The command "needrestart -k" is used to identify and restart the services or processes that need to be restarted after an operating system or kernel update.
Here's how the command works:
- "needrestart" is the main command that checks for processes or services that need to be restarted.
- "-k" is an option that tells the command to look specifically for kernel-related updates that require a restart.
When you run "needrestart -k", the command scans the system to identify running processes or services that are still using old versions of libraries or files linked to the outdated kernel. It then provides a list of these processes or services that need to be restarted.
By running this command after a kernel update, you ensure that all the processes on your system are utilizing the updated kernel and its associated files, improving stability and security.
