Server :: Remove Dynamic String Across Multiple Lines And Files?
May 13, 2011
My server was hit with an injection script which has placed code across many of my clients files. I need a script that can remove a block of php code that spans multiple lines, multiple directories/files and is dynamic, meaning that part of the code changes. I think using find/sed is what I need but cannot seem to figure out how to get it to work.The following is the script that is being injected everywhere. The catch is that they have generated dynamic code at the start/end of the script. (I have commented the parts that are dynamically changing on EVERY instance).PLEASE NOTE: Directly following this script is the start of a valid php script that I do not want to delete.
<?php
//{{65281980 - DYNAMIC!!
GLOBAL $alreadyxxx;
[code]...

I want to remove duplicate or multiple similar lines from multiple files. I.e. if I have four files file1.txt file2.txt file3.txt and file4.txt and would like to find and remove similar lines from all these files keeping only one line from these similar lines. I only that uniq can be used to remove similar lines from a sorted file.

I have a txt file with couple of comment lines:
Number of title = !num!
#line1
#line2
#line3
I wrote a script with "sed" to replace !num! in this file, which is very straightforward. However, based on the !num!, I want to remove the number of "#" based on the !num! value. Is there an easy way to do that with "sed"; otherwise, i will have to write a script to loop through the file.

I often use the rpl command to make changes to multiple html files at once. For example:
rpl -R '<br />' '<br /><br />' mydirectory However, I haven't been able to figure out how to change multiple lines. For example, let's say I want to change all occurrences of :
<br />
<br />
to:
<br />
I've tried
rpl -R '<br />
<br />' '<br />' mydirectory
but that didn't work. how to do this with rpl or some other way?

I want to be able to remove the first character of a line when I highlight multiple lines in gedit. Example:
%Example is
%Commented Code
%Uncomment using this shortcut
I would then highlight/select these lines, and remove the first character to make it look like this:
Example is
Commented Code
Uncomment using this shortcut
I'm pretty sure there is an actual shortcut for this. If there is another text editor on Linux that it would work in, it would be nice to know how to do it in that editor as well.

I run my own DNS servers and host my own domains. I'd like to host a few subdomains of one of my domains on a server with a dynamic IP. Is there a way to do this? I *believe* that I can host one subdomain by using a CNAME record and a dynamic DNS service.
[code]....
How can I host more than one subdomain on a server with a dynamic IP address?

I need to find a string in a file ... then delete the line it is on, as well as the next 6 lines. Or, delete the line the string is on and all subsequent lines until the search finds the character "["
example:
filename = test.txt
contents:
[foo]
test>test
test>test
test>test
[Code]....
so, in this example. I'd like to search the file for string 'foo' and delete all lines from that line until [bar] (not deleting the line with [bar])

I am trying to replace a string (url) in 100s of files located in different directories. I found the sed command but cannoy get it to work. First I locate the files that have the string in them:
Code:
grep -ilr 'url' *
this works correctly and displayed the location of the files that have the string:
Code:
1/index.php
2/index.php
Now I need to replace the string so I combined it with sed:

eed to make a script to append a line to the bottom of multiple files (only certain files, but 100's spread over directories).Doing a find replace inside multiple files is easy, I use the followingfind /base/dir -name "*.txt" -exec perl -pi -w -e 's/FIND/REPLACE/g;' {} ;So I tried doing the followingfind /base/dir -name "*.txt" -exec echo "Append this" >> {} ;However this just appends all the text into a file called "{}". Whereas {} should be replaced with each file that's found.

I've been trying to sort this out for several hours and I?m totally lost? I?ve been searching around, but haven?t found the solution to my problem. I have a directory with 100 files. I need to copy 10 lines of each files (let?s say from line 45 to 55) into one unique file. So I guess I could use sed ?w, but I didn?t manage to write the right script. I also tried using a loop to create 100 different files, each one with the 10 lines) to concatenate them later on. But I only got 1 file, not 100.

After hours (literally) of searching the web and reading man pages, I think I've come up with the following:Code:find . -exec grep 'path/to/file' -print | xargs -0 -I new_path mv {this is where I get confused}So my code above is incomplete, obviously. In order to finish replacing the string, I need to mv the new file into the old file's spot. How do I do this, by incorporating it into my line of code?

I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)

A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1,
parameter2,
parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually

I have been experiencing a problem where the screen loads and after initial first few lines breaks up into multiple repetitions of lines. Reloading helps but has to be repeated when pageing down. Mail is no problem; it is supplied by my network provider. OS is openSUSE 11.2 which I update when advised. Below is a sample from the error console:

I have a directory (Linux user) with a number of files which contain an added [!] to the end of each file name so that each file reads out as:
foo something [!].zip
bar something [!].zip
helloworld [!].zip
etc.
What is the quickest way to batch rename these to remove the ending [!] character combination from these file names?

I was doing some data recovery with Photorec and by the time I was done I have over 700 folders (recup_dir.).The only solution I was able to apply was the one posted by pljvaldez on this site dated 04-09-08, 09:01 AM. After doing the same thing for at least 70 times I decided to ask, so, is there anyone that knows how to delete multiple folders at the same time.

I'm a linux user, but definitely no expert writing a linux or awk script which can concatenate a default string to each line in a file. For example, I would like add "This is the end" to all lines in a certain file, so that after running the script the file would look like:
This is line 1 This is the end
This is line 2 This is the end
Some text on line 3 This is the end
