I've a big text, and I would like to delete several lines in vim. I was thinking in doing that with marks, but I can't do it. Below it's an example text and I want to delete from <FROM HERE> to <TO HERE>. How can I do that?

I am facing some problem regarding deletion of a line from a text file. The file consists of the lines of type which consists of more than 6 occurrences of : character in it. The line should be deleted completely and the line next to it must be shifted up.

View 14 Replies View RelatedI have a file which contains milion of records. It contains 12 columns seperated by "||" (delimeter).
First two fields contain first name and last name of a person. Now my requirement is to delete all those records from this file for which:
First two fields does not contain any alphabet.
For e.g i have below mentioned records in file:
gaurav||gandhi||123||456||789
#a%bcd||123abc||89|90||91
12345||@@@||89||123||234
***||!!!!||98||76||90
Now, last two lines should be removed from this file since first two fields does not contain any alphabet for these two records.
I have a very, very large log file (360MB) that I'm trying to thin out. As it turns out the majority of this file has entries that aren't necessary so I'm attempting to build a command that will strip these out. The following command works to display only the data that I do not want:
Code:
cat xml_results.log | grep -B 6 -A 5 "YYY ZZZ"
This displays exactly the data I want to delete from the file by displaying the expression and six lines above it and five lines below it. However I'm at a loss as to how to remove this data from the output and display everything else. I looked into the -v option with grep redirecting the output to a new file:
Code:
cat xml_results.log | grep -B 6 -A 5 -v "YYY ZZZ" > xml_filtered_results.log
However it doesn't work, the new file is the same size as the old one. What am I doing wrong? Is there a better method of doing this? I'm a bit out of my element since the method I'd normally use can't handle files of this size.
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.)

I have this massive table file with some data in it and I want to replace some lines that are wrong with the correct ones that are in another table file of the same format. The wrong lines are not all together in a block but randomly distributed so I need to make a loop checking if the line is in the other file and if it is, replace it.

View 12 Replies View RelatedJust wondering, what happens when you delete every single file on a running Linux system?
# rm -rf /
I am a non-root user, and have made a directory into which other users in my group can write. The directory is setgid, so files and directories within it have the same group.I can delete files placed into this directory, but if a user creates a subdirectory with files in it, I can't seem to delete those. Is there something special I can do (other than, say, bothering the user in question or the sysadmin about it) to get rid of this subdirectory?
EDIT: Inevitably, of course, someone asks "why?"The shared folder in question is a mercurial repository. We can't use a shared-account ssh-key-based server for this like mercurial-server, and we can't just host it externally for various reasons. But that part works fine.We use Redmine for project management, but it does not yet read the repo index for file contents - it reads the working directory. So the working directory must be kept up-to-datecrontab has been disabled by the sysadmin, so that's out. So I naïvely put a changeset hook in the shared repo that performed an "hg update". This seemed to work fine initially, until, of course, someone pushed a commit with a new directory. While I had vague thoughts of trying to make a setuid script for the hook, I'll probably just consider safer avenues.
I have a laptop that I was dual booting with Windows 7 and Ubuntu. I used the MSFT disk manager to delete the partitions. I made sure my windows live cd was working, which it was, before doing this. But now, when I boot my computer, it won't run the cd. All I get is
error: no such partition. and then a command prompt: grub rescue>
I made sure my boot priority was set to boot from the CD first.

View 2 Replies View RelatedI have a large number of zip-archives which I would like to extract and then delete, keeping only the extracted files. The files are located in a number of directories and I issued the following command, hoping that it would solve my problem (which it didn't):
Code:find . -name "*.zip" -execdir unzip '{}' ; -deleteWhat happened was that find continued to extract the files as intended, but then it deletednot only the zip-archives but also the newly extracted files.it only affected a portion of the files that I had already backed up.I don't have enough space on my hard drive to extract all the files without simultaneously removing any data and I don't have the energy to go through all the directories one by one manually. Surely there must be a better way. Is there a way to fix the code snippet above so that it works as I intended or is there a better way of doing this?
