I have a multitude of files (2TB) which all have word data in them. All the data follows the same format but the information slightly changesI need to be able to pull out specific data from the files but the wording slightly changes in each file. For example in some files the words are server123 whilst in others they are server345.Add to that, the fact that I need to then pull out other information from the same file which go with the server such as IP addresses also found in the file and be able to identify where that came fromSo I need something like <server123> 20.40.15.1634.45.56.67etcJust to clarify server123 is in the same file as the IPs I need and server 345 is in a different file with the IPs I need. This continues throughout.  The files are in the same folder.Is it possible to write something like this from command line or do I need a python script or something.
grep-ing - I think
grep
