Programming :: Using Loops In A Search?
Jan 21, 2010
Code:
Title=
echo -n "Title: "
[code]...
hey guys, im doing a simple search program and i came up with a problem. What i am trying to achieve is, if the search is false(means the book does exist) , the program will then ask the user to input the information again(title and author) and do a search again until there is no such book and then display a message saying he can input a new book in.i tried using a until loop, but it does not seem to work. some guidance on how the statement should be and where should it be placed?

need to process files within multiple directories and transfer these to a remote server. What I had in mind was to use arrays for this; code pasted below (explains it better):
Code:
#set the arrays
array_A=( fileA* pathtodestA hostA passwordA )

Code:
#loop until there are no more files
while [ ${#files[@]} -gt 0 ]; do
for num in `seq 1 ${#files[@]}`; do
wurd=`tail -4 ${files[$num-1]}`
[code].....
Everything works.. but when it has to unset.. it breaks.. it doesnt give an error though.. it just jams the program.

How can i use grep (or any other command) to check for lines that begin with N number.
E.g. I want to print out commands (from history), but only from the command number 50 until #200.
This one doesn't work:
Code:
history | grep "^[50-200]"
Should print out something like:
Code:
50 cd ~/Desktop

I would like to make program that reads a *.TXT file and searches for last line and constatly refreshing the search. So last line would look something like this:Mike Had A 100.0 Pound Shark.So there are multplie category of "fish"(Shark, Dolphin, etc.) and each of them have allowed weight (ie. minimum 70.0 Pound Shark, 50.0 Pound Dolphin). If in the found sentence Shark or Dolphin doesn't meet requierments than program named False.exe should be started. I dont know how to make it my self so any help is much appreciated. My knowledge on programming is very low but I'm opend for learning.

I am looking for a one liner to search for a string in file(s) which are in a tar ball (.tar.bz2 in my case)
Code:
-bash-3.2$ tar -tjf /var/log/ABC/07142011-1412.tar.bz2
var/log/ABC/07142011-1412/
var/log/ABC/07142011-1412/live_hosts.txt
var/log/ABC/07142011-1412/all_hosts.txt
var/log/ABC/07142011-1412/LOGS.txt
How can I recursively look inside all the txt files in this tar file ?

I need to insert text ABCDEF starting at position 26 if a line starts with C. I need it to look like:
C 1VKNG ABCDEF 3097.00
C 1JLFU ABCDEF 3157.20
C 1MNVL ABCDEF 3346.10
I would prefer to use sed to do this and not perl.

I'm trying to use sed to search and replace backwards. The problem is that I have a shell script that is required to put commas into big numbers. For example
9999999 as 9,999,999
I've tried a few things, but none seem to work:
Code:
$ echo 9999999 | sed -e 's/([0-9]{3})/,1/g'
,999,9999
$ echo 9999999 | sed -e 's/([0-9]{3})$/1,/g' -e 's/([0-9]{3})/1,/g'
999,999,9,
$ echo 9999999 | sed -e 's/([0-9]{3})$/1,/g' -e 's/([0-9]{3})/,1/g'
[ode]....
It would be much easier if I could search backwards! For example Bash parameter substitution style:
Code:
$ echo 9999999 | sed -e 's%([0-9]{3})%,1%g'

yes, this is a homework question, but no - I'm not trying to get anyone to do it for me. I think that I am really close, but can't quite get one small aspect to work. in gawk, I want to include a variable name in the search string, but the below code doesn't work.
read -p 'Login name please? ' uLogName
userID=$(gawk -F: '/"$uLogName"/{print $3}' /etc/passwd)
echo $userID

i need to change a binary file, let's say to find and replace username:
find string: "/home/name/bla-bla-bla/ "
new string: "/home/anewname/bla-bla-bla/ "
i can do it, for example, in emacs (hexl-mode), but interesting in writing a script instead. it will be much more better for me if i could do it automatically. is there an analog of: sed 's/string1/string2/g' ? P.S. the best way is to recompile the binary files i have, but there are no sources available.

I've got a bit of an obscure question for you to test your brains a wee bit. I'm trying to implement a search program to find areas of high density in a binary string.
E.g.
Code:
[0001001010
0001110001
0000001000
1001000010
0101100100]
Where density is the number of 1's / number of digits with a maximum number of digits being the current number in a buffer (in this example 50). So for the example the density for the whole buffer is 15/50. But the density of Buffer[14..20]=[1110001]=4/7. So if looking for areas of density = 1/3 it would find the longest sequences of density over 1/3.So in the example. Buffer[4..9]=[100101]=3/6=1/2 which is above 1/3 but it is within the Buffer[4..48]=[100101000011100010000001000100100001001011001]=15/45=1/3

Any solution using awk/sed/regexp or other standard linux utility (this is for a mix of RH versions)? I am dealing with some very large application log files. I want to see everything that has been written to the log since the last application restart.
For an example take a log file like this:
Code:
# cat test.log
1 msg
2 msg
3 restart 1
4 msg
5 restart 2
6 msg
The following command is close to what I want:
Code:
# awk '/restart/,G' test.log
3 restart 1
4 msg
5 restart 2
6 msg
But the awk command grabs the first restart not the last. If it was working the way I wanted I would see something like this:
Code:
# awk '/restart/,G' test.log
5 restart 2
6 msg
So, I need something in that search pattern that says look for the last occurrence. I know how to do this with a pipe line - I could reverse the file and then do a similar awk and reverse back, or I could find the number associated with the last restart and then use that in the awk search. But these just take too long because the file is too big.

