脚本集锦

每个人的mac地址都不一样,这个脚本可以保证每个人生成的uboot的唯一性.

#! /bin/sh

cat $UBOOT_NAME /tmp/pad.bin >/tmp/tuboot_0x1fc00.bin

echo "Backup some config first,just like MAC address ..."
dd if=/dev/mtd0 of=/tmp/config.bin bs=1 skip=$((0x1fc00))

cat /tmp/tuboot_0x1fc00.bin /tmp/config.bin >uboot.bin

--- Openwrt 的懒人编译脚本，送给爱跟trunk同步升级的强迫症党

老爱编译trunk最新版本的朋友用这个脚本鼠标点击运行即可，通过make menuconfig保存好默认的编译配置

更新svn后，按Y/N 选择是否运行make clean，然后开始编译了。。

复制如下内容保存成 build.sh 放到openwrt /trunk目录下。默认是16线程编译，cpu不够强大的把16改成其他数字即可，比如2~4.

#!/bin/bash

svn up
./scripts/feeds update -a
./scripts/feeds install -a
make defconfig

echo "Make clean? Please answer yes or no."
read YES_OR_NO
case "$YES_OR_NO" in
        yes|y|Yes|YES)
                make clean
                make V=99 -j 16
        ;;

        [nN]*)
                echo "DO NOT make clean!"
                make V=99 -j 16
        ;;

        *)
                echo "Sorry, $YES_OR_NO not recognized. Enter yes or no."
                exit 1
        ;;
