Programming :: Locate A File By It's Contents?
Jul 16, 2011
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 trying to read the contents of a file into something else. I have a file.txt that I am working with, I want to read the file and take the data and run some commands with the data that it read. So if it read www.yahoo.com I want to be able to nslookup. Does that make sense? I have been trying to use the read command but that does not seem to work. I even was trying to read filename | > filename to see if I could even read any of the data at all. Nothing is working.

want to watch the file continoulsy for any newly written data to file.Presently i am periodically opening the file and checking for the newly updated contents.Is there something like refresing the file descriptor, since open is a system call, calling it many times may affect performance. Does the tail program opens file multiple times to check for the updated contents when used with -f option.Can some one explain or give some links on how the filedescriptors remembers its end contents while some other programs keeps updating the file.

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.

How can read the file /var/etc/allInOne.cfg and distribute its contents on multiple cfg files using C language. /var/etc/allInOne.cfg contain the data and the path of each text file.
The source file "/var/etc/allInOne.cfg "look like this:
line1
line2
...
line10
filePath:/var/etc/file1.cfg
line12
line13
...
line14
filePath:/var/etc/file2.cfg
linen
..
filePath:/var/etc/filen.cfg
the result will be :
The expected result is:
/var/etc/file1.cfg will contain line1 to line10
/var/etc/file2.cfg will contain line 12 to line13
/var/etc/filen.cfg will contain linen to linen-1

I have multiple HTML files in a folder. there is a <h2> tag like this:
Code:
<h2>some text</h2>
in each file. I want to write a shell script/batch file to add this tag in <head> section of each file:
Code:
<!-- TITLE= "same text from h2 tag" -->
Note that <h2>some text</h2> in some files has 1 or more linebreaks and so I couldn't capture tag content using a simple grep or...
for example:
<h2>first part of text
second line of text</h2>
The line break shouldn't be shown in <!-- TITLE= "same text from h2 tag" -->. The script has to capture tag content & skip line breaks.

I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

someone once told me that use can pass a file to grep and use that to search the contents of another file. if that is the case I'm not entirely sure why the following isn't working for me.
Code:
[root@LCENT01:~]#grep -i id_rsa.pub .ssh/authorized_keys
[root@LCENT01:~]#cat id_rsa.pub >> .ssh/authorized_keys
[root@LCENT01:~]#grep -i id_rsa.pub .ssh/authorized_keys

When I eject CD from CDROM by pushing eject button(mounted on CDROM) it still shows CD and it's contents in nautilus file browser. If I replaced the CD it still shows contents of older CD. If I eject CD manually by file browser then there is no such issue. I know this is the kernel issue because this issue has come after updating my kernel from linux 2.6.33 to linux-netbook-2.6.35. I am using MeeGo. I want to know which kernel parameter(or module) I have to add.

I have a fresh dedicated server that im currently configuring and needed a little help if I may ask.The problem is that i'm having a file naming issue. for example from the web I can access any file that does not have spaces of any type. ex/music/musicfile.mp3this works fine and my php script can locate itBut the problem is when I try to access a file that has spaces.ex/music/The Eagles - Hotel California.mp3my php script can't seem to locate any files like this with spaces but doesn't have a problem locating the files with no spaces.
I also took a look at the directory within shell. I did notice that files that have spaces are showing up in this formatt in shell.#/home/~username/public_html/music/The Eagles - Hotel California.mp3In shell , i'm assuming that unix/linux maybe adds a backslash before spaces. But when I FTP to this same directoy, the filename look normal and at windows standard. how could I correctly access these types of files within my php scrits? or would I need to have all uploaded files renamed so that spaces are replaced with underscores maybe?

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 in the process of writing a program that plays the game mancala. I wanted to create a function that requires the player to choose a number between one and six, should be simple right? I kept having problems, so I started testing stuff out.

short move();

I am using gcc version 4.3.2 (Debian 4.3.2-1.1). On a whim, I tried something else out; when I change the 'short' variables to 'int' , the problem seems to dissapear.... I tried changing the format string in the scanf statement from "%d" to "%u" which is listed as the appropriate string for the 'short' type, still no luck.

I know that I can do something along the lines of
Code:
touch /var/www/index.html | echo "echo some contents" >> /var/www/index.html
but would like to do this without having to specify the directory again with echo, and maybe even use linebreaks / tabs on the echo in. Anyone know a neat one liner?
