LPIC-1 System Architecture Practice Question
Which command can be used to check whether a specific kernel module is currently loaded?
⚠ Common exam trap
A common mix-up: candidates confuse `modinfo` (which shows module information from disk) with `lsmod` (which shows runtime load status), leading them to incorrectly select option A.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
lsmod | grep <module>
`lsmod` lists all currently loaded kernel modules by reading the `/proc/modules` file, and piping its output through `grep` filters for the specific module name. This directly shows whether the module is loaded in the running kernel, which is the exact requirement of the question.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
modinfo <module>
Why it's wrong here
modinfo displays module information, not load status.
- ✓
lsmod | grep <module>
Why this is correct
lsmod lists loaded modules; grep filters.
- ✗
depmod -a
Why it's wrong here
depmod generates dependency files, does not show loaded modules.
- ✗
insmod <module>
Why it's wrong here
insmod loads a module, does not check.
