how I can do the following in a bash script?
1) Load all *.log files into an array variable
2) Iterate through the array, and do a "grep" on each of the file to see if it contains a "word".
To start, I'm writing a script to check a file's date via FTP. Here's the portion that I'm having problems with:
Code:
function checkRemote
{

I need to kind of grep within grep. My input file would be something like:
[Code]....
and I need to find the first occurrence of hello before MY PATTERN (hello 9008 in this case), so the output should be:

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
ls: cannot access grep: No such file or directory
[code]....
When I type in the command directly, without using an inbetween variable, it works fine.

I am interested in using the grep method in the shell of my CentOS machine to obtain patterns from a file and use them to search through another file and highlight the patterns found. For example:
pattern file:
one
two
three
test file:
AAAAAAAAAAAAAAAAAAAAAoneAAAAAAAAAAAAAAAAthreeAAAAAAAAAAAA
I want to know that is there any method to grep a particular data from a file without using the "cat --- | grep ' ' " command....I need to use a system call for this functionality.

View 5 Replies View RelatedI 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

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:
Code: grep -L -f file_one.txt file_two.txt > output.output Here's some example data:
Code:
>FQ4HLCS01BMR4N
>FQ4HLCS01BZNV6
>FQ4HLCS01B40PB
>FQ4HLCS01BT43K
>FQ4HLCS01CB736
>FQ4HLCS01BU3UM
>FQ4HLCS01BBIFQ
how to increase efficiency or use another command?
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>

I need a loop that pulls out the user name into a variable and then pulls out the LastUpdate field into another variable so I can then perform a comparison against the last update field. Requirements are AIX tools including AWK, SED and Perl I am writing a script to check AIX users password expiration dates and if they are within the alerting period (ie. 7 days etc) it will email the user. I will release the full script into the public domain once completed. The text file I want to parse is formatted like:
Code:
colettel:
password = XSON0m4SdIQDw
lastupdate = 1260829398

View 3 Replies View RelatedI am running after compiling a program and I find that I get the following. How best can I avoid this as i cannot run the program.

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.
When I hardcode abc.bin to inputFileName - I can open the file in cpp. But when I pass the same using an optional argument, it fails. Note that in both cases, fprintf, prints the inputFileName as abc.bin properly.
I get can't open - no file or directory.
Code: main()
{
char * inputFileName;

inputFileName = optarg; //doesn't work.

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>

I'm trying to backup every night a big directory (~2.5Gb) using tar+gzip.I'm calling tar like this:nice -n 19 tar --ignore-failed-read --exclude-tag-all=.kein-backup -Pczpsf '/backup/20100925233802f/archive.tar.gz' '/srv/products'And in 90% of the cases works just fine, in about 20 minutes is everything done. However, if it happens that in those minutes one file or folder from '/srv/products' gets deleted it reports me the following error:tar: /srv/products/prod14564.gif: Cannot stat: No such file or directorytar: Exiting with failure status due to previous errorsDoes it exist a parameter for tar to ignore this kind of errors? Is it there any other way to avoid these errors
