ClearCase:查找仅具有一个特定标签而没有更多标签的文件 [英] ClearCase: Find files having exactly one specific label and not more

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.
