Linux CLI SysAdmin Tools.
Here is just a really short post regarding a collection of CLI SysAdmin tools.
These tools definitely warrant a page in their own right, but I just don’t have the time at the moment.
(And I just wanted to get them down before I forgot them)
I will be expanding this topic at some point (probably in a separate page), but until then, this will have to do!
top
top
Shows system processes in real-time
Displays a dynamic list of processes which (by default) updates every few seconds, and
Focuses on the most CPU-intensive processes
Top enables several commonly used ‘hot keys’ which serve various handy purposes, some of these are:
q – quits the application
z – toggles colour/monochrome
t – toggles summary info
m – toggles memory info
space – refresh display
A – toggles display by categorising processes into groups based on various system resources
f – enters an interactive configuration menu for ‘top’ field management (ESC to return to top display)
r – allows ‘renice’ command to be applied to a particular process via its PID
k – allows ‘kill’ command to be applied to a particular process via its PID
w
