RSS Installing htop on Centos

This is htop, an interactive process viewer for Linux. It is a text-mode application (for console or X terminals) and requires ncurses

Comparison between htop and top

• In ‘htop’ you can scroll the list vertically and horizontally to see all processes and complete command lines.
• In ‘top’ you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).
• ‘htop’ starts faster (‘top’ seems to collect data for a while before displaying anything).
• In ‘htop’ you don’t need to type the process number to kill a process, in ‘top’ you do.
• In ‘htop’ you don’t need to type the process number or the priority value to renice a process, in ‘top’ you do.
• ‘htop’ supports mouse operation, ‘top’ doesn’t
• ‘top’ is older, hence, more used and tested.
