In the Powershell how can I extract 1000 characters before and after a found pattern
I have a large file (3mb) and I need to extract 1000 characters before and after a found pattern.
I am currently using
Select-String -Pattern "695614" in the Power Shell but this is printing out the entire file, there are not line breaks in this file.
Any idea?

I think this should handle that;
(get-content c:\somedir\somefile.txt -raw) -replace '.*(.{1000}695614.{1000}).*','$1'
