`, and `lsof` provide different ways to find the PID of a process bound to a port. `netstat` offers a traditional approach, `ss` delivers faster results with more details, and `lsof` lists extensive information about files opened by processes, including network sockets. Choosing the right tool depends on the user’s specific needs and system configuration.

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.
