1) is this efficient if i take all the 3000 elements from file to a list or array and sort them and search ?
2) or is it efficient to search directly inside the file ??
Can anyone please suggest some algorithms for an efficient way to search in this case ?I am using C for coding..

View 2 Replies View RelatedI used locate cmd to search file abc.txt (for example) as I didn't know in which directory it would be present and couldn't find it. But when I did find . -name abc.txt, it traced the file, luckily the file was in the same directory. I am wondering how find was able to search abc.txt and locate not. How these two are behavinb differently? Usually I use locate when I don't know the path to the parent dir.
View 8 Replies View RelatedI want to search in my apache log, for events which have occurred say between 11:00 AM to 2:00 PM. I have got few scripts/commands but they are not conclusive, some of then are trying to do an exact match(awk) and for some i am just getting the pattern wrong (eGrep)
I am running RHEL.
Apache log eg:
================================================================
10.92.120.129 - - [24/Jun/2011:01:29:07 -0500] "GET /favicon.ico HTTP/1.1" 302
================================================================
now if i want to find out the logs from 1 PM to 2 PM
some example i had was:
cat <apache.log> | grep -E '07/Apr/20110[1-2]:[0-5][0-9]|02:00)'
small script in which i can pass the start time and end time range, and it should give an output of the rows which fall under that time range.
What keyboard shortcut will give me a regexp reverse search in bash? Or does C-r supply something like that already that I can't figure out?

View 2 Replies View RelatedIm new to the forum and fairly new to Linux as well. my apologies if this is posted in the wrong section. My problem is How can you search for a file in multiple machines (like a server farm) ? For example i log onto machine num1 and want to search for a file named "xxx.yyy" which may be in one of 4 machnies. What i do right now is manually log into each machine and run the find command. However i have heard that it is possible to do it via a couple of simple commands. I have looked into pssh and cssh as well as ssh tunneling (along with public key authentication to stop the machines requesting a password every time i log in) and unfortunately i was unable to find an answer.

View 10 Replies View RelatedI've got a big text file in which I know have probably made some typos (LaTeX). Sometimes I rewrite sentences several times and then end up with double pieces like "the the" or "is is" without noticing it. Most spell checkers that I can use in LaTeX are very basic so they do not notice these grammar errors. Is there a way that I can search for these repetitions by hand using sed or awk or something along these lines? Is there an app for that?

Upon a while of searching, I think I failed to find the correct terms and I'm posting here. I often use mlocate to search for files. For example, if I say
Code:
$ mlocate temp_2.pdf
I'll get two results:
Code:
/home/kmc/Documents/latex/temp_2.pdf
/home/kmc/Documents/latex/test/temp_2.pdf
Now if I want to open one of them, I'll have to either open Acroread and browse to their locations. Or select and copy, and call acroread in terminal like
Code:
$ acroread /home/kmc/Documents/latex/temp_2.pdf
This is tedious to me. I'm thinking of a way of quickly open its search results, I've tried pipes like this but it doesn't work:
Code:
$ mlocate temp_2.pdf | acroread
maybe it doesn't work this way. So what does the trick? What's the name of this trick? I've googled for
Quote:
Linux bash catch output, pipe output, open mlocate results And is it possible to handle multiple lines of output, e.g., can I choose which line of output get forwarded to relative programs?
