Script to compile the linuxkernel in an easier way

[maximus]

A nice guy from our linux user group has wrote this script. I think i does a good job (Note: Script is for kernel 2.4.x)

Code: Select all

#!/bin/bash
#
# build - a handy script to build the linux kernel
#
# options:
# -f full, means it compiles the whole kernel including
# the modules and installs them.
#
# -o only, means it compiles ONLY this steps you
# you specify (see expl. of modifiers below)
#
# -s skip, means it compiles the whole kernel but SKIPS
# the steps you specify (see expl. of modifiers below)
#
# -h this help ;)
#
# modifiers:
# d dependents (or 'make dep')
# c clean (or 'make clean')
# z zImage (or 'make zImage')
# b bzImage (or 'make bzImage')
# m modules (or 'make modules')
# i modules_install (or 'make modules_install')
# to be continued....
#
# examples:
# to build the kernel but not the modules nor install them:
# ./build -s mi
#
# to build just the deps and bzImage:
# ./build -m db
#
#
# for any questions, send an PM
#

i am going to have to try that out.
