分享个精简ipk包的shell脚本用来精简固件

dato

本教程适合喜欢openwr.org官方固件，完全掌握了使用imagebuilder生成自定义固件的高级玩家。像咱这种菜鸟只会删软件包，还到达不了从源码精简掉help文件那种要求。
以前都是本地用7zip下载回来删除再上传回vps，无奈最近网络实在太慢了，今天花了点时间折腾了一下，挺好。这种比官方的好用，官方的方法做出来的固件最后用7zip是无法打开的。

使用方法
1,定义好自己需要精简的包
格式为
IPKrm stunnel  #用于shell grep IPKrm处理快速生成列表
stunnel.conf libstunnel.so ./usr/lib #定义需要删除的文件，目录以空格做分隔，保持1行用tr生成排除列表

2,将代码复制到imagebuilder/packages目录里处理就可以了，处理好的文件放在packages/IPKG_REBUILD目录
3,如果确认没问题就可以通过 cp -a IPKG_REBUILD/* ./packages 覆盖同名文件
4,重新用imagebuilder生成固件就可以了。

脚本对完整*.ipk解包data.tar.gz，排除掉不需要的文件重新打包成data.tar.gz，再重新打包成精简*.ipk。
通过删除不需要的文件来达到精简固件的目的。

openwrt的原始方法，大家可以参考一下，最大的问题做完的镜像用7zip无法打开

1. ===根目录建立files_remove
   
2. 1. Create file 'files_remove' with full filenames:
   
3. 
   
4. cat << EOF > ./files_remove1
   
5. #多余目录
   
6. /usr/lib/opkg/status
   
7. #/usr/lib/opkg/info/*.list
   
8. /usr/lib/opkg/info/*.control
   
9. /usr/lib/opkg/info/*-pkg

黯然老混

厉害！能详细说下怎么使用呢？

dato

1. cat << EOF > /tmp/IPKrmlst.tmp
   
2. IPKrm softethervirtual**
   
3. virtual**cmd
   
4. 
   
5. IPKrm stunnel
   
6. stunnel.conf libstunnel.so ./usr/lib
   
7. 
   
8. IPKrm sexpect
   
9. sexpect
   
10. 
    
11. IPKrm vlmcsd
    
12. ./usr ./etc/init.d
    
13. EOF
    
14. cat /tmp/IPKrmlst.tmp

复制代码

使用方法
1,定义好自己需要精简的包
格式为
IPKrm stunnel  #用于shell grep IPKrm处理快速生成列表
stunnel.conf libstunnel.so ./usr/lib #定义需要删除的文件，目录以空格做分隔，保持1行用tr生成排除列表

2,将代码复制到imagebuilder/packages目录里处理就可以了，处理好的文件放在packages/IPKG_REBUILD目录
3,如果确认没问题就可以通过 cp -a IPKG_REBUILD/* ./packages 覆盖同名文件
4,重新用imagebuilder生成固件就可以了。

脚本对完整*.ipk解包data.tar.gz，排除掉不需要的文件重新打包成data.tar.gz，再重新打包成精简*.ipk。
通过删除不需要的文件来达到精简固件的目的。
