Ubuntu :: Rescuing Files By Command Line Only?
Jan 4, 2011
I have a laptop with Ubuntu 10.04 which appears to be completely wrecked. Even in recovery mode I can't get any GUI. The only access I can get is via command line, which with my limited knowledge of cd and ls commands shows me that the home directory is OK and all the data files present.
How can I get the data files off this machine, eg by copying them to a usb stick, or maybe by copying them to the Windows partition (which still works OK)?

Is there a method at the command line to copy files from one location to another and retain the source files group and user?I'm migrating some MySQL files from one machine to another.I want to back-up the original files in the directory presently. They have owner:group of mysql, some have owner:group root:mysql and so on. To copy them under cli or Nautilus everything changes to root for I execute sudo cp or gksudo nautilus and copy via gui.
Since it is MySQL data I could simply do a dump of the database and restore it on the other machine. But there's about 20 db's and I want to do this via a copy for it will be faster - at least that is what I think.

I had a great system going with a bash script to update all of my mp3 files' genre tags. Now that my music collection is ogg, id3v2 doesn't work.
Can anyone recommend a command line tool to edit tags for ogg files please?

how to download or upload files to a Debian machine using only the command line. I well aware of how to do it in GNOME, but seeing as how this is for a web server, I won't be using GNOME. I have a zip file on my personal machine that contains the website files that need to go on the Debian machine that is to be the web server, but I have no how to get it to that Debian machine without GNOME.

Some time ago I installed LAMP in my server, but now I need to execute .php files from the command-line (in order to execute some manteinance scripts for mediawiki). Seems that the PHP files running in the server are run thru some kind of "module" in apache2. Can I tell apache2 to run a .php file in command-line mode using that php module? Or should I install a fresh copy of php-5? Won't that interfere with apache or mangle the system?

command line, I have a server for work that I ssh into and I need to be able to find multiple files (they have the leading text just the date identifier changes) and then zip the files (with bzip) them and then finally scp(Secure copy) them to another server.
These files are always in the same directory and this is a daily task and just want to make into a script that I run once I am logged into the remote server.

Is there a way to remove duplicate files from a specific folder through SSH? I've uploaded a lot of flash games on my server and I can see in the Webmin's file manager that I have many duplicates. Their names are different, of course.

I liked the idea of the "cosmos" screensaver/desktop, but wanted to add my own pictures to the application. I navigated to /usr/share/backgrounds/cosmos and tried to drag and drop. I quickly found that I did not have permission to do this.
I googled my problem and found some command line tutorials telling me to sudo cp. My problem is that I have about 30 pics that I want to move in there, and I don't think I can just move the directory, they have to be in that folder as the pictures themselves.
I don't really feel like typing the cp line multiple times with multiple randomly named image files.
Is there a way to have the command line cp all of my files from one directory to another?

I'm looking for a solution for the following simple problem. I have two files, fileA and fileB. Each file contains only one word per line, and they contain exactly the same number of lines. I would like to create a new file called fileAB, where the i-th line contains the i-th line of fileA, a Tab separator character, and then the i-th line of fileB. I know how to do it in Python or other scripting languages, but it would be nice to have a bash one-liner for that. Is it possible to do this in bash or any other Unix shell, using the tools that are usually available on the command line (e.g., sed, awk and such)?

I have just accidently deleted /usr/lib as root, how do I restore it from the trash can from command line? Seeing as how no programs will now run. I can't seem to find /root/.Trash, no such folder seems to exist ,or did I just royally screw myself?
Edit:
First off where is the Trash folder for root in Fedora 11 I have googled and looked everywhere I can't get a straight answer. It is not in /root/.Trash for one.

I have huge text files with two fields, the first is a string the second is an integer. The files are sorted by the first field. What I'd like to get in the output is one line per unique string and the sum of the numbers for the identical strings. Some strings appear only once while other appear multiple times. Given the sample data below, for the string glehnia I'd like to get 10+22=32 in the result. how to do this either with gnuwin32 command line tools or in linux shell?

I have a large amount of log files that I need to remove sensitive data from. The sensitive data is provided to me in a text file and is prone to change. I had hoped to do the equivalent of this:

The commented out egrep works fine, the sed doesn't. Am I right to use sed for this? Or is there a more apt route to take?

I have an Acer Aspire 5100 with Ubuntu 10.04 running. Recently I loaded from a storage drive all of my music library which happens to be in its orignal wav format. I was going to convert it to mp3 using lame or some other program. I worked with the files using the command line with some success. The files were there when I did this. No problem. I came back to the computer after several days absence and when I got to a commandline I entered "ls -l" no files. Yes I went to the right directory. I logged in as Root no help. The files are not there according to the command line as far as I can tell.Using Gnome the files are available and playable via the desktop. Are the files there or not?

When I move files with the mv command, it simply waits until the file has moved and then the command prompt appears again. This is fine, but there are two things which are rather annoyingThere is no progress bar: When moving really large files, you have no idea how long the move is going to take. Is there possible to produce a progress bar to show how much has finished? You can't do anything while you're moving: You can't use the command prompt while you're moving the file/files. I'm currently not using a Linux computer (I'm at school) but maybe it's possible to write mv <file> <location> &, I just thought of that just now. Is it maybe possible to use another program than mv to move you files?

I'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.
Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier.
If I was searching for a single word, I can see ways to do this.
If I paste the code I'm searching for into a text file, is there a way to:
find (contents of oldstring.txt) and replace with (contents of newstring.txt)?

Lets say I have 20 files named FOOXX, where XX is the number of the file, eg 01, 02 etc. At the moment, if I want to delete all files lower than the number 10, this is easy and I just use a wildcard, eg rm FOO0* However, if I want to delete specific files ina range, eg 13-15, this becomes more difficult. rm FPP[13-15] does not work, and asks me if I wish to delete all files. Likewse rm FOO1[3-5] wishes to delete all files that begin with FOO1 So, what is the best way to delete ranges of files like this? I have tried with both bash and zsh, and I don't think they differ so much for such a basic task?
