General :: Getting Input From A File?

Dec 2, 2010

I am trying to input from a file. The file's layout has three columns; a department number, a first name and a last name, each separated by a space, for example:

Code:

781-89-4271 Amy Balduff
839-98-4072 Brian Becker
846-43-4284 Christina Brendon

[code]....

I need to input the words through separate variables because I will be passing them to other programs as soon as I can figure this out.

General :: Xkbprint Error: No Input File Specified

Mar 18, 2011

when I try to print the current keyboard layout with "xkbprint -o layout.ps" it gives me the error mentioned in the subject. I also remember printing it a couple of weeks ago (and I'm sure I didn't specify any additional options), but now it just doesn't work. Everything I read on the Net assume this command prints the current layout, and so far I haven't discovered even the slightest mention of this error. It's a trifle, but it drives me mad. What could I be doing wrong?

General :: Bourne Shell Input From File Using - Then Return Control To User?

May 5, 2011

I have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).

Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands

The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?

Ubuntu :: Pdftk Output File With Pages Extracts Same Size As Input File?

Apr 22, 2011

I am curious if perhaps I am doing something wrong extracting pages from a pdf doc using pdftk and creating a new file. I am only extracting the odd pages from the file and outputting them to a new file that is now only 20 pages instead of the input's 40 pages, yet the new output file is still 1.4Mb in size, the same as the original.

It seems strange to extract only half the pages of a large document and end up with a result that is the same size. how to streamline the resulting pdf's using pdftk?

BTW this is the command I am using, in case perhaps I am missing an option to optimize file size or something:

Code:
pdftk A=ch15.pdf cat A1-40odd output odd.pdf

Programming :: Splitting A File Based On The Values Read From An Input File?

Jul 27, 2010

I am splitting a file based on the values read from an input file. The below one is the script.

1)How do I add the header which is present in the original file to the new split files created?(For eg. pharmacyf conatins header as table column names. The new files created (ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat) are without the header).

2) Also the script is creating 0 byte files for the pharmacyids which are not available in the intial file? Can this be avoided?

for pharmacyf in *
do
tablename=`echo $pharmacyf |cut -f4 -d'.' `
while read pharmacyid
do
grep -w $pharmacyid $pharmacyf >> $OUT/ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat
done< inputfile
done

General :: Scripting - Feed An Input File Into An If Statement Line-by-line

I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.

I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.

The error I am getting now is ./script.sh: line 6: [: : integer expression expected

Sample input $FileName

Server :: NFS Large File Copies Fail - Error Writing To File: Input/output Error?

Jun 27, 2009

I recently upgraded my file/media server to Fedora 11. After doing so, I can no longer copy large files to the server. The files begin to transfer, but typically after about 1gb of the file has transferred, the transfer stalls and ultimately fails with the message:

"Error writing to file: Input/output error"

I've run out of ideas as to what could cause this problem. I have tried the following:

1. Different NFS versions: NFS3 and NFS4
2. Tried copying the files to different physical drives on the server.
3. Tried copying the files from different physical drives on the client.
4. Tried different rsize and wsize block sizes when mounting the NFS share
5. Tried copying the files via a different protocol. SSH in this case. The file transfers are always successful when I use SSH.

Regardless of what I do, the result is the same. The file transfers always fail after approximately 1gb.

Some other notes.

1. Both the client and the server are running Fedora 11 kernel 2.6.29.5-191.fc11.x86_64

I am out of ideas. Has anyone else experienced something similar?

Debian :: Input File For Pdftk?

Apr 21, 2011

This is a question for those that use pdftk. I've been using it for about the last year or so to combine manipulate PDFs and it is awesome. Until today, mostly what I've been using it for has been for less than five files. Today I have been working on a manual at work which consists of about 100 separate files with a total page count of 167. The pages are a mix of 8.5x11(inch) and 11x17(inch). The pages needed to be in a specific order, the only way I could think of to do this instead doing this all in the CLI, I created a text file which contained a list or sequence of the files. To make it easier for me to read and group, I first put each file on a separate line.

chapter1_separation_page.pdf
file1.pdf
file2.pdf

OpenSUSE :: Amarok 4.4.2 - How To Input File PATH

Apr 4, 2010

I upgraded my OpenSUSE 11.2 KDE 4.3.5.x to KDE 4.4.2 and am having a couple of issues. Not sure if I am just a bit stupid or impatient figuring them out or what... In Amarok, I used to be able to input or edit the path name under Files (i.e. Browse Local Harddrive for Content). This allowed me to quickly copy and paste a location from Dolphin / Konqueror etc. into and from Amarok for quick access across multiple applications (Especially when sorting out things). Somehow this is either missing (Not possible anymore) or I am to impatient or stupid figuring this out.

