# CheckKernel checks if Kernel was updated and not aktivated (rebooted)

# (c) GPL by Ulf Bartholomäus ub1x@gmx.net
|

VERSION="$( basename $0 ) Version 0.2.3 from 12.7.2021"
|
||||
#
|
||||
# Input: 1 parameter optional ("-d" = debug and "-v" = verbose / "-D" = Distro only / "-K" = running KernelVerion / "-N" = New Kernel Version)
|
||||
# Output: text messages and a kdialog if this is installed
|
||||
# Returnvalue: 0 if Kernel OK and 10 if Kernel is changed
|
||||
#
|
||||
# ToDo: Check if initrd and vmlinuz exists
|
||||
# cat /etc/issue
|
||||
# cat /proc/version
|
||||
# Error: inxi - hangs in a script:
|
||||
# MyDistro="$( eval inxi -xSz | grep Distro: | awk -F'Distro: ' '{print $2}' )"
|
||||
# https://github.com/smxi/inxi/issues/181
|
||||
#
|
||||
# Changes:
|
||||
# 0.2.3: Fix error => update in case only one Kernel is avaialble
|
||||
# 0.2.2: Fix error => new Kernel update: replace initrd with vmlinuz check
|
||||
# 0.2.1: added -D -K and -N option
|
||||
# Fixed error and exit with more than one /boot/initrd-* file
|
||||
# 0.2.0: InitKernel und VmlzKernel entfernt,
|
||||
# [ $( ls -1 /boot/ | grep initrd- | wc -l ) -gt 1 ] && echo "** Error" || ls -1 /boot/ | grep initrd- | cut -d '-' -f 2,3,4
|
||||
# Some small changes and simplifications
|
||||
# 0.1.9: NewKernel erneut angepasstsys
|
||||
# 0.1.8: "==" -> "=" sowie kleinere Shönheitskorrekturen - sowie NewKernel mit awk statt cut
|
||||
# 0.1.7: remove "CheckKernel.sh: Zeile 33: lsb_release: Kommando nicht gefunden."
|
||||
# and => -d = debaug
|
||||
# 0.1.6: if "lsb_release" not available use "cat /etc/*-release" info
|
||||
# 0.1.5: Fix trouble if NewKernel is empty
|
||||
# 0.1.4: Fix some errors
|
||||
# 0.1.3: Fix running and new kernel are equal but shown as different
|
||||
# 0.1.2: Remove "initrd-" from InitKernel
|
||||
# 0.1.1: Add Kernel Info in kdialog
|
||||
# 0.1.0: exchange some direct calls against definition
|
||||
# add check if new Kernel is in GRUB Config file
|
||||
# 0.0.7: read Kernel version from menu.lst
|
||||
# 0.0.6: add verbose mode
|
||||
# 0.0.5: syslog messages
|
||||
# 0.0.4: returnvalue if Kernel is changed is 10
|
||||
# 0.0.3: hostname in kdialog title
|
||||
# 0.0.2: kdialog output
|
||||
# 0.0.1: generation
