Kernel Modules: The Most Depended-On

MediumLinux+ Exam Prep10-15 min

The brief

You're auditing loaded kernel modules. A capture of lsmod is at /root/sys/lsmod.txt (it differs per session). Its third column, 'Used by', counts how many other modules depend on each one. Identify the module that the MOST other modules depend on (highest Used-by count — not the largest Size) and record its name to /root/answers/module.txt.

sort -k3 -rn /root/sys/lsmod.txt

What you'll do

Record the most depended-on module to /root/answers/module.txt
