General :: Used DD Command With No Options
Dec 31, 2010
I was in the CLI experimenting with lynx and then I thought let's see what this dd thing can do and usually when I run commands without parameters just gives me an brief idea about what can I use. With dd it just hangs on there like it would be doing something ...
I immediately quit that terminal and then I couldn't mount my ntfs big important lifesaver partition. I rebooted and now I can. I just want to ask what damage could dd make if run without any parameters. I don't have any external backup medium.

I'm having a hard time trying to print documents to PDF via cups-pdf at the command line and get all of the nice formatting options that the GUI print spooler dialogs provide. I know how to do "lpr -P Generic-CUPS-PDF-Printer filename" to get a general file printed to a PDF, but this method clearly is missing all of the nice formattingptions that get passed when using a GUI print spooler (margins, fonts, dpi, paper size, etc..). I tried to use ps to capture whatever command is being sent by the spooler but couldn't figure it out, since I'm not really sure what commands get called by the spooler

(1) I'm wondering if there is a way to have abcde play the songs while it is encoding? I understand that this would be a lot slower.
(2) Is it possible to have abcde start playing right after it finishes ripping the first track and then have it add on the other tracks to the playlist as it rips them.
Is there anyway to do one or both of these from the command line or with abcde's built-in options?

I have a working fstab entry:
Quote:
/dev/sdc1 /media/sdc vfat rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,s hortname=mixed,dmask=0077,utf8=1,flush 0 0
But how do I mount the sdc drive with those options from the command-line without restarting? I've tried to do so with 'mount' utility, but had no luck.

I have an executable with input options, like so:
Code:
./executable -n 42 -s 42
I've added gcov to the makefiles (compiling with --coverage, -fprofile-arcs, and -ftest-coverage, and linking with -lgcov). It builds fine and creates executable.gcno.
When I try to run gcov, gcov things the options belong to it:
Code:
$ gcov ./executable -n 42 -s 42
gcov: invalid option -- 's'
Usage: gcov [OPTION]... SOURCEFILE...
When I use quotes this happens:
Code:
$ gcov './executable -n 42 -s 42'
executable -n 42 -s 42.gcno:cannot open graph file
The command line options must remain. How can I get gcov to generate the same .gcno file it later looks for?

So I have the burned ubuntu CD, and I'm attempting to install it on a system that has one HDD with XP/Vista on it, and another that is completely formatted and unpartitioned. However, when I boot to the ubuntu CD, I can use the menus from the bottom, and select the language when initially prompted, but I can't select any of the menu options except for boot from first hard drive.

I know that 'man gfortran' will get me the manual page for gfortran, but how do I lookup only the bit I want, which is '-Wall'? I can't find anything in the manual page for man.I could use 'man gfortran | grep -Wall' but that would return just a single line and not the whole paragraph.

I'm currently building a Raid5 Volume Set (HW-Controller, 3 disks). After some diskussion I decided to don't use a partition since I don't see any disadvatages writing the filesystem (ext4) directly onto the device.
Because I plan to expand the volume set with 2 more hard disk drives, respectively the filesystem, to get the complete disk space available I read the ext4 manual. There is an extended Option called max-online-resize with the description:
Well, although I've searched for more details on the internet I can't find any. Primary in which case is it usefull to set this value because later resizing should be possible without to set this value. Maybe it accelerates the resizing process?
Next, I also plan to use the options stride=stride-size and stripe-width=stripe-width. Is it advisable to set these values for the final volume set (Raid5 with 5 drives) or do I have to set it for the first volume set (Raid5 with 3 drives) and then changing these values during the later resize process for the filesystem? (I personally prefer the first method).

I have just purchased a 1 TB external hard disk to be used for backups. The backups will be performed with rsync and since I don't really care about accessing the data from other operating systems, I think I'll use ext3 on the partition. I'll just be backing up my home directory and probably /etc as well. In my home directory, I have a small number of files that are several GB, but most are tens of MB in size or less.
I'm just wondering if there are any special options I should pass when I create the filesystem with mkfs.ext3.

I want to know how to setup SUDO, here is exactly what I mean. I have Zorin which is a ubuntu build, I have it upgraded to the newest 11.04 - My main user is Hevithan and I have a seperate user account called GUEST for anyone who wants to use my laptop. Hevithan I guess was setup to have max root powers cause when I type sudo in terminal with no option specified it returns:
Code:
Hevithan has access to
all (ALL)
all (ALL)
all (ALL)
I want to setup my GUEST account to have virtually no powers (no installing files or programs, no using Ubuntu software,no altercation of anything on the Hevithan account,etc), But I want anyone using it to be able to fix things using the terminal if need be (such as my cousins or girlfriend). To what things should they be allowed to do to able to fix but not alter? And if I want them to not be able to install programs or download porn (video at least) and $#!+, but still get things like MP3s and wallpaper images is that possible?

I used the usual 'mkfs.xfs -l size=128m,lazy-count=1 /dev/sdX' at creation. After that, I would like to use custom mount options like: This goes instead of the "defaults" part in /etc/fstab
noatime,nobarrier,logbsize=256k,logbufs=8,biosize=16
I receive the following error at boot: INVALID log iosize 4 [not 12-30] << No one used iosize 4... what does it mean? it is connected to the options..but which one? (At the minute I'm usig it with: noatime,nobarrier).
