如何在CVS中还原已删除的文件?

我已经从CVS分支中删除了一个签入文件,即:
cvs remove -f file.txt cvs commit
如何还原文件?
解决方案
我相信:
cvs add file.txt cvs commit file.txt
...将从阁楼上复活。
我发现我们不能使用cvs add来撤消已经执行的cvs remove操作。所以这有效:
$ cvs remove -f file.txt $ cvs add file.txt
但这不起作用:
$ cvs remove -f file.txt $ cvs commit $ cvs add file.txt
到目前为止,我发现的最简单的方法是运行cvs status file.txt来查找版本号。然后获取修订的内容并将其添加回:
$ cvs update -p -r rev file.txt > file.txt $ cvs add file.txt $ cvs commit
鉴于哈利缺乏成功,以下是我为证明上述答案有效所做的成绩单(就其长度,我们先表示歉意):

显然,他在做正确的事情,但是他观察到的行为却有所不同。可能是由于CVS版本不同(我在Windows上使用的是1.11.22)。
cvs add对我不起作用,因为服务器上的cvs版本太旧了。我已经确认它可以在CVS 1.11.22版本中正常工作。
这是我的工作。我只是创建一个同名的空文件,然后添加并提交,然后检索较旧的版本并重新提交。
