Programming :: Search For A Word In A File And Then Comment It Or Delete It?
Aug 9, 2009
I want to know that how can i search for a word in a file and then comment it or delete it. I know this command works.
sed 's/word/#word/'g inputfile > outputfile
But the lines in my input file are as under:
zone "abc.com" { ---- This line can be comment
type master; ----- This line repeat again and again in the file
file "abc.txt";
allow-query { any; }; -This line repeat again and again in the file
};
Want to search for ~ and delete it as well as to append the entire line to the above line. For Ex:
1111xxxx date Sandy area is ~around this area.3222xxx date There seems to ~left side of map, the colours are accurate (showing green areas)Even if I ~zoom in, the green parks, xxx3258 date The dammed up ~away, the "other" body of water varies ~blackNatural gas leaching.
IT MUST LOOK LIKE:

I have been looking around for a, "start new thread" button but cant seem to find it (which is my first question). My real question is, how do I delete a word in a vim file from the editor command? What I want to do is go to a specific line (36) and delete 3 words after my cursor
i.e :36 | 3dw
error: "3dw" is not a command. Ive tried ":d" this deletes teh whole line which is not what I want.
I need a command to find the all files which filename contains the text "SomeText" and to delete that files!From /home/movie/wp-content/uploads/this folder I have lots of files and folders .Also I need that for folders and subfolders who contains some text in folder name "someTextInFolderName"
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
Well, I am facing one issue:How can i read two files word by word at a time using any loop as i need word by word comparision in shell script?Please let me know pseudo code.
As you can see i would like the output file to be just the dogs, not the otehr information. But because the information is mixed up how can i extract only the dogs? (i cant do and awk '{print }' because the dogs are found in colounm 2 or 3 or sometimes even 4.
I am pretty new to bash scripting...I am trying to write a script that will take an input and read it word for word and then DO something with it like echo. I have been able to find how to read word for word from a file but I don't know how to do it with input.
I was looking for something like
Code:
exit 0 The input would be A-Z a-z 0-9 and have a single space between each word.
I have grepped a log file to obtain every line that contains a word (let's call it 'blah'). I now want to only display a list of entries within that search result that feature the word 'host' anywhere in the line, and I also want to display the single word *after* 'host' (up until the next space). So, the end result will look like this:
I am using ascript for general users to back up usb drives to lto4 tapes.. I wish to ahve some error checking to check IF is there is a tape in the tape drive to check for the tape:
if i do a sudo mt -f /dev/st0 status i will get back a mt: /dev/st0: rmtioctl failed: Input/output error if there is no tape in the drive or sudo mt -f /dev/st0 status

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?
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.
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.
I have a lot of files in the server with name like checkfile.jsp and in the file has two or three lines with an ip address xxx.xxx.xxx in it. I wish to know if there any command to grep for the i p address and remove itin file but keep the " ", eg "xxx.xxx.xxx"
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
im tryin to make a tool in visual C++ which will take an input string through a text box,then it will compare tht string with a text file containing data and display the matched results in list box.
I'm wanting to mod some PHP files across a hierarchy and thought I'd drive it with find + grep + xargs
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:
Code: 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 so I thought I'd try using Code:
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?
As indicated in the subject, I want to search a text. If the text is present I want to replace it. But if the text is not present, I want to insert it after first line and before last line.
for example we search a file for a certain keyword..is there any application available which will enable us to search for a single keyword in all the files within the folder ?i want to search for a keyword in about 1000 files..if i do it manually it will take loads of time..
