I am having trouble keeping the name together and the phone number together, I think due to the white space. I have tried "" and '' it doesn't seem to matter. So it may be my syntax? and does it matter how long the first and last names are.
I have successfully gotten my Canon MX300 Printer to work with CUPS. The printer works great, but for some reason it prints out white lines incredibly slow. The printer acts as if it is printing out actual text, e.g. if I have half a page of empty space, it prints it line by line for some reason... Anyone know what may cause this? I know that CUPS is not ideal with all printers, but it did not do this at first actually.
Some context: I'm calling some functions from within a C program and want to measure how long they take to execute. I've done this successfully, calling printf to print the results to the screen. This is reasonably fast. Ideally I'd like these to be dumped to a file, but fprintf presumably has some overhead since it writes to disk? Unless the data is buffered by the kernel and flushed later? What kind of delay can I expect before fprintf returns?
If I redirect the stdout to a file when I instantiate the binary as a process, will calls to printf also experience any overhead from redirection to a file? My aim here is to capture all data in a file, with the minimal amount of coding and effort, but with minimal impact in terms of time overheads for printf calls.
I scanned a document with xsane and saved it as a pdf, the pdf shows up great but there is extra white space at the bottom of the document. how do i get rid of the white space and make the document the actual real legal size?
Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
2. If system have only 256MB of memory (embedded system) and suppose Kernel Modules eat away all the memory during boot. User space will be left will no memory. Is this case possible?
I need files to be <= 5GB to put on S3. Right now I have an ugly tar / gzip / cut before upload, then cat / zcat / tar on download, but it's really ugly - and nearly every archiver should support archive splitting right? What's the best way?
I am facing a problem while splitting a text file, I need to split a file into some parts and each split file should have 2000 lines, when I do it through "split" command the mother file is kept intact but as per my requirement I need to cut mother file into some parts thus it should not be kept intact.
I have a utility that works with files. The utility is crashing at after about 120 files. The input to the utility is a file containing a filelist. I want to cut the file with the file names in it to seperate files containing about one hundred or so. My thought was to determine the number of lines/100 and then use head and delete to create temporary files to run the utility multiple times to prevent the crash. When I tried to create a variable using the wc -l command the output gives me the number of total lines but it also includes the filename of the input file. (873 Filename.txt) I can not figure out how to remove the Filename.txt from the variable.
I am currently trying to copy a directory of roughly 400GBs to dvd, have gotten myself stuck. I tried to tar and then split; however, I don't have enough room on my hard-drive to make a compressed tar and split it up and then burn to disk, so I need a way to tar the and compress the directory, split it, and burn to disk every 4.3GBs.
I went ahead and installed DAR as an alternative, as I hear it is designed for this type of task, but I can't figure out which way is heads or tails.
I would like to split my display in two, so they would behave like two physical monitors, i.e. it would be for example like to connecting two 960x1080 monitors through physical ports. Is something like this possible? The problem is i would like to run two fullscreen applications on second monitor. Is that even possible? I prefer Windows 7/vista but I welcome Linux solution as well
i have xterminus installed. i also have a white block over the first letter in my username and when i begin typing, the 'block-type cursor' just leaves full white spaces behind and i cannot read my text at all. even when i delete back over the white spaces, they stay whited out.
I installed compiz on squeeze. I followed the steps on [url] , everything seems fine except my gnome-terminal shows me a white-in-white screen, seems like both the background and foreground are white, I tried to change the gnome-terminal profile, it doesn't work, after I disable compiz, gnome-terminal back to normal. I tried to install xterm, it can work, but it not easy to use for me, I still want to use gnome-terminal,

Can "locate" or "updatedb" be set to print file names with white space properly escaped? For example, I want it to print, "/home/USER/My Files" and not, "/home/USER/My Files". I've googled around, read the man pages, checked the forum, and I'm still stuck.
I'm trying to update Kubuntu 11.04 here is my error: p, li {white-space: pre-wrap;} E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. here is what i have tried to fix it:
I am trying to use bash 'printf' to format an environment variable.Doing this I get on the screen just the format I need (underscores mean blank spaces):prompt> printf "%10s" "1.23"________1.23Unfortunately, when this is assigned to a variable, the format disappears:prompt> X=`printf "%10s" "1.23"`prompt> echo $X1.23Does anyone know what can be done in this case to get a proper format?Why does not 'printf' respect the left blank spaces when assigning values to a variable?
Id like to share with you a strange behavior I�ve been seen with the printf C language function running in Fedora.The code opens a file as showed:descString = fopen( strcat( stringName, txt), a+);There are also some printf functions in the code.However, instead of the printf functions to print their content at the screen, theyve been printing them in the file with the descString file descriptor.Have you ever seen something like that?To print something to the file I use the fprintf function. I didn't make a mistake to confuse printf with fprintf. I'm sure.
I am looking for this `struct messages_sdd_t` and I need to search through a lot of *.c files to find it.However, I can't seen to find a match as I want to exclude all the words 'struct' and 'messages_sdd_t'. As I want to search on this only 'struct messages_sdd_t' The reason for this is, as struct is used many times and I keep getting pages or search results.The directory I am searching in, has another directories so it will have to search recursively.I have been doing this without success:Code: find . -type f -name '*.c' | xargs grep 'struct messages_sdd_t'and thisCode: find . -type f -name '*.c' | xargs egrep -w 'struct|messages_sdd_t'
15 for(i = 0; i < N; i++) I want to replace "i" with "test" in the line above,whose line number is 15. When I tried this command :15s/i/test/ Line 15 turned to be this: for(test = 0; i < N; i++) It only replace the first "i",but I want to change all "i" in line 15.
For eg: $NUMBEROFPASSES=6.19 to round up I use NUMBEROFPASSES=$(printf %.0f $NUMBEROFPASSES) What I need to do is round up from eg: 6.10 to be 7 and if lower than 6.10 round down to 6
