问题描述
我想在ClearCase中查找带有特定标签但没有设置其他标签的文件.
I'd like to find files in ClearCase that are labeled with a specific label but that do not have any other labels set.
例如，如果我有这样标记的文件:
For example, if I have files labeled like this:
file1 LBL_A, LBL_B
file2 LBL_A
我想查询一个仅提供file2而不是file1的查询.
I'd like to have a query that gives me just file2 and not file1.
有没有办法使用cleartool查找?如果使用单个查询无法做到这一点，那么我将对如何分几个步骤进行操作的任何想法感到高兴(我将从perl脚本中调用cleartool，因此可以很容易地保存文件列表并在其上运行进一步的命令.
Is there a way to do this with cleartool find? If this is not possible to do with a single query, I'd also be happy for any ideas how to do this in several steps (I'll be calling cleartool from a perl script, so it will be easy to save lists of files temporarily and run further commands on them).
非常感谢！

推荐答案
假定LBL_A是您要运行的(唯一)标签
Assuming LBL_A is the (only) label you want running
cleartool find /some/dir -version 'lbtype(LBL_A)' -print | xargs cleartool describe -fmt "%n: %l"
应该给予
file1: (LBL_A, LBL_B)
file2: (LBL_A)
作为输出，然后您可以在perl脚本中检入或通过sed -n 's/\(.*\): (LBL_A)/\1/p'进行过滤(假设文件名中没有冒号).
as output which you then can check in your perl script or filter through sed -n 's/\(.*\): (LBL_A)/\1/p' (assuming no colons in filenames).
更新:正如VonC正确指出的那样，上面的命令对于包含空格的文件将失败.要以以下方式运行该文件:
Update: As VonC correctly points out, the command above will fail for files with spaces in. To handle that run as:
cleartool find ... -print | tr '\012' '\000' | xargs -0 cleartool ....
这会将换行符转换为ascii null，然后让xargs将其用作分隔符.
which will translate newlines into ascii null and then have xargs use that as delimiter.
