Howdy folks,
I'm trying to craft a log file summarisation tool for an application that creates a lot of duplicate entries with only a different suffix to indicate point of execution. I thought I'd gotten close but I'm clearly missing something.
Here's a genericized version:
A text_file (infile_grocery.txt) with these contents.
What I'm hoping to get is:
The command line I've cooked up is:
But the results I'm getting are:
Clearly I'm skipping chunks of lines somehow but I've been staring at this too long and I can't see it. Anyone have any suggestions for me?
Seems simple but I am having difficulty with this one: I am trying to write a single command line argument (which will be a path) - the program should print out the owner of the path.
I can not get anything I write to run.
Please help. (5 Replies)
