I've written a script that you can place in /usr/local/bin and execute each time you want to see what kernel you are using, the uptime and the kernels installed on your system. Here it is: #!/bin/sh # # The purpose of this script is to query which kernel # is currently running on your system... # # # July 25, 2003 by Ed Gurski (ed@xxxxxxxxxx) # KERNEL="`uname -r`" # Get the name of the current kernel UPTIME="`uptime`" # Determine how long the system has been running RPM="`rpm -qa|grep kernel-2|sort`" # Show all installed kernels on this system clear echo "" echo $UPTIME| while read a b c d e f do echo "As of $a the system has been up for $c days and $e hours" done echo "" echo "The running kernel is =====> $KERNEL" echo "" echo "The Kernels installed on this system are:" echo "$RPM" echo "" ============================================================ and a sample output would look like this: As of 15:13:14 the system has been up for 6 days and 2:45, hours The running kernel is =====> 2.4.22-1.2174.nptl The Kernels installed on this system are: kernel-2.4.22-1.2166.nptl kernel-2.4.22-1.2174.nptl Enjoy...
