bash提取svn的Revision

目标拿到svn的版本号作为打包的名称
svn info，先看一下svn的信息都有哪些

➜ svn info  
Path: .
Working Copy Root Path: /Users/wuyutao/.jenkins/workspace/test/client/abc
URL: svn://192.168.8.1/test/client/abc
Relative URL: ^/client/abc
Repository Root: svn://192.168.8.1/abc
Repository UUID: db3bce81-f136-4b22-aeb7-036094440344
Revision: 9145
Node Kind: directory
Schedule: normal
Last Changed Author: Admin
Last Changed Rev: 9145
Last Changed Date: 2021-12-09 12:44:11 +0800 (四, 09 12 2021)

我想把Revision: 9145，中的9145，拿到作为包名abc_9145.apk

➜ svn info | grep Revision                        
Revision: 9145

怎么拿到9145呢，于是网上一顿搜索bash正则替换

➜ svn info | grep Revision | sed "s/Revision: //g"
9145

成功拿到9145，sed命令格式sed 's/oldValue/newValue/g'，在这里我是吧字符串Revision:替换成了空字符串。
然后放到一个变量中待用

➜ svn_ver=$(svn info | grep Revision | sed "s/Revision: //g")
➜ echo $svn_ver
9145

参考：
linux sed 正则提取字符串,Shell中使用grep、sed正则提取和替换字符串
