Clearcase：如何回滚特定分支上的所有更改？
问题描述：
我在错误修复分支上进行了错误修复，但是现在我需要回滚该分支上的所有更改。怎么做？我不想一个一个地恢复每个文件，：（。
I made a bug fix on bug fix branch, but now I need to rollback all change on this branch. How to do that? I don't want to revert each file one by one, :(.
答
我最近没有测试过，但是查看ClearCase安装中可用的perl脚本，该脚本名为 cset.pl （也在此处可用）：
I didn't test it recently, but check out the perl script available with a ClearCase installation called cset.pl (also available here):
ccperl cset.pl -undo myActivity
它应通过执行负合并（或次合并）来撤销活动）。
（也就是说，假设您使用的是UCM，因为您提到的是 changeset，即 UCM活动）
It should undo an activity by performing a negative merge (or substractive merge).
(That is, supposing you are using UCM since you are mentioning "changeset", which means "UCM activity")
