9.Vendor details

  • cat /proc/cpuinfo | awk ‘/vendor_id/ || /model name/’

os name -> command - ‘uname -o’ cpu type -> command - ‘uname -p’ system name -> command - ‘uname -n’ os version -> command - ‘uname -r’ Processor Queue Length, Blocked Processes, Interrupts/sec, Context Switches/sec -> command - vmstat | awk ‘{print $1” “$2” “$11” “$12}’ Open File Descriptors - cat /proc/sys/fs/file-nr | awk ‘{print $1}’ CPU Cores - cat /proc/cpuinfo | grep processor | wc -l
