The bash shell script below allows you to easily remove GNU/Linux kernels.

I suggest saving the script below as the file removekernel.bash and then making the file removekernel.bash executable:

#!/bin/bash
# TYPE: Bash script.
# PURPOSE: This bash shell script allows to easily remove GNU/Linux kernels.
# The script should be copied to /usr/bin/removekernel and set as executable.
# It is a poor man's alternative to Ubuntu Tweak.
# REQUIRES: bash, Ubuntu 10.04 LTS or newer
# REVISED: 20130302
# REVISED: 20130502
# AUTHOR: Mark Rijckenberg

if [[ $1 == "" ]]; then
echo "List of currently installed kernel .deb packages:"
dpkg --list | grep linux-image | egrep '^[r,i]i' | cut -d" " -f3
echo "No argument added after removekernel command"
echo "Please enter kernel package to uninstall from your pc (for example: linux-image-3.9.0-030900rc5-generic) "

echo "Removing kernel package $KERNELVERSION"
apt-cache search $KERNELVERSION|cut -d" " -f1|xargs sudo apt-get remove -y

Hi Mark,

Can i use this script in production servers(Now it is continuously
accessing by client).
Shall i do now. It may be affect the server performance or any other issues
will come.
Another one question. I already installed bash sh in the server . Is it
enough to run the script.

Regads,.
Ramesh

If you want to decrease any risks in production, I recommend running the script outside of office hours, when nobody is using the servers.

If bash is installed on the server, then you will be able to execute the script.

First make sure to set the script as executable by using this command:

sudo chmod +x removekernel.bash

if you saved the script using filename removekernel.bash

Hi Mark,
Sorry for the late response.
1.What are the images i need to remove from the server.
2.Do u suggest me reboot a production server once the image is removed.(I
need to reboot a server after removed images or before removing images).

A reeboot shouldn't be nesscarry as the images are not in use anymore. I'd just remove all non used images with this handy one-liner:
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

Be EXTREMELY careful with the command given by samuel.

I just tested the command on my laptop and it was ready to delete 1100 MB worth of packages (more than 144 packages) without asking.

You do not need to reboot after removing the kernel packages.

Remember: this is GNU/Linux, not Windows ;-)

I suggest deleting the old kernels that your servers are not using anymore.

Hi Mark,

Could you please explain how to execute the samuel command.
From the below details .How to remove unwanted kernel. Can you give me step

I discovered the following safer form of the command:

sudo dpkg -l 'linux-*' | grep -v libc | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

How to access the Terminal:

In Gnome (classic)

If you are using the Gnome interface, via "Applications->Accessories->Terminal"

In Unity

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that. So, the methods in Unity are:

Press CTRL-ALT-T key combination.

Dash > Search for Terminal

Dash > More Apps > 'See More Results' > Terminal

Dash > More Apps > Accessories > Terminal

Please copy-paste the command above into the Terminal to remove all previous kernels.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command on the page using the mouse. Move your cursor anywhere in the Terminal and press the wheel or middle button to paste the command.

Hit the <enter> key after copy-pasting into the Terminal.

Hi Mark,

We have gone through the below link,
http://markmcb.com/2013/02/04/cleanup-unused-linux-kernels-in-ubuntu/

Please note the article says *"Only run this if you’ve rebooted after
installing a new kernel*".

The Server is updated with new kernel, is it advisable to remove the old
kernel image without installing and rebooting the new kernel? please advice.

Thanks in Advance.

No, you need to reboot into the newest Linux kernel and thoroughly test it before uninstalling the old kernels.

That is my humble opinion.
