Ubuntu :: Deleting File With '' In The Name
May 27, 2011
I tried running a back-up/restore script in a WordPress install to migrate from one server to another... long story made short, I ended up doing it manually and all is well on that front
The one remnant from that botched script is that it tried creating a directory 'wp-backup' and then a file inside that directory - but it tried using '' instead of '/'. So what it created was a file named 'wp-backupindex.php' with a file size of 0 bytes.
The problem is thus: I can't change the permissions nor delete the file, because of the invalid file name. I don't have direct shell access (that cost *extra*, of course) and every time I try with the web-based file manager (Quixplorer) it sees it as 'wp-backupindex.php', as though the '' is acting as an escape sequence in the file name. Same thing in FileZilla, I can't do anything to the file without it complaining about the invalid file name.
how to ixnay this one file given the limitations above (no shell access) short of calling and bugging tech support to delete the file for me?

I am using Ubuntu 10.10 and 10.04 on two different computers.I have the same problem with both .... when I delete a file on my hard drive or a removable drive I dont get the space back even after I empty the trash.The file is gone and deleted but its as if its only hidden from me seeing it and still sitting on my drive.For example when I have files on a thumb drive and I delete them and try and put new files on there it will tell me I dont have enough disk space even though all files have been deleted, the only way for me to get the disk space back is to format the drive.I have now realized I have the same problem with my hard drives, I delete files but I dont get any space back, eventually I will have a full hard drive but no files on there

This has happened twice to me. I'm editing a filename on the desktop, for example, I have a part of the name highlighted and press delete. Inadvertently, I press delete again, but with nothing highlighted. The file is deleted, but is not added to the recycle bin (possible bug).
I believe that is what is happening. I cannot seem to recreate it purposefully on my work computer --I had done this at home this morning while sans-coffee.
Is there a way to recover the files?

rm [non-empty directory's name] -r
....and not....
rmdir [non-empty directory's name]-i
..or..
rmdir [non-empty directory's name} -ir
backround:
I just downloaded and innstalled 11.2 about 6 weeks ago, and Have updated several times since... I was very frustrated and found that I did in fact have the proper pernissions to delete this directory. I checked multiple forums for much longer than I would like to admit, and they kept telling me to use (in the end) the same commands.....I finally stumbled upon a forum that again told me to use rm [nonempty directory's name] ...and viola
my /bash can't be outdated can it

Currently, I'm working on personal project. and I'm kinda stuck. What I want to do is that open a file, and edit that file (deleting unwanted characters). The problem arises after I deleted unwanted characters, the file still has the same length of the original one. Let's assume that we have a file with "1234" in it. I deleted "3" ( I overwrite "\0" ) so now when I check the file, it's 124. But when I check the length, the both have the same size as 4
Here is an example source code
int length, length2;
num = open("a.dat", 2)
length = lseek(num, 0, 2); // Initial length
lseek(num, 2, 0); // editing
write(num, "\0", 1);
length2 = lseek(num, 0, 2); // Final length
close(num);
When I print those values those are exactly the same. Length2 should be one less than length, but the both are 4. What's wrong in m code? Am I supposed to use different character rather than "\0"?

I have two text file named 1.txt & 2.txt.
1. txt contains 5 laks of mobile number.
2. txt has 60 laks of mob no.
Situation is that I want to find and delete numbers in 2.txt which already in 1.txt. Any perl or bash script or any other way to get the work done.
I tried the following:
#! /bin/bash
IFS=$'
' for NAME in $(cat one.txt)
do sed -ie "|^$NAME$|d" two.txt done
echo "***DONE***"
It works well with smaller file but it take very very long time even processing 10 thousand numbers.

In my command prompt I did:
Code:
sed 's/://' mytextfile > newtextfile
But it only deleted the first instance of : in each line when some lines have multiple : appearing in each one. How can I delete all the : from the entire file?

I 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 have an issue with apt-get that has been bugging me, namely that it tries to delete kernels I did not specify for deletion.
This is an issue that has been present over at least the last three releases and is present for both 32bit and 64bit, so it might actually be a feature and not a bug, however I can't see it's usefulness.
When I use the command:
Code:
sudo apt-get remove --purge 2.6.32-21*
It not only tries to remove the kernel 2.6.32.21 but gives me the following output:
Code:
sudo apt-get remove --purge 2.6.32-22*
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting linux-headers-lbm-2.6.32-24-generic for regex '2.6.32-22*'
Note, selecting linux-headers-2.6.32-21-preempt for regex '2.6.32-22*'
[Code]....
When I go through with this command to remove the oldest kernel on the system, it will actually delete all kernels present on my PC (as I painfully learned when I first tried it). Why is that the case? Wouldn't it make more sense to only remove the kernel 2.6.32.22?

