I have an unusual problem. I am running a program that generates a list of file names (see example, CLUSLIST_5). In this file, there are several columns, of which only the first and the last are important to me. The first is a group number (1,2,3,4,5) and the last is a file name (tdump84...). The group numbers stay the same; there will always be 5 groups. The number within each group and the names of the files will vary. I would like to create a string of the filenames for each group. The group number is not needed as part of the string, but can be part of the string name. I have several hundred of the lists of file names, so I will need something that can be repeatable.
I can generate a string of file names, but I am struggling with the varying number within each group part. How should I begin to account for the varying number within each group?
The file isn't actually a text file. It is a text file for uploading purposes here.
Thank you much.
