Kernel map (interactive)


This gives the complete overall picture of the kernel map on Linux

Technical (Tracking process)

Let’s assume you have written two script name script1.sh and script2.sh. You can do this
time ./script1.sh
Same thing to script2.sh, and the results will looks as bellow:
real 0m1.005s
user 0m0.000s
sys 0m0.008s
real shows you the execution time script1.sh takes, o minutes 1.005 seconds. user and sys tracks the CPU processing time. From the results, shows us that script1.sh uses 8 milliseconds CPU processing time in kernel mode (sys) and None in user mode.
