Mar 16, 2010

I ran into a bit of trouble making a bash script. (Desktop is a directory, and I try to get it's modification date)

Code:

lamp:~# cmd='ls -l Desktop | grep -o "....-..-.. ..:.."'
lamp:~# $cmd
ls: cannot access |: No such file or directory

[code]....

When I type in the command directly, without using an inbetween variable, it works fine.

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

[Code]....

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.

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:

how to increase efficiency or use another command?

Programming :: Using Grep And Regular Expression To Find Class References In C++ File?

May 28, 2010

I'm trying to math all class references in a C++ file using grep with regular expression. I'm trying to know if a specific include is usuless or not, so I have to know if there is a refence in cpp. I wrote this RE that searches for a reference from class ABCZ, but unfortunately it isn't working as I espected:

grep -E '^[^(/*)(//)].*[^a-zA-Z]ABCZ[]*[*(<:;,{& ]'
^[^(/*)(//)] don't math comments in the begging of the line ( // or /* )
.* followed by any character

[code]....

Well, I can get patterns like this:

class Test: public ABCZ{
class Test: public ABCZ {
class Test : public ABCZ<T>

Programming :: Make A Folder For Each File In A Directory Then Move The File Into It

Nov 29, 2010

Initially I thought - use a for loop with ls in it:

Code:

However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).

The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.

char * optarg;
inputFileName = optarg; //doesn't work.

Debian Programming :: No Such File Or Directory

Sep 18, 2015

I’m new to C programming so I wrote the following program to see if everything I needed to write programs with GCC and the standard C library was already installed. I am having issues in OS 10.10.5, where I am unable to build and compile some simple code, either using Xcode or Sublime text. I decided to install Linux Mint in Virtual Box to see if it would work.

Code: Select all#include <stdio.h>
void main()
{
 printf("Hello! This is my first C program with Linux Mint
");
}

For some reason, I'm getting the following error:

mint@mint-VirtualBox ~/Desktop $ gcc hello.c -o hello1
hello.c:2:19: fatal error: stdio.h: No such file or directory
#include <stdio.h>
