This is true but in fact it is even easier, when values are adjacent. You won't even need extended regexps for this:

Code:
grep  '^[^,]*,[^,]*,22[34],'

search for '...' followed by "22", followed by either a "3" or a "4".

Such "character ranges" can do many things, here are a few examples:

"[a-z]" search for a single lowercase character

"[0-9]" search for a single digit number

"[0-9]*[02468]" search for an even number

"+*[0-9][0-9]*[^.]*" search for a positive integer (an optional plus-sign, followed by a non-zero number of numeric digits, followed by anything except a comma)

I hope this helps.