Im trying to read a file in c++ and search for particular character for example if this is a list that I have:
Alice
Bob
David
[code]....
if the input is D, it should give David, if its B, gives bob. so in this case, meaning it reads the first character of every line. but if possible I want to make this dynamic so the user can specify which character position he is looking for, so in case he is looking for R as character index 3 in all lines, it should give Charlie. but the problem is, it does now recognize , besides, I do not know how to specify the character position in each line.
here is my code
Code:
#include <iostream>
#include <fstream>
#include <cstring>
[code]....

I have an application with a complex binary build procedure which links against 30+ application library archives and an array of system library archives. The problem I'm having is the link ordering. Is there a way to tell the g++ linker to keep searching the libraries for unresolved references, regardless of order, instead of rearranging the order the archives are listed on the command line for a one-time-pass? I'm using g++ 3.2.3 on a Linux AS v3update6 machine.

I want to search for 1 file (say test.txt) on first server and all the output of this search to be greped as per my requirement and then transfered on the second server at the same location where they were on first server.
E.g.
output of search of file (test.txt) >> output.txt
/tmp/test.txt
/home/cpan/test.txt
/opt/cpanel/test.txt
Now I want to grep this output to only related to cpanel,
for f in 'cat output.txt'
echo $f | grep "cpanel"
if [ $? -eq 0 ]
then do scp.
But I am bit confused here, as in how to use scp command here.
scp $f root@second_server:/$f ?

Though I have developed some web applications (automation tools) using PHP which have been primarily meant for Intranet (within the organizations I have worked for), I have paid little attention to SEO (it was not required until now). But now I want to understand how do we go about implementing SEO and where do we fit this mechanism in a system / website?
Do we need any other tools or learn some specific programming /scripting language to achieve it?Will implementing a good SEO yield identical results irrespective of what search engine (be it Google or Yahoo!) is being used by users?

I have written a code on Linux that searches a long dictionary. I have used hsearch() function but the problem is it does not work. This is my code://Search the count values from the dictionary.
Code:
#define _GNU_SOURCE
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<search.h>
#include<inttypes.h>
#include<math.h>
[Code]...
I open each DIC file, get the word from it and search the hash table and extract the key from it. The problem with the above code is that it is able to make the hash table but it returns NULL when searching. It should not return NULL in any case because all words from DIC files are there in the dictionary. I am not able to figure out why?

I'm writing a script that edits a Maya ascii file. Inside the .MA(maya ascii file) there is a line defaultRenderGlobals. My script is supposed to find this line and according to what options they manipulate will update the lines below defaultRenderGlobals. I've got that working... but... the issue i'm having is that defaultRenderGlobals is only made when a the maya scene is made into a batch render. I want my script to manually addefaultRenderGlobals line into the .ma file if its not there and add the certain lines below it.RenderGlobals is already there I want to just manipulate whats below it. Hope this makes sense

i was wondering if in all the editors/tools in linux, if there was a prog that can extract a portion of a text file, giving it a starting line of say o as the first character on a line of say o35565 oxxxxx then when it finds the next line down the file with the same thing oxxxxwhatever
it could take those lines and all the lines between them and save it to another file? i dont know if you call this parsing? or what.

The goal is to auto-update a webpage that contains links to network devices. These devices are all set to DHCP, and their hostnames are not guaranteed to stay the same, so static IPs or accessing via hostname is NOT an option.
Process: Run a script every hour or so to query devices on the local network to generate a list of responding devices by MAC address and what their current IP is (results.lst). Using a "static" MAC address list file "printers.db" as the database search "results.lst" to find specific MAC addresses. When a match is found, grab the IP from "results.lst" and update "index.html" with the new IP address. No comparison needs to be done between "results.lst" IP and "index.html" IP as I just want to overwrite whatever is there.
Here is what I have so far (using dummy data): PRINTERS.DBProduct Mac Address Printer1 00:00:00:00:00:11 Printer2 00:00:00:00:11:11 Printer3 00:00:00:11:11:11 Printer4 00:00:11:11:11:11 Printer5 00:11:11:11:11:11 Printer6 11:11:11:11:11:11 TEST.SH

I'm writing an application and want to make possible to compile it with or without an optional module. This module requires perl library to be compiled, so I want to check presence of it in 'autoconf'.
The problem exists because perl library is placed in 'non-standart' location itself (like a /usr/lib64/perl5/CORE/libperl.so). So when I try to run configure (with AC_CHECK_LIB or AC_SEARCH_LIBS), it cannot find and link libperl.so in its test.
Trying to pass ./configure CFLAGS=-L/usr/lib64/perl5/CORE/ or ./configure LDFLAGS=-L/usr/lib64/perl5/CORE/
How can I define a location to search for configure's tests?
