How to show only user processes in htop?
To show only user processes in htop, you can press the u key in htop. This will bring up a menu that allows you to filter the process list by user. From the user filter menu, you can select the specific user whose processes you want to view. Once you have selected the user, htop will only display the processes owned by that user.
Alternatively, you can start htop with the -u option followed by the username whose processes you want to view. For example, to view only the processes owned by the user “jdoe”, you can use the following command:
htop -u jdoe
This will start htop and display only the processes owned by the user “jdoe”.
