For instance, the grub entry for the kernel I'm running right now:

title 3.8.0-rc6-next-20130206
        kernel /vmlinuz-3.8.0-rc6-next-20130206 ro root=/dev/mapper/vg_blackice-root log_buf_len=2M vga=893 loglevel=4 thre
adirqs intel_iommu=off LANG=en_US.UTF-8
        initrd /initramfs-3.8.0-rc6-next-20130206.img

(Strictly speaking, it's not the grub command line, it's the kernel command
line that is passed to the kernel by grub or lilo or grub2 or syslinux
or whatever boot loader happens to float your boat).
