Fedora :: Delete Character MS-DOS Text Files On System?
Aug 17, 2011
We had seen some time ago, various tricks to remove the character MS-DOS text files on Linux. Here is a new trick to do this directly from the vim editor.
to convert a file opened with vim in UNIX format, simply use the following command code...
Through various Windows reinstalls and switches within Linux distros, I have a massive amount of duplication within my music archive (on the order of 7+ dupes of each file). Now, I found a lovely program called "fdupes" and was able to build a list of all the duplicate files, and I'm trying to use "xargs" to remove then. However, when I try and run the command "xargs -0 --arg-file="dupes.txt" rm" or "xargs -0 rm < "dupes.txt"" it give me the following error: "xargs: argument line too long".
how perhaps a different way of accomplishing the same thing?
When I boot up my Ubuntu system I get the following error message:Install Problem The configuration defaults for Gnome Power Management have been installed incorrectlyI found the following posting and this describes what also happesystemhttps://answers.launchpad.net/ubuntu...uestion/111256I've created a recovery disk by using a memory stick from which I can boot. I can mount the old filesystem (HD). When I navigate, with the file browser, into one of the folder on the the HD and try to delete messages I get the following error message - 'Error removing file: Permission denied'.I guess I need to log / tell those files the root password from the system installation as per the version on the HD. But how do I do this?
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
I have an external hdd which is formatted with fat for use by both on linux and windows. The issue is that I can't delete some of the files I have which show up with size 0. Also, the modification timestamp (as detected by Krusader, the file manager I am using) is 1935. How can I delete these kind of files without affecting the running fs?
I had some bad luck today when I was trying to fix an account that had trouble with FTP. I decided to remove the user and add him again and reset all configuration. Anyhow, to make things short, I accidently typed rm /* -R -f and without looking hit the enter button, as soon as I realised what I wrote I hit ctrl+c. Too bad the /bin/ folder was gone by this time and standard commands like ls didn't execute anymore.
My question is if there is any way to recover these files by a system repair or something? The server is used to host a heavy loaded site which can't afford any downtime, and silly me didn't make a backup of the whole HDD, just the important folders (not the system files).
Currently I don't have the balls to restart the server as I know this will probably turn into a dissaster. I also don't have straight access to this server since it is located in a datacenter (I can go there if absolutely necessary but I rather don't).
I have some very confidental files on my computer that I store such as credit reports, and other things. I always encrypt them with GPG, but there still is that original non-encrypted file left that needs to be deleted. I looked into tools like wipe, and shred but they all say that it really doesn't help on journaling filesystems directly on their man page.
I am not asking how to wipe the whole drive with dd or anything, but I am simply asking if there is a tool that'll delete a single file securely.
I use Ubuntu 9.04 exclusively on my own machines, but I have a couple of flash drives that got infected by some corrupt windows executable (*.exe) files, probably by somebody's trojan (they are Cruzer 4GB so came with installed fancy programs that I dont need but didnt remove and Windows keeps installing unwanted ini files and other trash every time I use them in somebody elses machine or in an internet cafe). I deleted quite a few files, but some are stubborn. $ sudo chmod +w-X doesnt seem to work. How do I unprotect and remove them? The filesystem is vFAT.
I suspect the files were created by some kind of a trojan as my work requires my flash to be pretty promiscuous. When I 've backed up all the good files I need, I'd be happy to reformat the flash drives as straight vanilla data storage and retrieval, provided I can still use them on a variety of machines running MS windows as well as on my Linux machines. Any guidance on reformatting?
I have the cowon iAudio7 music player with vfat file system and increasingly running into permission problems when I try to delete files. Unsurprisingly I am now running out of space. I am figuring if I could somehow mount it onto a folder in my home partition I will have full permissions. The problem is the drives name which is exactly with space: So even if try to delete files in the terminal I don't know how to cd into:
Code: /media/I AUDIO7 note the space between I & AUDIO7.
Some pdf readers for windows allow you to highlight and type notes into PDF files. The pdf readers that I've seen for Linux only allow you to read pdfs. Are there any that allow you to highlight text and add notes?
I am running some Pcap files through editcap and then tshark. I am running fedora 11. This will create a couple of thousand text files all numbered sequentially 1-x. How can I copy these files across a network(I connect using putty) or how can I copy them onto an external HD so that when I view them on the windows machine they have the right formatting (Windows know to open them with wordpad/notepad) basically that windows knows that they are text?
I have downloaded both versions of Fedora 11 (Gnome and KDE) to iso files on my hard disk - in Windows XP. I then tried the verification procedure advised in [URL]... section 3.1. I have successfully installed and run hashcalc, with the SHA1 option, and got the following results:
- for the Gnome version : 795b52b3c7b16eba6f2cae055ec894d8648d8095 - for the KDE version : 38ef6c97e29803add28d40add05aa025b6f4c92b.
But I can't find any SHA1SUM files to give me the correct character sequences against which to compare the said results.
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
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 want to be able to find the lines that matches my input and change the N to a Y, but only for the lines that matches the name and not any other N's My problem is the line does not always contain a P as it can be a D as well so my matching did not work. If my script issues the name $1=triva the lines will change to:
I have the following code so far but as you can see it does not change the D's
sed -i 's/trivia:P:Y/trivia:P:N/g' servers.txt
*** UPDATE ***
should I be using a method as follows? I am still stuck on the changing all instances though.
$1=server sed -i 's/$server1:P:Y/$server:P:N/g' server.txt sed -i 's/$server1:D:Y/$server:D:N/g' server.txt
The lines beginning with greater-than symbols are the sequence descriptors and the lines immediately after each descriptor with A-Z characters, dashes, and question marks are the aligned DNA sequences. The sequences are always the same length within a file and never span/wrap across more than one line.I am trying to write a script to remove positions in the sequences that are only represented by a -, X, ?, or N (these represent gaps or missing data). Also, if there is exactly one non-gap/missing character in a position it is also useless (there is nothing to compare it to) so I would like to remove those positions as well.
Position 5 (from the left) was removed because it was all gap/missing characters. Position 9 was removed because only one character was a non-gap/missing character. Position 10 was retained because there were 2 non-gap/missing characters.I'm really not sure where to start here. My first concern is I can't figure out how to tell awk to treat each character in lines not containing a greater-than symbol as a separate field. After that, I'm thinking I should use set up a counter to count the number of lines with gap/missing characters comparing that to the total number of lines not containing greater-than signs?
I need a lightweight GUI text editor on my Ubuntu Lucid system which lets me specify a Unicode code point (e.g. U+1234), and inserts that character to a UTF-8 text document. I know that gedit can't do it (not even with the Character Map plugin).
I'm not interested in solutions involving any kind of emacs or vi. I'm also not interested in text editors running in the terminal (such as joe, which has this functionality). I need the absolute simplest, smallest and fastest plain text editor for Linux which lets me type a few letters, insert a few characters by their code, type some more letters, and then save the .txt file as UTF-8-encoded.
I want to use SED to do the following: In a text file replace any occurrences of the three character string ZZZ with a quotation mark "and. replace all occurrences of a comma with a semi-colon. It is the S/ / / command which is stumping me on the first issue...inparticular how to get the replace string to be quote.
