ClearCase: Find files having exactly one specific label and not more

Question

I'd like to find files in ClearCase that are labeled with a specific label but that do not have any other labels set. For example, if I have files labeled like this: ``` file1 LBL_A, LBL_B file2 LBL_A ``` I'd like to have a query that gives me just file2 and not file1. 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). Thanks a lot in advance! Jan

Accepted Answer

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"
```

should give

```
file1: (LBL_A, LBL_B)
file2: (LBL_A)
```

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).

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 ....
```

which will translate newlines into ascii null and then have xargs use that as delimiter.
