Software :: Delete Top Lines Of A Text File Until A Word Is Met?

Jul 7, 2011

I need to chop of the top 30ish lines of several log files until a line starting with "Initialization completed."The trouble is that it's not always the same amount of lines that need to be deleted, and they don't always contain the same information, which is why I would need to delete everything priorhe line starting with "Initialization completed."Right now I have a little script I wrote based on looping each file through several "grep -v" commands with each known pattern of lines I want to ignore, but it is tedious and I have to inspect each file afterwards to make sure nothing is left from above "Initialization completed

Programming :: Insert A Comment In Html File Based On Its Contents?

Jun 10, 2010

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.

General :: Unix - 'man' Command: Search For A Word/phrase And Cycle Through?

Jun 29, 2011

When looking for a certain word or phrase in the man page of linux command, one can type '/' followed by the word/phrase to search for it. What I'd like to be able to do is to search for the next occurrence of the word/phrase without having to type it out again. Kinda like when you use 'ctrl+f' in a browser to search for a word, and then press 'enter' to find the next occurrence of that word.If this is possible to do, how do I do it?

Programming :: Search And Replace In A Binary File?

Aug 11, 2010

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.

Programming :: C++ Character Search In Text File?

Jun 23, 2011

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>

Programming :: Scipting Assistance To Search For Servlets In Xml File?

Jul 18, 2011

We're migrating from Tomcat on Linux to Glassfish on Windows and I'm trying to make it easier to find the servlets that we don't currently have implicitly mapped in the Tomcat web.xml files for contexts. What I've done is copy all our contexts to a temp directory and written a script so that I can loop through each context, find the files that are not mapped inside a package then check if the java file is a servlet or not. From there I store each java file that matches, strip off the extension and then search in the context web.xml for a match then output to the screen.

The problem that I'm running into is that I know there are class files that should be returned and yet they are not being displayed. I'm not a Linux guy, so I'm just looking for a little help to see if I'm missing something obvious. I've attached the code for the script below.

Code:
# for all contexts
for context in `ls "/var/tomcat/temp/script/" | grep -v servletmap.sh`
do
echo $context
# for all java files without a package

Programming :: Multi File Recursive Folder Search And Replace?

I built up a command line which I was confident would do the job, but now can't save the results.

First I tried this:

find . -name *.php | xargs grep serialize | cut -d: -f1| sort -u | xargs sed -i s/serialize/serialise/g
but that didn't work:
Code:
sed: illegal option -- i

Ubuntu :: Highlight Then Delete ; Misses First Letter In A Word / Resolve This?

Jun 26, 2011

When I highlight a word then delete it, the word is erased as expected. But when I highlight a word and begin typing a word to replace it (instead of deleting or hitting backspace), the first letter of the unwanted word does not erase... so I am required to watch my text very closely when editing.

For example: I'll type the word "fungus" and then highlight it and type the replacement word "mold" and when I look at the text, the word is "fmold". Am I the only one with this odd situation?
