Hi,
I have problem with parameter configuration.
My question is after the configuration, how to check if successfully change the value or not?

I saw someone has the same question, and followed his steps.
Original thread:

Which macL mentioned that:

I use the following command:

dmesg -n 8
modprobe igb InterruptThrottleRate=0
dmesg

Though the dmesg didn't show any message related to what macL saw.
Is there any step wrong or missing during the command?

try this:

#!/bin/bash
# parm.shl  display kernel module parameters
# usage ./parm.shl [module name]

# set module or modules to display
default=' '  # display all modules
[ $# -eq 1 ] && default="$1"  # display one module

# get a list of modules
fgrep "$default" /proc/modules | awk '{print $1}' > mod.lis

# process list of modules
while read module
do 
  printf "%s %s\n" "Module:" "$module"
  dir="/sys/module/$module/parameters"
  
  # is there a parameter directory
  [ ! -d "dir" ] && printf "\t%s\n" 'No parameters' && continue
  
  # display the content
  ls "$dir" | while read parameter 
  do 
     printf "\t%s %s\n" "$parameter -->"  "$(cat ${dir}/${parameter} )"
  done 
  
done < mod.lis

After execution, I get "No parameters" for all modules
And it displayed "rm.shl command not find" at first line
I set [module name]=igb

Is anyone has further information about it? Thanks...
