Hello friends,
I'm trying to grep out sentences. The sentences are previous to an academic citations in a pdf. The goal is to get summaries of citable work.

Her is what I tried reading the MAN page.

Code:

pdftotext foo.pdf | grep -A 5 ***chose reg expression below*** 


pdftotext BioPsych10.pdf | grep -A 5 \([A-Z]*[a-z]\,[1-2][0-9][0-9][0-9]\)

It pauses, but doesn't produce anything. Also it would be nice if I could stop printing at the start of the desired sentence, instead of 5 lines.


These are the regular expressions I will use.
(Daviis, 2004)

Code:

\([A-Z]*[a-z]\,[1-2][0-9][0-9][0-9]\)

(Schultz, 2000) and (White, 1989)

Code:

\([A-Z]*[a-z]\,[1-2][0-9][0-9][0-9]\) and \(, [A-Z]*[a-z]\,[1-2][0-9][0-9][0-9]\)

(Sutter, 1987; Reid and Shapley, 1992)

Code:

\([A-Z]*[a-z]\, [1-2][0-9][0-9][0-9]\; [A-Z]*[a-z] and [A-Z]*[a-z]\, [1-2][0-9][0-9][0-9]\)

(Enroth-Cugell and Robson, 1966)

Code:

\([A-Z]*[a-z]\-[A-Z]*[a-z] and [A-Z]*[a-z]\, [1-2][0-9][0-9][0-9]\

(Barlow, 1961, 1989; Atick and Redlich, 1990; Atick, 1992)
(Dong and Atick, 1995a)

Code:

\([A-Z]*[a-z] and [A-Z]*[a-z]\, [1-2][0-9][0-9][0-9][a-z)\)

Thank you for taking the time to read this. Please let me know if you have any ideas.
