I want to return logs with line

Process1A
Process2A
Process3A

The log file can have process 1A to 1000A or 1B to 1000B and so on but I only want to see process 1A to 3A. I dont want to include ProcessA (without 1, 2 or 3 in it) only in my result set. The log line has lots of information so character "A" can exist elsewhere in the line. I want to check the string specifically in the examples I listed above.

So something like this:

grep Process[1 or 2 or 3]A.*Result=Running scrape.log

but I dont know how to specify [1 or 2 or 3] with regexps.

You have two ways for expressing OR:

  1. Character classes: [abc] for disjunction of characters
  2. Groups: (string1|string2|string3) disjunction of strings

So in your case you could use Process[123]A. See demo.
