Enlisting kernel modules by Name,Description and Depends

I was wondering how to get a glimpse of all kernel module at once with specific information I need.
I know how to use modinfo ,so thought to implement within a small AWK script which will fetch me the required info.

So just wrote a one liner for that like this:

awk ‘{print $1}’ “/proc/modules” | xargs modinfo | awk /^(filename|desc|depends)/’

That’s all I have done.I put it in a file and give it a execution permission.Once you run it you get the info like below,which is very useful:

    >Thanks. I found this useful, trying to suss out which LKM's are needed for a VM. Bluetooth…no.There is a typo in your line above. Missing single quote. Here is the line that worked for me:awk '{print $1}' "/proc/modules" | xargs modinfo | awk '/^(filename|desc|depends)/'Thanks for saving me head scratching time.CheersBilly BakerSDLC Sysadmin
