I want to find out what is Linux using to control my hardware. I guess modules and drivers and maybe they are the same.

I got this answer : How do I find out which driver a piece of hardware is using?

And there's a way to list the drivers but I also want to add an identifier to each list item.

If I run this command the this is what happens :

sudo lshw | grep -Eo 'driver=[^ ]+' | sort -u | cut -d\= -f2

agpgart-intel

ahci

ath9k

atl1c

ehci-pci

hub

i915

intel

lpc_ich

mei_me

pcieport

snd_hda_intel

tun

usb-storage

uvcvideo

  • Do you know what sudo lshw | grep -Eo 'driver=[^ ]+' | sort -u | cut -d\= -f2 does? sudo lshw prints all information about your hardware; the rest of the command filters and sorts the output such that in the end you get a list of drivers in use. If you want all information, just run sudo lshw. – danzel Mar 02 '16 at 14:35
  • If you're fine with listing only PCI devices, you could parse lspci -k. – kos Mar 02 '16 at 14:39
  • Please edit your question and explain what exactly you want to achieve ("identifier"?). – danzel Mar 02 '16 at 15:00
  • Answer posted, please let me know what you think. Also, in the linux world, drivers = modules, they're the same. – Sergiy Kolodyazhnyy Mar 02 '16 at 15:15

If you are concerned with only filtering output of lshw to show device and its corresponding driver, you can use the lshw and awk combination bellow:

sudo lshw | awk '/product:/{  if(length(PROD) > 0){PROD=""};  for(i=1;i<=NF;i++) PROD=PROD" "$i  } /driver=/{  for(j=1;j<=NF;j++){ if($j~/driver=/) DRIVER=$j   };print "---",PROD,DRIVER; PROD=""}'

Basic idea here is that we find lines that have "product: . . . " in them and store into PROD. Because some devices don't list drivers, we could have repeatedly appended line after line to PROD variable, so in the beginning we check length of the PROD string. Another matching that is going on, is for the lines containing the driver= part. Once we have that, we print both the product and the driver information.

Bellow is the command put together into a script, and sample output:

$ cat ./dev-drivers.sh                                                                                            
#!/bin/bash

sudo lshw | awk '/product:/{  if(length(PROD) > 0){PROD=""};\
            for(i=1;i<=NF;i++) PROD=PROD" "$i  }\
             /driver=/{  for(j=1;j<=NF;j++){ if($j~/driver=/) DRIVER=$j   };\
             print "---",PROD,DRIVER; PROD=""}' 

$ ./dev-drivers.sh

  • I want to add the description will this work ?

    sudo lshw | awk '/product:/ {if(length(PROD) > 0){PROD=""}; \for(i=1;i<=NF;i++) PROD=PROD" "$i} /driver=/ {for(j=1;j<=NF;j++){ if($j~/driver=/) DRIVER=$j}; /description:/ {if(length(DESC) > 0){DESC=""}; \for(i=1;i<=NF;i++) DESC=DESC" "$i} \print "---",PROD, DESC,DRIVER; PROD=""}'
