This would yield all lines from your sample above but suppress many other text lines. If it's too open, try narrowing it down by becoming more specific, e.g. on the year numbers:
Code:
$ grep -E "([A-Za-z]+, [0-9]{4})" file
(Daviis, 2004)
(Schultz, 2000) and (White, 1989)
(Sutter, 1987; Reid and Shapley, 1992)
(Enroth-Cugell and Robson, 1966)
(Barlow, 1961, 1989; Atick and Redlich, 1990; Atick, 1992)
(Dong and Atick, 1995a)

And, yes, as Scrutinizer proposes, you may want to use the [[:upper:]] and [[:lower:]] classes.

Greping in between two different lines.

I know you could use the grep "something" -A200 flag to get all the lines past your pattern. Is there a way to get all the lines in between two patterns? The -a flag will not work since all lines in between the two patterns don't have a constant number. (4 Replies)

NAME
grep - search a file for lines containing a given pattern SYNOPSIS
grep [-elnsv] pattern [file] ... OPTIONS
-e -e pattern is the same as pattern -c Print a count of lines matched -i Ignore case -l Print file names, no lines -n Print line numbers -s Status only, no printed output -v Select lines that do not match EXAMPLES
grep mouse file # Find lines in file containing mouse grep [0-9] file # Print lines containing a digit DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1 occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is returned. SEE ALSO
cgrep(1), fgrep(1), sed(1), awk(9). GREP(1)
