Process States in Linux Explained

Ever wondered what all those process states like "sleeping", "zombie", or "uninterruptible" actually mean in Linux? In this video, I break down the most common Linux process states, explain what each one means, how to identify them using tools like ps and top, and when to take action. This is essential knowledge for anyone working with servers, performance tuning, or troubleshooting production environments. Watch now to get a deeper understanding of how Linux handles processes - from R to Z. Common Linux Process States and How to Identify Them Running (R) – Actively using the CPU or ready to run. ps -eo pid,stat,comm | grep ' R' Use top to view in real time. Sleeping (S) – Waiting for an event like I/O. ps -eo pid,stat,comm | grep ' S' Most processes spend time in this state. Uninterruptible Sleep (D) – Waiting for I/O; can't be killed easily. ps -eo pid,stat,comm | grep ' D' Often points to disk or hardware latency. Stopped (T) – Process is paused (e.g., with Ctrl+Z). ps -eo pid,stat,comm | grep ' T' Resume with fg or kill if needed. Zombie (Z) – Finished process waiting for its parent to collect exit status. ps -eo pid,ppid,stat,comm | grep ' Z' Doesn't use CPU/memory but clutters process table. Idle (I) – Kernel thread waiting for CPU. ps -eo pid,stat,comm | grep ' I' Usually seen in multi-core systems. Traced/Stopped (t) – Process being debugged. ps -eo pid,stat,comm | grep ' t' Normal during development with gdb. Dead (X) – Terminated process, rarely seen. ps -eo pid,stat,comm | grep ' X' Usually gone quickly; indicates kernel cleanup. Orphan – Child process without a parent (adopted by PID 1). ps -eo pid,ppid,comm | awk '$2==1' Can result from mismanaged parent processes. 00:00 Introduction 00:28 Please support this channel via Like and Subscribe 00:46 Running Process State 01:22 Sleeping Process State 01:46 Uninterruptible Sleep Process State 02:16 Stopped Process State 02:38 Zombie Process State 03:02 Orphan Process State 03:28 Idle Process State 03:46 Waiting Process State 04:05 Dead Process State 04:19 Traced Process State 04:33 Paging Process State 04:56 Unknown Process State 05:18 High Priority Process 05:38 Low Priority Process 05:48 Multithreading Process 05:58 Summary #linux #linuxtutorials #linuxtutorial #linuxtutorialforbeginners #linuxskills #linuxadministration #process #processstate #linuxprocessstate #itcareer #realtech #technology #cloud #linuxterminal
