<0> Hi. What is a good way of printing every field except the first one?
<0> From the man page: "Decrementing NF causes the values of fields past the new value to be lost, and the value of $0 to be recomputed, with the fields being separated by the value of OFS."
<0> But how can I decrement NF? I tried several things.
<1> redondos: print line excluding first word: awk '{for (i=2; i<=NF; i++) printf("%s ",$i);printf ("\n")}' filename
<1> print line excluding first word: awk '{ $1 = ""; print }' filename
<0> Awesome, thanks.
<0> gnubien: Can you think of a way of doing it with the second command you suggested but also removing the leading space?
<1> maybe
<1> # delete leading whitespace (spaces, tabs) from front of each line awk '{sub(/^[ \t]+/, ""); print}'
<1> http://www.student.northpark.edu/pemente/awk/awk1line.txt
<0> Nice.
<0> Is that page yours?
<1> lots of cool tips at that url
<1> no, i b just a awk user too
<0> k :)
<1> only be learning awk for about 6 months, always a newbie tho
<0> How would you print just the last line here: awk '/asdasd/ {$1 = ""; sub(/^[ \t]+/, ""); print $0 | "sort" }'
<0> I can't think of a good way where to use END.
<1> # print the last line of a file (emulates "tail -1") awk 'END{print}'
<0> I got that, but where should I fit it in my statement?
<0> I'll just use tail for now.
<0> That page is really useful, thanks for that.
<1> awk 'END{print}' filename | awk '{ $1 = ""; print }' |awk '{sub(/^[ \t]+/, "");print}'
<1> i havent figured out how to combine awk without pipes yet; maybe a function would do that
<0> Ah, 'print' is the same as 'print $0'?
<0> album_id=$(awk '/asdasd/ {$1 = ""; sub(/^[ \t]+/, ""); print $1 | "sort"} | tail -n 1')
<0> That's what I'm currently doing.
<0> Doing all in one awk script would be nice.
<1> no sort with awk
<2> Heh.
<2> You guys are really geeking out tonight :)
<2> Kudos.
<1> pr3d4t0r: yea, we b havin fun now ;)
<1> pr3d4t0r: know how to chain awk commands together without using pipes?
<0> Yeah, I'm trying to write a script to resize and upload pictures to a remote gallery2 (gallery.mentalto.com).
<0> And awk has helped me greatly.
<1> cool, awk is really uber-powerful, great utility
<1> redondos: google gawk manual for lots of info
<2> Ah, argentino.
<0> :)
<0> Where are you from?
<2> redondos: Mxico.
<0> Nice.
<0> Sorry for the World Cup elimination.
<0> Not that a geek would care, anyway. :)
<0> Hey, the script is finally working. Neat.
<2> Indeed.
<1> great
<2> redondos: I'm not shocked. We have some of the best players in the world -- as long as you don't put them all to play in the same team.
<0> pr3d4t0r: Heh, I didn't know that was the general feeling in mexico.
<1> http://www.grymoire.com/Unix/Awk.html
<2> redondos: I don't know what the feeling down there is like, but I bet it's similar ;)
<2> redondos: I haven't lived there in a long time.
<0> I see.
<0> gnubien: Is that the recommended tutorial?
<1> http://www.vectorsite.net/tsawk1.html not official but good
<1> http://www.grymoire.com/Unix/Awk.html really good and easy read
<1> http://www.faqs.org/faqs/computer-lang/awk/faq/
<0> Swell.
<1> cool, awk is easy to learn so i bet you will learn it fast
<2> redondos: If you promise to be a good boyscout, and not to publish this bookmark...
<2> redondos: Check your private messages.
<0> pr3d4t0r: I haven't gotten any. :/
<2> redondos: Check now.
<0> Oh, there we go.
<2> redondos: Just keep that one to yourself. Some of those e-books, uh, fell off the back of a truck.
<0> :)
<0> There's little about awk, though.
<2> redondos: Only one awk reference, from O'Reilly. That's probably all you need anyway.
<0> Yeah...
<2> redondos: Also, if you get the urge to download that let me know and I'll give you the URL for a CD .iso image instead that you can fetch with wget and pace down the rate of download.
<2> redondos: That server is my gateway and it's under somewhat heavy use.
<0> pr3d4t0r: I'd be glad to have that CD image.
<2> redondos: Do you know how to pace wget?
<0> yeah
<0> Just tell me what rate you want me to limit it with.
<2> --limit-rate, set it to around 20 KB/s and you'll be golden so that other people keep good service to the server. Check your private messages in a few moments.
<2> Grrr...
<2> redondos: Hold on; I think I clobbered it by mistake.
<2> redondos: Let me check my backups.
<0> OMG.
<2> redondos: Well, here's the good and the bad news.
<2> redondos: It's backed up -- that's not a problem.
<2> redondos: That's the good news.
<2> redondos: The bad news is that it's backed up in a remote server so I need to bring it across first, and that will take a while.
<0> pr3d4t0r: No worries, just please ring me a bell whenever it's ready. :)
<2> redondos: If you don't mind, check with me tomorrow. I'm more-or-less always around IRC :)
<0> k
<2> redondos: It looks like I found a DVD backup here. Stand by.
<0> k
<2> redondos: Checking...
<2> rdir -s /home/ciurana
<2> ...
<2> Sorry.
<2> Hah!
<2> I just found my C++ code from 1990 - 1996.
<0> Heh...
<2> redondos: Ping me tomorrow - no luck right now.
<0> k

<6> "Recovered by intelligence agent pr3d4t0r (JANAP/299: ZEPHYR) and recently decl***ified."
<6> heh..
<2> Shush!
<2> genocide: :)
<6> :P
<6> but is there any truth within that story? i dont know much about tesla's work
<6> nor his history..
<6> i am not very well educated..
<2> genocide: All the Tesla-related stuff is based on facts known and documented about Tesla's life and work.
<6> really ?
<2> genocide: Really.
<2> genocide: Fact-based fiction is where it's at, baby!
<2> :)
<6> did the us.gov burrie his work ?
<2> genocide: Yup.
<6> omg
<2> genocide: Through the Office of Alien Property, though by then Tesla had been a US citizen for over 40 years.
<2> genocide: That sheet that pr3d4t0r "recovered" is really a document obtained through FOIA.
<2> genocide: It's a real document. I think I lifted that one from the PBS Tesla web site.
