htop Command Examples in Linux¶

Introduction¶

These examples show practical ways to use htop on a Linux terminal. Each example is written so you can adapt it for administration or troubleshooting.

Example 1: Basic Usage¶

htop

This is the simplest form of the command and is a good starting point before adding options.

Example 2: Common Admin Task¶

htop -u apache

This example reflects a common task on RHEL, Rocky Linux, AlmaLinux, or similar systems.

Example 3: Useful Option¶

htop -p 1234

This option helps narrow the result, change behavior, or handle a more realistic target.

Example 4: Real-World Scenario¶

htop --tree

Use this pattern when the task moves beyond a single basic command.

Example 5: Verification¶

htop --version

Example output:

htop 3.2.2

Common Mistakes¶

• Assuming htop exists on minimal servers.
• Killing processes from the interface before checking what owns them.
• Forgetting that htop is interactive and less suitable for non-interactive scripts.

Quick Reference¶
