I'm looking for a way to grep things like: i log for E M, i 1 f x i 0, I xi 1, 3 1,.
simply based on number of characters.
Nothing in that hypothetical output is longer than three characters. This hypothetical one-liner would look something like, grep -v [:alnum:] > {3}
. (Except I just don't know how to write that in grep syntax.)
,
and.
as part of a word?
