pretty easy.  lets say you have a variable called “flagFile” that contains the name of a file with a .flg extension.  you can do the following:

Code:

set datFile “[ file rootname $flagFile ].dat”

OK I’ve worked out how to do it. In unix:

set fname [ls /export/home/cloverleaf/capture/*.flg]

You could use the tcl glob command which returns a list of all entries found matching a glob pattern. I would use the nocomplain switch so that an empty set would not throw an error.

If you are concerned that a subdirectory might match the pattern, you could then work the list using ‘file isfile’ or ‘file isdirectory’.
