    Question Remove old kernel(s) via command line?

    Hi!

    My server has lots of older kernels on it. If I have already booted up the latest kernel, is there a way to delete the old ones with the command line? (no GUI)

    Thanks in advance!
    If it jams, force it. If it breaks, it needed replacing anyway. . .
    I like Unity.

    sudo apt-get remove <kernel>
    There are two mistakes one can make along the road to truth...not going all the way, and not starting.

    Thanks! That was easier than I expected.

    OK, now I am being told that I may have to re-run my bootloader [grub]. How might I go about this?

    Thanks in advance!

    are you using grub?

    on a server?

    multi-boot?

    I'm using grub (v1.5, I think), and Ubuntu is the only OS.

    grub shouldn't be necessary if Ubuntu is the only OS...

    strange...

    Ubuntu is the only OS, but something still has to load the kernel and initramfs, correct?

    .
    Bootloader is always necessary, not just for dualbooting. You need something to load the OS kernel into RAM to boot the OS, the only difference between Grub and for example NTLDR or winload.exe/Windows Boot Manager (used by Windows, NTLDR in Windows NT variants and WMB in Vista) is that Grub has better support for booting other operating systems than just the one it was made for.