I'm pretty new to Ubuntu and it might not be possible to do what I want to do here. First I'll explain the situation. Throught trying to tidy up my mp3 collection usign various pieces of software I now have a folder structure that I want (My MusicArtistalbum rack), However, in the process, I have been left with lots of other folders - these have had the mp3's removed but they contain other files (artwork, playlists, .nfo files - that kind of thing).
What I'm looking for is either a premade solution or help with a script to do the following : Check all folders in my music folder, if the folder doesn't contain any mp3's then check the subfolders, if none of them contain mp3's then delete the main folder (regardless of what otehr files are within it).
It seems like I should be able to do this - but not sure how. Incidentally, I have backed up my music folder to an external disk - so I can't do any lasting damage

Is there any way to install ubuntu on a drive without deleting the current data on it:
I have a software raid array set up and it has a few folders in it like /rtorrent, /cod4, but nothing that would conflict with a new ubuntu install.
And its formatted as ext3
Is there any way I can install Ubuntu Server 9.10 onto that raid array keeping it INTACT as a raid array AND preserving the data on it?
And is it easy to boot from a software RAID array?

I've followed some instructions on installing a new hard drive on Ubuntu ("Installing a New Hard Drive" and "HOWTO move /home to a new hard drive") and I've now successfully got my new drive working with /home. Everything looks to be in perfect working order.Now I'm wondering how to delete my original /home folder. Running "df -h" still shows 97% usage on my / partition and I'd like to clear out the old /home to free up all that space. I just don't know where these files are now is all.

I was on line and viewed a Picassa slide show. I went to F11 for the full screen and after I closed Picassa,my Firefox browser had been reset,creating all kinds of issues,taking out my status bar,making it impossible to access the three icons in the top right hand corner of the screen,and so forth.
When I removed and reinstalled Firefox from the Synaptic Package Manager,it did not give me the option of not saving the settings and the same issues pertained to the newly installed one.
Does anybody know the shell code to remove and reinstall the Firefox Browser unsullied,pristine,not saving the existing settings?(realizing I'll lose the bookmarks and have to set it up anew?)

I am a new UBUNTU user. I had installed OS in my computer in the order of XP, Win 7, and finally UBUNTU.With EasyBCD, I managed multi-booting order of XP and Win7. That is, after choosing Win7 or UBUNTU from GRUB, (If I chose Win 7) I should choose XP or Win 7 to boot.
Using UBUNTU, I think that I do not need XP, so I formatted the hard disk where XP was installed. However, after deleting XP, I can not boot Win7 from GRUB, although there is still

I accidentally hit the delete button on a folder. Luckily, it was still in the trash and I could restore it. However, I was wondering if there was a setting that could display an 'Are you sure?' question before deleting the folder in case this happens in the future again.

Ok so basically this isn't my harddrive but hear me out. It's a known issue but it only happened after him downloading stuff off priate bay. The harddrive is not detected on BIOS, so you can't boot through it, just the CD Drive is now detected. You can't use SAFE mode as it reverts to another issue, a black screen with a white cursor, no keyboard commands work.
No restoring disks will fix it nor master disks, it's literally a bad *** issue. Thou I can still load things via CD Drive so I used the Acronis Bootable Media and surely enough, it could anaylse data on the harddrives. I thought maybe i'll try PE Bart but once again, loads up to Black screen with White Cursor. So I put in Ubuntu and yes, I can get on the GUI, but I can't install the operating system.
There would always been an issue. something about in/out whilst installing but as long a I can use the tools, then we go onto Disk Utility. When I try to format, the Error Message apprears stating : Eroor creating File System: helped exited with error code 1: Error calling fsync(2) on /dev/sda2: Input/Output error. This would be the same error i would get via installing and I would have to ignore and eventually whilst installing, from being complete on the right hand side, it would say ERROR or ABORTED after 70,000.

I did a "backup" of my .wine folder by copying it to my network attached storage drive. Now, that folder thinks it has about 200gb of data! Specifically, it's the .wine/dosdevices folder. I didn't grasp that Wine had created some kind of hard links to my ~ folder on my Ubuntu box. Since that folder is clearly recursively linking to all my files, I'm afraid to just delete it. I did delete one file within it as a test and, sure enough, the original file back on my Ubuntu box disappeared!how can I delete the .wine "backup" folder I created on my NAS without deleting all the original files?

i recently removed the Ubuntu partition in Windows 7. When I try to reboot I am faced with the the grub rescue error where it says no such partition.. I have tried booting Windows 7 from disc and I have even went into my BIOS and it says CD-ROM boot priority.. boot ready then says the grub rescue error again, stating that there is no such partition.
This is really annoying as all the tutorials on the internet say insert Windows 7 then use the recovery tools but I can't even boot any operating system. I have set the BIOS to boot from my CD drive..
