I have a very large file with millions of entries identified by @M. I am using the following script to "extract" entries based on specific strings/patterns:
I believe it would be more "cost-effective" to reduce the "size" of the input file by eliminating the entries that have been already "extracted" during the initial loops. Thus, by the time the last strings are being searched, the processing time would have been significantly reduced. I was wondering what would be the most efficient way to accomplish such task considering that I am dealing with a sizable infile?
Thanks in advance!
I want to search a file for a string and then if the string is found I need the line that the string is on - but also the previous two lines from the file (that the pattern will not be found in)
This is on solaris
