Grep

Help a fucking retarded winfag out with a stupid fucking dumbshit problem? Thanks.

TL;DR dumbfag trying to use grep in Cygwin and failing.

Goal: extract only words beginning with un- from a very large text file (or multiple files) and output all matches to a file. Needs to be only single words starting with un-, not whole lines where matches are found.

Problem: can't figure out how to pull out the whole word instead of just the "un." grep " un" gets me all the lines containing words starting with "un," but that's no use, and grep -o " un" is just going to return "un"s. How do?

Why I want to do it, in case you're interested:
I'm trying to do a bit of linguistics research by identifying "ungrammatical" constructions where the affix un- attaches to a noun base. This is generally considered ungrammatical by English speakers (e.g. *uncup, *unbook, *uncomputer), but there have been some notable exceptions and I'm looking to identify them in the works of certain authors historical and present. Since I'm working with a rare construction, there's no surefire way to filter out the non-noun parts of speech from my search, so I just have to sort through everything starting with un-.

fuck fag fuck shit fag
Yeah, this is someone I really care to help.

This might be more to your liking:
I know the problem is one that should be easy to solve, and google is a very impressive resource indeed, but it seems I have no choice but to petition you fine gentlemen for assistance due to my inexperience in scripting-related matters.

Who are you quoting (is that even a quote?), >>2 never said such things!
Also, sage your posts and don't use /b/speak, only retarded use it.
>>1
$ grep 'un' files ...
You can go back to /b/ or /g/, now.

^un
Lines starting with un.

>>3
>4chan
Maybe you should go back there.

grep -Eio '(\bun\w+)'

>>2,4,6
Fuck off, ``faggot''. Too busy to choke on nigger cocks to help, aren't you?

>>8
Why faggot in quotation marks?

Are you ``retarded''?

>>8
Too busy not getting the /b/ scum leak inside /prog/? Yes.

>>10
Hah, I'd rather have him around than cock-sucking faggot elitist ``LISPPERS'' like you.

>>11
Then you may want to go back to /code.

>>12
Why don't you go somewhere else? It would certainly make this a better board. This place is highly un4chanish.

>>4
I don't do high horse bullshit. I'd be fine with anon saying, "Please don't use such language, we're all sophisticated gentlemen here," if he dislikes the stylistics of my post. I'm not fine with the self-aggrandizing, autistic mentality behind, "lol i not help but i rite condescending poast so that internets know i cool kid who so indifferent to other people's expectations." My post addressed the board generally, not "village neckbeard 3."

Also, that won't work.

>>5
Not looking for that.

>>6
herpa derpa, pardon me for intruding upon the super secret treehouse meeting.

>>7
What is this doing? I understand the -io, but not the regular expressions stuff.
Thanks.

>>13
Why don't you go somewhere else? It would certainly make this a better board. This place is highly 4chanish since you came.

>>14
-E activates extended grep.
-i and -o you already know.
\b means word boundary.
\w means alphanumeric. (see the grep manual breathing page)
something+ means ``at least one occurrence of something

Cheers

>>8,9,10,11,12,13
Do you guys just sit around and troll each other all day as a general hobby?

>>16
Oh, regular expressions aren't complicated at all. They're just generalizations of string characteristics. Is the + specifying that there should be at least one alphanumeric character in addition to "un"?

>>17
We used to, but since >>13 decided to act like an imageboard retard, it's just an endless succession of ``noko'' and ``go back to /b/''.

Optimize your quotes: >>8-13

>>18
Is the + specifying that there should be at least one alphanumeric character in addition to "un"?
Yes, it will match ``una'', ``undefined'', but not ``un''. If you want to match zero or more character after ``un'', use \w* instead of \w+.

Ok, so one more question:

1) Does
grep -Eio '(\bun\w+)'
pick up every match, or just the first on every line?

>>21
Herpa derp, I originally had two questions and left the numbering.

>>21
Every match. You could confirm this easily on your own.

>>23
I thought that was the case, but something in the grep man pages about file types made me unsure.

Thanks, all done.

>>24
Awesome. Does that mean you will stop bumping this thread now?

>>24
You're welcome :)

>>21
Every match in the file(s).
grep -Eio '(bunw+)' file
grep -Eio '(bunw+)' file files ...

>>22
Herpa derp
Seriously, don't speak like that here, we don't like it, they will mark you as ``imageboard retard'' and will not help.

>>25
Look at the other threads on the front page. Then back at this thread. Then at the other threads. Then back to this thread.

>>27
Blubbity, blub bleab blib blab bleb, bleh bloh blaib blib, bleyh bleeh blab bloo blas ``I am a cock sucking textboard autist'' blab blib blob bleb.

>>28
The only salient difference is that some of the other threads are about programming. And their authors don't respond to each and every troll. Bump bump bump!

>>28
It's sad because you're right.

>>29
Ungrateful piece of shit.

>>32
I'm not OP, I'm the ``faggot'' guy.

>>33
Oh well carry on then I guess. You ungrateful piece of shit, you.

>>33
At least you admit you're a faggot.

>>35
Man I wish either of you had at least grade school level reading comprehension.

>>33
nice dubz bro.

OP here, came back because I figured the trawling would continue. I'm
>>1,3,14,18,21,22,24
and that's it.

Stop trolling yourselves. No more posts from me.

>>38
Trolling is breathing to us.

>>39
Trolling is now breathing manually.

>>40
I hate you.
