Version control Rancid/VieWVC-cvs-仅保留最新版本/删除旧版本

我使用Rancid和ViewVC作为“前端”，用于查看网络设备的配置文件

我只想保留所有设备的最新版本号，并删除旧设备

cvs -d /usr/local/rancid/var/CVS rlog Switches

输出示例：

只是为了测试一下，从

/usr/local/rancid

我试过了

cvs -d /usr/local/rancid/var/CVS admin -o :"1.1" Switches

但是

cvs admin: cannot open CVS/Entries for reading: No such file or directory
cvs admin: nothing known about 1.1.1.1,v

cvs管理员：/usr/local/rancid/var/cvs/Switches/configs/1.1.2，v:Revision rev 1.1不存在

尝试使用特定文件：

cvs -d /usr/local/rancid/var/CVS admin -o :"1.1" Routers/configs/1.1.1.1,v

 cvs -d /usr/local/rancid/var/CVS admin -o :"1.1" /usr/local/rancid/var/CVS/Routers/configs/1.1.1.1,v 

但是

cvs admin: cannot open CVS/Entries for reading: No such file or directory
cvs admin: nothing known about 1.1.1.1,v

---

好的，算出了，只需退出`/usr/local/rancid/var/”路径，例如/tmp

和类型

cvs-d/usr/local/rancid/var/cvs校验开关

然后执行

cvs -d /usr/local/rancid/var/CVS admin -o :1.1 Switches/config/1.1.1.1

并删除所有带有1.1的修订
