I wanted to stream audio and save it into a file which I can then listen to at a later date.
Ive found a source that provides a m3u file. Example : [URL]
Is there anyway which I can pipe / save this audio stream into another file using just a standard bash shell.
I blame myself but I am lazy person. Now I am trying to learn a bit a bash scripting. But saving any script to see how it works is so boring. You know these exercises:
Code:
Now save this in a file - say helloworld.sh (haha), chmod and execute to see
Code:
Is there a way to execute text as a script? I mean
Code:
Once I bring up alsamixer, or mixer from menu, how do you save the settings and have them restored next boot so you don't have to always set them again after a re-boot up?

Vim 7.1
I do 'vim c1 c2' and I begin copying parts of c2 to c1 (yank, put). Now, each time I go back to c2, I must save c1 first. But it happens that I'm not sure I want to save it. Is there a way to go back and forth between c1 and c2, making changes to one of them, without having to write to disk before switching? Notice the changes must be kept.
I want to save notes against a file on linux... i want to save meta data about a file..because the file names are restricted in max length...So how to save notes or comments about a file on linux so that it gets saved along with the file itself...I used the notes tab in the file properties dialogbox.. but that way the notes stick to the file only on that OS only.. if i open that file in another linux os.. those comments/notes are gone...Way to embedd these notes into the file so that i dont lose them ever..At lease a solution that makes this possible on switching linux distros. if its not portable enough that these notes stick b/w windows and linux its ok for me.. but atleast if i format my linux os.. atleast i shouldnt lose those important notes..and be able to access on newer linux..
And i also have no idea if this notes tab was implemented to be linked with the OS only.. i dont see much use of it.. and a normal user also has noway to know this.. i also came to know on superuser chat from a buddy.. @Sathya ..this thing is more useless especially if u use ubuntu which has 6 months timeline..and crazy people like me who are always eager to upgrade their os as soon a new one is available..and any way i can search these notes from the terminal?
I am using system() command to save command output in txt file and i am storing in one character variable.

I connect with ssh to an Ubuntu server to edit some files in /var/www witch I have set the setgid bit:

I have added the user "user" to www-data group. Now I connect using ssh as user "user" to my server with nautilus. When I copy files using nautilus file get the group permission 'www-data' as they should. But if I edit a file using Gedit and save it, the file's group get changed to "user" group ?

I listen to a radio show that broadcasts online a lot named ChatterBox Video Game Radio, and when i e-mailed one of the hosts about retrieving archived shows since the site didn't have any archiving of old shows or a link to it. Alon was nice enough to send me one of their old web pages with a HUGE list of archives but it's only the xml source code of the page. since the page isn't live of course, and because of the how he had to send me the code for the page and not a hyperlink to the page, i have the source code. now going through the source code of the page he emailed to me, i can find links to .mp3 files and i can open them and listen to the shows in web browsers, but i was hoping to save them to my computer forfuturelistening.URL]ww.chatterbox'ssite.com/whatever/anotherfolder/showiwanttosave.mp3 in firefox quicktime comes in and lets me listen (as long as my internet connection is active) but wont enable me to save because i dont have the pro version of quicktime. quicktime is good, but i dont use it enough to actually buy the product, and i'm not going to buy the product for just a one time use. is there another way to where i can save this file using the address from the source code (and the ChatterBox allows listeners to save their shows to computer for free, so it not some work around to rob them of money. i fully support them) without having to buy quicktime 7 pro(a product i never really use)?

-rwxrwx--- user1 group1 file1.txt
-rwxrwx--- user1 group1 file2.txt
When user2 (who is also a member of group1) edits file2.txt the permissions change:
-rwxrwx--- user1 group1 file1.txt
-rwxrw---- user2 group1 file2.txt
user1 then has issues opening the file. This also goes for new files that are created (they are missing the group execute permission).

I am accessing a firewire camera using the libdc1394 library and saving the image as a PPM file, using the code below:
[Code].....
My question is whether the above code is portable. I presume it is, since the result is a binary PPM file which should be capable of being read across multiple computers with different architectures and different operating systems. But at the same time, all that the above code is doing is just saving the binary representation of unsigned chars on the harddrive, and there does not seem to be any reason why the binary representations of the unsigned chars will be identical across multiple computers.

I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?

I am new to Linux and I wanted to setup a dedicated game server on my notebook.
I've installed Ubuntu 9.04. I than created a directory named /home/phlex/kfserver. I downloaded the application binary from Steam. I changed the file permission with chmod +x hldsupdatetool.bin and now the file attributes are -rwxr-xr-x.
The problem is when I try to run the binary file. If I type ./hldsupdatetool.bin I get an error message "-bash: ./hldsupdatetool.bin: No such file or directory. It seems the OS can't find the file. I've downloaded the file several times thinking it may have been corrupt but it's not. I can delete the file, I can rename it and so the file is there. Sometimes Linux can be aggravating to use.
I am supposed to take some small files, and print them to a specific printer, such that the small files are concatenated into one file. The file name has to be included in the file that gets printed.
Should I be looking to concatenate the files into one file with the file names included, and then print them?
something like: -printfunction -printername < file*

I open an ODS file and edit it and save, fine. But sometimes and for no readily apparent reason it refuses to save the document with the error message:"Error saving the document <filename>: Write error. The file could not be written". I have upgraded my version of OpenOffice but the issue remains. Once it starts with that error the only way to save the file is to actually abandon my change and restart OOffice. Today I lost an hours stuff as the auto save was also failing but not giving me any warning it was failing. I'm not sure if this is an OpenOffice, file system, Fedora or permissions issue though I've not noticed anything similar with other applications. Have set permissions to 777 but still get the error.

As soon as scan completes, the xSane windows(2) disappears and there are no copies in the intended save folder in Documents. Upon original attempt, the xsane windows had an additional third "Preview" window which has not returned since that first scan attempt?
One is not a computer guru by any imagination!
Info; the scanjet worked very well on the other "doze OS" and seems now, does not in the Ubuntu OS. In Doze, there was also a program for a HP PhotoSmart 3200 running and when I added the scanjet it might have been happy with that driver. Currently I do not have access to the driver disc for the 3200 with me. Too, it now takes ~45+ seconds for the scanjet to begin as compared to 2 - 3 seconds on doze.
Some internet self help searching seems to suggest the xSane 1.0.18 is the driver choice to use with the HP 3500c scanjet. When attempting to download, an archive "Failed" notice appears. I am a bit lost from here.
