I am just starting out in LINUX and I know the basic commands but I am a having a problem. I scoped the man pages but I can't get it. Maybe one of know... Can anyone tell me the cmd to figure out the system a file was created on? I just can't figure out this problem.

I'm a little bit confused with partitioning the filesystem in Linux. the difference between creating the file system with fdisk and mkfs (when formatting the disk). I can't clearly tell my problem, so please look at this picture:

View 1 Replies View RelatedUsing C++, I want to process sub-folders on my home folder sequentially each with a special naming format and containing some binary files in it:
Code:
1/
2/
3/
4/
5/
6/
...
Give above folders, I will process files in 1/ at first, 2/ at second, 3/ at third, and so on.
For some n/ folder, if I realize that n/ actually does not exist in local file system, I do not want to wait for it. Hence I will keep processing (n+1)/ folder, and so on.
However, when processing some (n+m)/ folder, previously not processed n/ folder may have been created on local file system. In this case, I do not want to miss processing it, but somehow detect its creation and process it. After processing n/ folder, I want to continue from (n+m+1)/.
I have created an image out of 2 other images using the "montage" command. I want to then print it using "lpr". I view the output from montage in XV and it looks fine however when I try to print, it prints the bottom half of the first image then the second and then the bottom half again.
E.g., imagine this:
Code:
<< end of top image
<< end of bottom image
The above is how it looks in xv however when printed, it looks like:
Code:

I really can't understand it, I've tried opening and saving the image again but it still prints as above. I don't know if montage is outputting it incorrectly or something, however it looks right on the screen!
Does the dump command back up entire file-systems or is it capable of backing up subsets of a file-system? And is tar capable of taking device names (for file systems) as input to be archived?

As a strategy for learning linux I have decided to adopt using a lean windows based approach. I want to focus on command line machine system, network basics, and file management knowledge. In other words find out how desktop manager does it's business, so I know how to master my machine, but by and large once I have made my choices, leave it alone to do just that.
I figure I should know how applications are internally configured etc., but I also figure an apps GUI and config choices should take care of installations, and program usage as in M$ windows. Surely taking care of an applications dependencies are the responsibility of the developer, are they not?
I am working my way through "Rute User's Tutorial and Exposition (Version 1.0.0)" right now for an overall viewpoint. Can anyone suggest a specific source for a point by point explanation of the command basis of a generalised "desktop management" application (KDE,LXDE)? Better yet would be if it had some parallel comparison of the varied approaches taken by different distributions of linux.
A secondary question, is that allowed? Up to a certain point in Ms windows, a thorough knowledge of DOS 6.xx would theoreticaly enable one to more or less duplicate the actions of the windows overlay. Is there a basic distribution (or subset in all of them maybe?) of linux that would be consistent with that paradigm? What would be analogous to DOS batch files, or GM-Basic? Oh! that's 3.I am certainly appreciating the depth of this forum, and the breadth of knowledge among you forumite's. Reading it is time well spent.

a) The process ended with a 88GB file size (which is ok) but with the following message.Code: tar: Exiting with failure status due to previous errors.I have searched a little but I could not find what went wrong.
b) What are the limitations of tar and gz for backups. Of course I fully understand that they can not be used for differential backups (if it is called like that)
c) Let's say that my backup will be a file of 100GB and I want to see the contents of the .tar.gz. In kde there is a program called ark. Can ark handle so big files? Does it use my hard disk (eg. /tmp) to uncompress the file so to show me its contents? It might be the case that might be the compressed file is much bigger than the left space on the hard disk?
d) How can I do an integrity check when my tar.gz file is created?
To be specified,what I want to do is:
if I create xxx.php,#!/usr/bin/env php will be the first line of the file
if I create xxx.py,#!/usr/bin/env python will be added first.

View 2 Replies View RelatedDebugging some of my scripts after upgrading from Debian Lenny to Ubuntu 10.04. In so doing, I tripped over this "problem," the solution to which may give me a clue to others.
On a bash shell command line I created a file thusly:
sudo touch zero_file
and it lists as expected with default permissions 0644:
-rw-r--r-- 1 root root 0 2011-03-09 11:18 zero_file
But then this command fails
sudo echo abcdef >>zero_file
-bash: zero_file: Permission denied
I can place the command (minus the "sudo") in a script & run it under the auspices of sudo & it works. Am I missing something re the stdin redirection when using sudo?
i created a script file named myscript.shi ran this by typing sh myscript.sh and i got my outputbut,when i tried to execute by typing ./myscript.sh i received permission denied errori gave permission as chmod 777 myscript.shthen i executed by typing ./myscript.sh . It worked fineso i wanted to know whether using sh and ./ with permissions are same.. ?or did it work for only this.. are there any differences

It runs perfectly when I do java -jar file.jar in the command line, but there's trouble when I double-click the file when running from the file system manager. I've tried a custom command under properties ie java -jar, but the problem is that the .jar file doesn't seem to be able to use any of the files in the same directory. When running, the jar can't find any of the files that it needs.

View 2 Replies View RelatedI think that the biggest problem that I have had is that some of the music (and audio books) that I have gotten have not played on my walkman, or have not been able to be downloaded in to I-tunes.
First: I hate itunes... I only try to make it work because I love my wife. (and do not want her to hit me)
Second: I know that my Walkman has a very limited range of files that it can play, so I will need to convert some types of files.
But my basic questions:
* How can I figure out what format a file is in?
* Below that, how can I identify the singular characteristics of a file? (bit rate, and other formats...)
* Is there a best way to switch the formats or format options of these files. (I am currently using sox to do this, it seems to very complete)
Basically. I know nothing! The most that I do not know is that two files that as far as I can tell have the same formats, and should work the same never the less, one of them works, the other does not. I am looking to figure out a way to look at these files (maybe they are mislabeled) and figure out what their real format is (and a more complete format than just being MP3 or such) and then to be able to convert it in to a format that is able to be used by myself and/or my wife.
