Linux lilo Command

Linux Command Manual

The Linux lilo command is used to install the kernel loader and boot manager.

lilo (Linux loader) is a Linux system kernel loader that also has boot management capabilities. When executed alone, the lilo command reads the /etc/lilo.conf configuration file and installs lilo based on its contents.

Syntax

lilo [-clqtV][-b&lt;device identifier>][-C&lt;configuration file>][-d&lt;delay time>][-D<label>][-f&lt;geometry file>][-i&lt;boot sector file>][-I<label>][-m&lt;map file>][-P<fix/ignore>][-r&lt;root directory>][-R<command>...][-s&lt;backup file>][-S&lt;backup file>][-uU&lt;device identifier>][-v...]
