General :: Finding Data From A Text File?
Mar 22, 2010
I'm trying to write a shell script which finds bits of data from a text file. at the moment i'm using grep and basically i need a function which will look through the text file and take the data out of it. the file has days, months, years etc and i want it so i can type feb 06 and it finds all of the data for feb 06.
the problem i have is i can type feb and all the information comes back for feb, but i can't get it more precise e.g. feb 2009 and it finds just feb 2009, it seems to ignore that latter half. I've tried experimenting with egrep and having two inputs but i can't seem to fuse them together, it only takes the first input.

I'm having a slight dilemma on reading data from a text file and outputting it into a table then displaying it. Basically I'm writing a shell script that takes information from text files then outputs the data into a table with 4 headings.he extracting of the data is fine, but creating a table i'm having problems with. I think it is possible to do it using the awk function, but so far i'm having a lot of difficulties.

i need a php script to format and display a select amount of text from a file or a cron job that'll do it (with grep etc) and out put to a file but whatever is easier i want to display all the banned ip's i have in my .htaccess file i have a lot of lines in my .htaccess file but i have a line that read like this:
Code:
RewriteCond %{REMOTE_ADDR} (123.123.123.123|123.123.123.123|123.123.123.123)$
the 3 test ip's are 123.123.123.123 and i want the "" stripping and the "|" removing and each ip to be on it's own line like this:
123.123.123.123
123.123.123.123
123.123.123.123
i'm not bothered if this is a php script that'll read the .htaccess file and display the output or a cron job that'll run every x mins and output it to a .txt file but i'd prefer a php script

I am writting a program that reads a text file (music.txt) & stores it in a Data Structure. I am a novice learning over the internet so I this is something I have never done. How do I do this?
Quote:
Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?
Code:
#include <iostream>
#include <fstream>
#include <strstream>

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

I deleted files on my linux drive that I shouldn't have. What is a good tool to use to recover these files that will:
Recover the various file types (txt, php etc)
Recover it as the original files names
TestDisk and PhotoRec almost do the trick, but the original filenames are not restored.

I copied a back up of my windows 'my documents' fold and all of its' sub folders into my linux (Mint Debian) Documents directory. I found that many of my files can be found in more that one directory so, what I want to do is to find all the dups and deal with them. Is there a good linux application to resolve this 'duplicates' problem. (I don't want to touch the linux system files.)

How could I replace text in one file with text from another file using sed?
The text in each of the files would be surrounded by a starting and ending delimiter or a starting tag, say like /* */ so to easily find them.

['3', '1', '3', '-1.5768747']
['4', '1', '3', '-26.4772491']

im trying to output a list of running processes via a shell script. At the moment i got this which outputs the processes to a text file called out.
echo $(ps aux) >>out
The problem is though, the processes are all just one big block of text which makes it hard to read. Does anyone know how to sort the output to a text file so that it prints to the text file at 1 process per line? I know its probably simple but im very new to linux.

I have some music files (.mp3 and .flac) which have unmodifiable tags: After I change the tags, they revert to their original values automatically. It's not related to access permissions (using Linux) as in a same directory, with the same permissions, some files have modifiable tags and other not. Is there such a thing as "protected" or "unmodifiable" tags? Are there solutions to force modification ?

Basically, I am trying to locate and copy the newest .json bookmark backup in my .mozilla/firefox/w987sdg9.default/bookmarkbackups directory.
I tried this
Code:
ls -t ~/.mozilla/firefox/b1ahb1ah.default/bookmarkbackups/ | head -1
which does return the newest file, but only the filename itself. I found readlink, but I haven't gotten that to output a full path which I can then feed to copy. So, it seems to me that find might work well here, and I know how to find based on absolute dates, but not relative.

If there is a command I can use to find specific file types? Say if I want to find all the jpg's in my home folder, but they don't have the .jpg extension in the name, how would I do it? Or can I set some kind of size parameter to find them? The ones I want are all from my digicam and roughly the same size.
