Software :: Writing An ISO File For Cd Audio From A Cue And Wave File?

Nov 30, 2008

I am running Intrepid Ibex 64-bit, and I have recently ripped a cd with EAC on one of my windows boxes, and it produced a cue sheet and one single wave file for the entire cd. My question is this, is it possible to take the wave file, burn an ISO image that acts exactly like the original cd? In other words, take the single wave file, using the cue sheet splitting it back into it's individual tracks, and then reading the subsequent ISO image from a program like Sound Juicer, so it can write all the metadata and convert it with my own preferences. I know this is a very strange predicament, but it's one that would save me a world of hassle.

Software :: Unable To Author 24-bit Audio CDs Either From A FLAC File Or From A WAVE File?

Aug 16, 2010

Kernel 2.6.21.5, GNU (slackware 12.0).
KDE 3.5.7
K3b 1.0.2

I have a FLAC file with 24-bit samples instead of 16 bits. I could use the flac linux command to obtain a WAVE file and then cdrecord to burn the audio CD. Unfortunately, cdrecord requires 16-bit digital audio as input. Is there a program able to author 24-bit audio CDs either from a FLAC file or from a WAVE file?

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?

OpenSUSE Multimedia :: Rip Audio From One .mp4 File And Then Generate One .mp3 File

Dec 19, 2010

So I use the following to rip audio from one .mp4 file and then generate one .mp3 file.

Code:
caleb@linux-vmp1:~> ffmpeg -i a -ab 128000 -ar 44100 01.mp3

Obviously, this takes a file named a and makes a file named 01 that is an mp3. It works great and I have used it many times. The problem is, I would like to rip the audio from several files all at once. I am sure there is a way to do it but I haven't stumbled upon the way to do it.

General :: Writing Text To A File?

Mar 18, 2010

I am using Grass GIS

I have written a script which outputs a list of numbers to a file

code snippet:

r.stats -1 fs=, input=Bones_AVE > /home/gary/AVE_monte_carlo/rstats_AVE$i.csv

so this makes acsv file with one column. I want to run it again but rather than outputing to a new csv i want to add it to this one as the next column. For this example there will be 100 rows per column.

the 1st one will make the file

[grassGIS code]> /home/gary/AVE_monte_carlo/rstats_AVE.csv
add ',' after each value
the next one
[grassGIS code] open file /home/gary/AVE_monte_carlo/rstats_AVE.csv

Ubuntu :: Avoid Users Writing On The Same File?

Feb 27, 2011

Is it possible to forbid that more then one user open the same file in rw mode? In windows when you open a file that another user is using, there's ad advise and you have to open it in read only mode

I installed ubuntu 10.04 desktop edition on 3 pc (there is not a server-client architecture). I installed samba.(and smbfs)

put the strings:
[name]
comment = ...
path = /...
guest ok = yes
read only = no
create mask = 0777
directory mask =0777

Computers that access to that directory do (on boot, with root privileges)
mount -t smbfs -o username="user",password="pass" //192.168.0.12/name /mnt/cartelladimontaggio

But if two users access to the same file, both are authorized writing on it! So changes made by one are lost when the other save.

General :: Detect If A Program Is Writing To A File?

Mar 3, 2009

I have custom software that writes to a sensitive large file when the user does something. I would like to make backup copies of The file that gets written to, but if I make a gzip of the file at the same time someone is changing something, it will corrupt the backup because some of the data will be missing, as its backed up during being written to.

a) Is there a way to detect if a file is currently being accessed/written to?
That way if its currently being accessed, I can just make the script wait until its done and then finally back it up.

b) Instead of backing up the large file while it has potential to get written to, would it be better to make a copy of the file first, then gzip the copy? This idea comes from the fact that gzipping the original takes 5-10 seconds, whereas making a copy only takes 1-2 seconds. The less time, the less chance of corruption.

c) Is there anyway to freeze a program or a file to stop it from being written to for an amount of time?

With a, b, and c together. The best solution I have to my problem would be a script that first detects rather the file is being accessed. If not, it would then freeze the file/program and then make a quick copy of it. Once the copy is created, it will unfreeze the original file/program and then go about gzipping the copy.

SUSE :: Writing To Log File Affecting Performance

Apr 8, 2010

I have 3 c files(one of them forks out 5 instances) all writing to one log file. Now to avoid the confusion of opening and closing in each application or instance and running into a situation of not having closed a file I decided to open and close the log file inside the log function for each write.

So what I do currently is fopen, flock, fwrite, unlock, fclose for each write. All the log messages from all the files get written fine and there are no errors but I see a performance hit. The applications talk to each other using SHM(shared memory). So when I try to set a timer and check number of messages lets say I get X messages. Each time I remove or add a log call the number of messages changes. When it is a 1 sec or 5 sec timer it doesnt make a very big diff..few hundreds but when I check it over a longer period..every log call added decreases 1000 messages in count. So I want to know what is an efficient way of implementing the custom log across the application.

General :: Unable To Listen To Any Audio File Due To Lack Of Corresponding Audio Driver Programs

May 10, 2011

I have been using windows operating system for a long time now, but I am not well familiar with linux. Whenever I used to install Windows, I used to install the corresponding audio drivers(in order to listen to the music). The problem I am facing is that I do not know how to install the audio drivers(if they really exist in linux Mint 10 operating system). As a result I am not able to listen to any audio file due to lack of corresponding audio driver programs. make proper configurations settings so that I can listen to audio files in Linux Mint version 10.

Software :: SHA1-Hashing Differs When Writing To A File?

Mar 9, 2011

it is about the program sha1sum to create SHA1-hashes. As you probably know, SHA1-Hashes do have the length 20 byte. So when I just type:

Code:
sha1sum myfile

it produces an output of

Code:
(some20byte) myfile

just as it should. Now I want to store the 20byte hash in another file, I use this command:

Code:
sha1sum myfile | awk "{print $1}" >> myhash

Unfortunately I'm not familiar with awk, but this should cut off the end of the sha1sum output, which is the name of the file again. The problem here is: The newly created file myhash has the size 41 bytes, and printing it out I can see that it is not the original hash (I wrote a little program to print it bytewise).

Programming :: Know Which File Under The Folder Is Being Opened / Created For Writing?

Apr 23, 2010

My program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.

General :: Removing Write Permission Does Not Prevent Root From Writing To File

Feb 3, 2010

I just noticed on my Ubuntu machine (ext3 filesystem) that removing write permissions from a file does not keep root from writing to it. Is this a general rule of UNIX file permissions? Or specific to Ubuntu? Or a misconfiguration on my machine? Writing to the file fails (as expected) if I do this from my normal user account.Is this normal behavior?Is there a way to prevent root from accidentally writing to a file (Preferably using normal filesystem mechanisms, not AppArmor, etc.)

I understand that root has total control over the system and can, eg, change the permissions on any file.My question is whether currently set permissions are enforced on code running as root. The idea is the root user preventing her/himself from accidentally writing to a file. also understand that one should not be logged in as root for normal operations.
