I am working with very large text files, consisting of very log lines (> 1000 characters per line). Using select-string to find a 10-character string in these files takes a couple of minutes. I am trying to find ways to optimize the search.Is there a way that I could restrict the search to certain characters of each line in the text file. For example, I might know that the string I am searching for is in position 350 to 352. Thanks for any assistance.