Software :: Overwrite Same Input File Image

Mar 18, 2011

Code:
dd bs=8192 if=Image of=/dev/PS0
In the above command, I cant able to understand the option "of=/dev/PS0"

Whether it means,
1) to write the input file "Image" in to "/dev/PS0" of the Floppy device
or
2) to overwrite the same input file "Image" in a file format ("/dev/PS0") of Floppy.

Programming :: C - User To Input The Name Of A File As An Argument

Aug 5, 2010

Write a program that requires the user to input the name of a file as an argument. If the user fails to include one argument it should make use of a thread that handles a signal. The signal handler should tells the user Incorrect number of arguments and then calls the terminate signal on the process.

If the numbers of arguments are correct then the program should allocate memory space to the file (5MB) and create a child process that requests the user for a character that it should send to the parent. The child should keep request for data until the user keys in the character O. During each request it should pause for 10 seconds, send the character to the parent and then requesting again for another character.

The parent should get the character from the child. Do not make the parent wait for the child to finish requesting for data. Make use of pipes to facilitate communication between the parent and the child. A second child should be created to read and display data from the file. Make use of any appropriate Inter Process Communication technique to ensure that the second child and the parent do not access the file simultaneously (Mutual exclusion).

Programming :: Read Each Line Of A File As Input?

Jun 21, 2011

I'm writing a program which now accepts user input:

Code:
echo "Enter a date in the format YYYY MM DD hh mm ss."

read gregyr gregmo gregdy greghr gregmn gregsc This lets the user input a date and time, such as 2011 06 21 15 12 45, and have each number assigned to their corresponding variable. Later in the program, these variables are put into an equation, and then the terminal spits out the answer. Now I have to have the program read all of the lines from a text file, which is in this format, assign the variables.

Ubuntu :: Cannot Open File: Input/output Error

Nov 11, 2010

I just received a 1TB external(Western Digital) hard drive(NTFS) for backup purposes. I'm using an Ubuntu Live CD, and an external hard drive dock. I am transferring over esata and am receiving the error:

Code:

Cannot open file: input/output error

Seems strange that it said "open". At any rate only about 60 of the 200+ GB were able to be transferred over...this won't do. I have tried to copy via CLI using

Code:

cp -r

and received the same issue. For clarification I am attempting to transfer from a mounted partition onto the mounted external.

Programming :: Graycode To Hexadecimal Converter From Input File?

Aug 25, 2010

Design, debug and test a C program that uses Gray Code for decoding information stored in a binary file. Gray Code G(A)of any value A can be easily produced from unsigned binary B(A) using the expression: G(A) = B(A) ^ ( B(A) >> 1 ) (1) The formula may be used to generate coding tables. For example for 4-bit codes:

Table 1. Coding table

Hex Value Binary Gray

0 0000 0000
1 0001 0001
2 0010 0011

[code]....

If the first option is selected, your program shall prompt the user to enter the file name and open the specified file. In this assignment you can presume that the file size is always limited to 64 bytes. If the file is not found, the program shall display a message: File not found and display the menu, so the user can enter file name correctly or exit the program.

Ubuntu :: Canot Remove File Input/output Error

Apr 8, 2010

I got a new HDD like a Storage on my Ubuntu ,it is formated as ext3 and i am able to mount it ,but sometimes while downloading from FTP ,when the session broke Ubuntu crates some ./afternature.mp4 Input/output error ,which i can see on "ls -l" ,and that causes great troubles to me ,because i can not copy or write on that disk another file with the same one which is created like this ,these error are gone only if i format the hdd .

My mounting command is "mount /dev/hdb3 /tmp/hd ext3 rw 0 0" So is that possible to remove these error without formatting the disk . PS:I did a lot of search for that error ,on unix forums also here but i didn`t find a concrete answer ,i found a thread which is for that case but removing with inode is impossible because on ls -l i`m not receiving the inode .
