You should be aware of several things that can catch you:-
  • Using egrep is the same as grep -E so the string passed is an Extended Regular Expression. Along with | as an 'or' separator, it also means that the . is a wildcard for a single character. Searching for 192.168 will also match 192g168
  • You can group expressions or characters using [expression] so you can consolidate your search/exclude.

I'm not clear what the overall requirement for this is, but I think you are looking for sessions for user mickey that are/aren't from a specific set up IP addresses. Might I suggest:
Code:
egrep -v ^host=192\.168\.1\.10[123]|192\.168\.1\.123

If this is all there is, then it may be to better blend these together like 192\.168\.(10[123]|123)




I hope that this helps,
Robin
