Red Hat / Fedora :: How To Locate Words In A File
Jul 6, 2010
I am using Oracle Enterprise Linux version 4 update 7.
Sometimes I have to access large files with thousands of lines in them and I would like to locate a particultar word. e.g.
vi /etc/passwd.
The contents of file passwd are displayed.I want to find a username of joe assuming the passwd file is 2000 lines long.
I would like to use a linux command that will locate joe and highlight in the passwd file as to where word joe is.
Is there a linux command that can do this?

I am trying to match a file consisting of words to many separate other wordfiles in a specific directory. one by one.
What i want the script to do is to report how many matching words my main file has with every file in the directory, each in turn
setup:
Each of em are plain text files with 1 word per line
Output should be something like:

I tried Suse five or six years ago and ran into an issue that was not comfortable to work with so I went back to windows. The problem was open spaces between words was not permitted with my music files. I have transferred all of my CDs and LPs to MP3 and have a tremendous number of them and the Suse of five years ago required I convert a title like Foggy Mountain Special.mp3 into something resembling Foggy_Mountain_Special.mp3
I don't care to convert literally a hundred thousand titles to fit the latter format. Does the current version of Suse allow the use of spaces between the words or is the 'no open space' convention still required?

i have this file, and considering it's obnoxiously huge i'd prefer not to have to do this manually. Is there some way i can manipulate sed or awk to change every other letter in all the words in a file to capital letters?

i want to remove words "Max" and "constrained" in a file given below:
Max 0.003745 constrained
Max 0.004549 constrained
Max 0.001689 constrained
[code]....
and further want to replace "Max" by line number so that i can plot the resulting file. i searched in forum, but couldn't do what i wanted to do. e.g. i used
1)grep command
grep -v "Max" inputfile >outputfile
deletes whole line,and hence whole text.
2) sed command
cat inputfile |sed 's/ .{1,12} //g' >outputfile
gives output
0.003745constrained
0.004549constrained
0.001689constrained
[code]....

I am basically trying to remove duplicate words in my <title></title> tag after I got hit by Google Panda. I have around 750 .html files and it will be difficult for to me remove one by one. I am looking for a way to remove only from within <title> </title>
Example of a duplicate title I have:
Code:
<title>Pasta, Pasta Recipe and Pasta Guide</title>
I dont want to replace those words anywhere else in the file except for within the <title>

I have a text file that gets produced at the end of the script being run.
For this example the text file will produce the following:
Quote:
THE COW
THE DOG
THE CAT
THE HORSE
In the script I am using either echo or printf to print on the screen each line and then it is doing a test and produces a good or bad result.
Another example:
Quote:
THE COW -- IS HOME
THE DOG -- IS HOME
Each whitespace between the -- are 5 spaces. How can I get them to be in-line and formatted when it gets to more words, when THE HORSE arrives.
Example:
Quote:
THE COW -- IS HOME
THE DOG -- IS HOME
THE CAT -- IS HOME
THE HORSE -- IS HOME <-- This has only 3 whitespaces but is still formatted.

cat sorted_noapostrophe.txt| grep '.{3,4}'
but it returns no results? Also to find any words starting with 'f' which are between 3 and 5 characters (inclusive) long, how can this be done?

I'm trying to highlight some key words as tailing a log file using a perl script; about my case: I want to search for a keyworrs just once and highligt all occurrence of them. I want just highlit the keywords but not the whole line but the problems are that perl just catches the first keyword in a line and skip checking for other occurrence. for example if a line like "Error: some exception happen, Unable to process" it just highlight the error and do not process the remain part of the line where it should hilight the word "exception" and "Unable"
2-How can I do some action if for exapmle at least 4 time "unable" message appear ( not just in one line but diffrent line)in below is how I use perl search and replace : Code: s/(?:(unable|exception|warning))/e[1;31$&.......

A long time ago I wrote a short essay about the 'federal' 'reserve' board. I don't remember it's name or format. I think it's somewhere on my rather large hard discs (to of them divided into various partitions).I'm trying to write a command line that will find it based on a quote that is in it: "our fathers brought forth"I have tried various configurations of grep, and or combining grep with find, but I'm getting nowhere. I really don't understand the syntax of either command, or how they work together, and the examples that I can find are really no help at all.

I am reading a book on OpenSSH and I need some help on sshd2_config . I cannot locate this file. The author claims that it should be in /etc/ssh2/. I don't see the ssh2 directory either. Is this another component that is not installed? Since the book is an implementation book, it doesn't give all the details as to what it is. It assumes you know.

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.

What is the best way to locate a file or folder in your hard drive? I have been trying to do that through searching in "Files & Folders" but it seems that the search is not thorough: it doesn't look for everything. I have an external drive that when it's connected to the computer I would like to search inside of it as well. The "Files & Folders" option does not seem to do that at all.

I'm getting this when I try to do an upgrade in Adept in Kubuntu:APT Error. Context:Package download failed,I wasn't able to locate file for the libvolume-id0 package. This might mean you need to manually fix this package.
When I try apt-check in the console, I get this: The package libvolume-id0 needs to be reinstalled, but I can't find an archive for it. How do I manually fix this package?

I'm new to bash scripting and I've searched around the forums and Internet for this but haven't had any luck. I've found similar things but not what I need. What I need to do is write a simple script that uses what the user inputs to locate and display where a file is. I would prefer to use locate instead of find since I know that the person I am writing this for has locate on her machine (my mom, who is just beginning with Linux).I'm writing the script to make things easier for her while she learns In this particular part of the script I would like to be able to have the script prompt to enter the file she is searching for, read the her input and then display for her where the file is. I realize it would in most cases be much simpler just to teach her how to use locate, but she is very impatient and this is just a part of the script I will be writing, but I can't figure out how to do this.

I seem to have removed / moved / deleted my /etc/apt/source.list file and was wondering where or how can I locate them again on the web? Is there a place online that has the default repository listings for 'Etch' & 'Lenny'? I did not lose them on both but this is something I would like to know in case it ever happens to me. Seems like this would be something easily available on the web but I can't find it on Debian's site and or via Google.
