As a one-liner, awk-style?

  echo "Foo.1.2.3 = INTEGER: 1" | ruby -ane 'puts $F[3]'

In a ruby script?

  str = "Foo.1.2.3 = INTEGER: 1"
  a, b, c, d = str.split
  puts d

This is assuming the '1' you want is the one at the end of the line.

This question was asked in a very confusing way, I didn't realize `=
INTEGER: 1` was part of the input, I thought it was the result you expected
to get after doing some sort of analysis on the line above it.

Anyway, to expand on Brian's answer:

Josh has assumed that these are pairs of lines. I think this was just an
artefact of formatting by the OP's mail client, and they are really
single lines. In that case you just want the 4th column of each line:

ruby -ane 'puts $F[3]' < f

Oh, you're probably right. This was submitted via Ruby Forum, which does
wrap lines IIRC. No wonder the data was so confusing >.<

Is this a setting someone could turn off? I think it is objectively
incorrect to wrap lines for people. Their display software (in my case,
Gmail) should be responsible for determining the presentation settings
(line width), not the input source. The input source (Ruby Forum) has no
idea, and is making incorrect assumptions about my display, which is
causing problems.
