General :: Sed/awk/grep Search For Number String Of Variable Length In Text File?

Jan 19, 2010

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.

Programming :: Grep Multiple Values In Single Pass Through Log File?

Nov 13, 2010

I have a huge binary log file. There are lets say 4 id's that I want to find in a log file. I know that those 4 id's will be present in the log file and I also know in what order they will be present. I want to find 1st id from the log then 2nd id and then third id and so on..

Simple/inefficient solution is: Loop through the id's and then grep in the log file. Problem with this solution is for each id grep will search from the beginning of the file.

Better/efficient solution would be: Sine I know the order in which id's will be present in the log file. Loop through id's, grep 1st id and then move on to grep 2nd id and so on...this way I can grep all id's in one pass. Is this solution possible ?

I have 500000 + values to find in log files and I have to find efficient solution for it.

Programming :: Storing Grep Output To Feed Awk To Retrieve Entire Records Matching Variable

Jul 28, 2010

I have two files :

FileA
prot1
prot5
prot9
prot15

[Code]....

What I need to do is to extract from fileB the fields containing only the strings in fileA.

I thought awk could do the job easily with :

Code:
awk 'BEGIN { RS = "###" } /'$variable'/' fileB > output

where variable would maybe be the output of grep from fileA. So can I store the output of grep in a variable to use it afterwards with awk ?

something like that:

Code:
result=`grep prot. fileA` ; awk 'BEGIN { RS = "###" } /'$result'/' fileB > output
but that doesn't work. I'm always getting the entire fileB.

The output of grep get stored in the variable, I verified that with echo. So there is something that I just don't get... It seems to me that the above line should work.

Programming :: Splitting A File Based On The Values Read From An Input File?

Jul 27, 2010

I am splitting a file based on the values read from an input file. The below one is the script.

1)How do I add the header which is present in the original file to the new split files created?(For eg. pharmacyf conatins header as table column names. The new files created (ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat) are without the header).

2) Also the script is creating 0 byte files for the pharmacyids which are not available in the intial file? Can this be avoided?

for pharmacyf in *
do
tablename=`echo $pharmacyf |cut -f4 -d'.' `
while read pharmacyid
do
grep -w $pharmacyid $pharmacyf >> $OUT/ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat
done< inputfile
done

Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?

Aug 21, 2009

I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.

For example:

Code:

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

Programming :: Make A New Variable With The String From The Old Variable Btut Without Any Plus Sign?

Programming :: HUGE Files - Compare A List Of Patterns From One File And Grep Them Against Another File And Print Out Only The Unique Patterns?

I am trying to compare a list of patterns from one file and grep them against another file and print out only the unique patterns. Unfortunately these files are so large that they have yet to run to completion. Here's the command that I used:

Code: grep -L -f file_one.txt file_two.txt > output.output Here's some example data:

Code:

how to increase efficiency or use another command?

Programming :: Sed - Save Output To File With Filename From Content Of Another File?

Feb 28, 2011

My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Ive named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:

sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.

Programming :: Sorting Specific Values From An XML File

Sep 21, 2010

I need a shell script which gathers the data from a remote XML file and then displays it according to my needs.. I need this for my job due to the fact that I need to keep track price changes of euro, usd, gold, etc. The XML file I am talking about is located at this page: here. The reason I am posting the URL is that I need to use curl to get this file and it does NOT have newlines after each tag. I thought that that would be a problem. Here is what I need from the script: 1) curl to get the page 2) make use of sed, awk, etc. to display its contents in a more structured and readable manner as shown below:

A: 64.125 (% -0.26)
B: 81.130 (% -0.32)
C: 1.4930 (% 0.00)
D: 1.9590 (% 0.36)

Programming :: Fork() - Variable Values Between Child And Parent Process?

Feb 24, 2010

Code:

int main()
{
int pi;
int i=10;
pid=fork();

[code]....

Q 1. The value of the variable pid returned by the fork() function will be greater than 0 in the parent process and equal to zero in the child process? but during forking, there values are exactly copied so what's went wrong here?

Q 2. "changes to the variable in one process is not reflected in the other process" why it is so? >> Even if we have variable i declared as a pointer or a global it wont make a difference.

Code:

int main()
{
int i, pid;
i=10;
printf("before fork i is %d

[code]....

Q. Through this program it is clear that both process is using the data from the same location, so where's the original value is residing when the child process is in execution.?

Programming :: Grep A String With Space?

Feb 9, 2010

I am using Sun 5.9.

I am putting the value "Feb 10" in variable 'c' here.

Code:
-bash-3.00$ c=`date | awk '{print $2 " " $3}'`
-bash-3.00$ echo $c
Feb 10

But when I am grep-ing value of 'c', I am getting this error.

Code:
-bash-3.00$ ls -lrth | grep $c
grep: can't open 10

This is because there is a space between "Feb" and "10".

Programming :: Perl - Grep Open File More Then Once?

Jul 16, 2011

I am using File::Find to go through a very large tree. I am looking for all xml files and open only those that contain a tag <Updated>. I then want to capture the contents of two tags <Old> and <New>.

My problem is, after I open the file and do the first grep for <Updated> (which does work), I am unable to grep again unless I close the file and open it.

I did something like this:

Quote:

find(&check, $dir);
sub check {
if ($_ =~ /.xml/){
open(FILE,"$_");
if (grep{/Updated/} <FILE>){ # <-- works
