Is there a way to include the sentence before the citation?

Yes, instead of the -A5 option you used before try -B5. AND, read the man page.
BTW, this would not yield the sentence but the last 5 lines before. If you go for the sentence, this will become awkward...

This regex seems to also return the required output:

Code:
grep -o "([^)]\+ [0-9]\{4\})" file

But it will fail on the citations spread on multiple lines as in:
Quote:
symptoms of schizophrenia, and they are now
used more widely ( J. M. Davis, Chen, & Glick,
Compared to drugs like haloperidol, the second-generation
2003; Edlinger et al., 2005). Clozapine is generally considantipsychotics
Suggestion, first get rid of all CR before running the grep thing.

Edit:
Try this:
Code:
tr -d '\n' < file | grep -o "([^)(]\+ [0-9]\{4\})"

I saw on anther board:
"awk '/word1/', will print out the whole sentence, when I need just a word1."

I would love to have that kind of problem. Putting in user ripat's awesome regular expression
Code:
tr -d '\n' < BioPsych10.txt | awk /'([^)(]\+ [0-9]\{4\})/'

returns nothing.

I think it is interrupting it as text and not as regular expression.

How far do you get with the -B5 option?

B5 cuts some sentences short or leaves a lot of garbage.

It was implied that I can get just the sentence and the citation using awk. Digging through the man page and google searches implied that
Code:
awk '/word1/'

spit out the whole sentence. Does anyone know if I can do that with regular expressions? I tried in my previous post.

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)
