htop [-dChusv]
Options:
-d –delay : Used to show the delay between updates, in tenths of seconds.
-C –no-color –no-colour : Start htop in monochrome mode.
-h –help : Used to display the help message and exit.
-u –user=USERNAME : Used to show only the processes of a given use
-p –pid=PID, PID… : Used to show only the given PIDs.
-s –sort-key COLUMN : Sort by this column (use –sort-key help for a column list).
-v –version : Output version information and exit.
-F --filter=FILTER Show only the commands matching the given filter
-U --no-unicode Do not use unicode but plain ASCII
-H --highlight-changes[=DELAY] Highlight new and old processes
-M --no-mouse Disable the mouse
-t --tree Show the tree view (can be combined with -s)
