automatically remove
The command below can automatically remove unused Kernels.sudo apt autoremoveManual removal
1. View the Kernel in use
View the currently used kernel, such as my current Kernel
4.4.0-104-generic
uname -rView the currently used kernel, such as my current Kernel
4.4.0-104-generic
Do not remove the Kernel in use!
2. View all kernels in the system.
3. Remove unwanted old versions of Kernel
I want to remove multiple brace expansions that can be used in bash.
The command above removes three at a time.
linux-image-4.4.0-92-generic
linux-image-4.4.0-96-generic
linux-image-4.4.0-97-generic
If we only want to remove a specific kernel on the system.
