ClearCase Support: Common ClearCase Error when Running Cleartool Commands
Here is another common error message that I am asked about a lot.
cleartool> lsview | grep username
cleartool: Error: No matching entries found for view tag "|".
cleartool: Error: No matching entries found for view tag "grep".
cleartool: Error: No matching entries found for view tag "username".
This error message, "cleartool: Error: No matching entries foundů", is caused because the user assumed that the cleartool prompt is a DOS or UNIX prompt and can run DOS or UNIX command from the cleartool prompt. However, this is not true. You can not use any DOS or UNIX commands, in the case the "| grep username" arguments, on the cleartool prompt.
A simple workaround is to exit out of the cleartool prompt, and run the command directly from DOS or UNIX, like this:
$ cleartool lsview | grep username
That should solve the user's problem.
