General :: Search Within A Log File Within A Time Range
Jun 24, 2011
I 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.

How do you find a file modified March 17, 2010, between 3:30 pm and 4:05 pm? I know that I must be missing something somewhere.How do you search for info like this? I goggled "search files time Linux" and got about 38,300,000 results. I looked through the first four pages and did not see what I was looking for.Do I need to calculate how many minutes ago that is and give that to find.I really want to do this in the GUI so that I can operate on the files found without typing in so much stuff.

I'm trying to find a proper command to move a certain set of files according to date/time range. I am thinking that the command should be something like:
Code:
ls -l | grep 'date/time range' | mv /folder

I downloaded Ubuntu 10.04 yesterday and installed using Wubi. I have downloaded ndiswrapper and ndisgtk and installed the drivers for my wireless adapter. My last question is how to make Ubuntu actually search for a wireless network in range like Windows does. So far, I like Ubuntu but want to connect to the 'net.

I have data that looks similar to this -
Quote:
John Smith (Address)
123 Main St
Unit 1
[code].....
So I need everything between each name, but I am not guaranteed that each time I match a name that I will have the same amount of lines, so I do a range pattern search line this to get all lines, no matter if there is 5 or 10 or 15. I simply do a loop that goes through the whole array until I hit the match, and this is my search pattern.
Code:
if ($LINE =~ /^s+$SELECTED_NAME/ ... $LINE =~ /(Address)/) {
push @ADDRESS_INFO, $LINE;
}
This works perfectly... until I hit the end and it doesn't get its final pattern match because it's at the end and there is no next entry with a (Address) line. So as a 'hack', I ended up inserting a final scalar at the end of the array that just says (Address) so it knows it's at the end. Ideally though, I'd like to do an "or" statement that says search for Address || return true if I hit the end of the array. How would I match on "End Of Array" essentially?

I have a file generated in every event occurred. In this file i have a entries like bellow
<without blank line after Summary>
Summary: Adapter at hardware path 0/6/1/0 :Received an interrupt indicating that a
primitive was transmitted
and sometimes like bellow
<with blank line after Summary>
Summary: Adapter at hardware path 0/6/1/0 :Received an interrupt indicating that a primitive was transmitted What I need is to extract the Summary from the file. I have the following awk script. But it only works if there is no blank line after Summary.
cat server.event.txt|awk '/^Sum/,/^$/'
But I need up to second blank lines after Summary.

I have a doubt, i have a file which contains around 3000 elements, now i want to search for an element in that file.what will be the Efficient way of searching ? without consuming much memory and time..
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..

I 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.

Im 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.

I have a file called Regions.ini that looks like this:
Code:
[Granite]
RegionUUID = 54ab7cd2-0e70-49b7-8020-8dbeb84c08d0
Location = 9991,10007
InternalAddress = 0.0.0.0
InternalPort = 9001
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9
[Syenite]
RegionUUID = 8fc56fdd-0afd-4074-9432-0ae8f42b799f
Location = 9992,10007
InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9
What I need to do is find out what the IP address is after "ExternalHostName ="
After that I will need to compare that IP to whatismyip and if it's different then replace it but that is easy to do with sed. I just can't figure this simple hurdle out.

I'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?

Is it possible to locate the Firefox file that retains "Search" history (not particularly "Browser" history)?I have lost a hardcopy list of authors and titles of books/ebooks that I search the web for. However, most of the time when I would enter a name or title a drop down list would have that entry I wanted, and I could just click on it. That drop down list is what I am calling "Search" history.

I need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:
number="1234567890"
number="22390"
I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.
