When inserting/removing a usb device to a board based on linux system, an output is given:
Code:
# mmc1: card 0001 removed
mmc1: new SD card at address 0001
[code]...
I'm not sure about the following behavior so thought I would put it out to see if there is an error I need to resolve, or simply a process that I need explained.I'm also not sure if this is an Ubuntu issue, a Linux issue, or other... but here goes.I ran my "make build" in two different ways; one with just "make build" and one with "make build > output" (so I could review the full script).With just "make build" the process finished and returned to the command prompt.
With "make build > output", after the process had finished (script in output document identical to what was in the terminal with "make build") a new set of data was displayed in the terminal (see below).With the other examples of using "make build > output" the times it would parse something back to the terminal window was when there was an error. As I fixed the errors these breaks back to the terminal window would stop. So I'm wondering if this indicates a new error, but because the "make build" now completes successfully (at least it appears to), I'm wondering if this data in the terminal window is just a behavior related to redirecting the output script using the ">" process and something to do with returning to the terminal once a process completes
I have a problem when using awk:
e.g: awk '{processing text}' File1 > File2
But when I'm processing the File1, I want to print out some messages to the screen (not the File2). How can I do that?
I have written a script and included the command
Code:
set -x
to see what happening when i run the script
I have seen a post where someone was explaining the virtuality of stdout and stderr and that it can be redirected with e.g. 2>file.txt but this apparently is not working for me!
I have a CUPS filter with fprintf(stderr,...)
This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;'
FIL=~/replication-`date +%F`.txt
MAILTEXT=~/mailtext.txt
touch $FIL
$CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.
I would like to get the command and it's output redirected i have tried using the below but my syntax seems to be incorrect .
<<EOF
$(ls)
EOF
So I have a DAC/Headphone Amplifier which plugs in through USB. Through the system settings I'm able to set it as the preferred audio output option. This makes all the windows manager sounds come through the headphones, but all the applications still come through the laptop speakers; i guess they are completely independent of the system settings. I have to set each application's output preferences separately, and some software (like Firefox) doesn't have any output preferences. So is there a way toirect the audio output of all applications to all come through the USB DAC
View 4 Replies View Relatedi created a sample module and while trying to insert it i am getting the message "Killed". But when I did lsmod my module was listed out there and was 'Used by' 1. Maybe because it is in use I cannot do a rmmod on my module. How to overcome this, that is do a rmmod while it is still in use?

View 12 Replies View RelatedToday I tried to use padevchooser on Natty to send my laptop audio to my home media machine (which has the good speakers) using the "default server" option. Turns out padevchooser doesn't work on Unity and the threads I have seen say it is deprecated for other gui tools,
So what is the easy gui way to switch from my local pulse server to another one on my LAN, without using padevchooser, or switching off Unity? Or is this a regression?
I've got a C program that I've added some 'printf' statements to monitor a couple of variables. When I run this program manually or from a script, the output is displayed on screen. However, I need to change various variables in the 'test.c' file, run 'make clean' and 'make' a few hundred thousand times. I'm using a script to read the variables in and then using sed to do in-place edits of the file. Unfortunately, with this amount of iteration, it is getting rather tired!
Anyway, I've created a script that is working as long I respond to prompts. I've tried the following to no avail: Code: /path/to/script > /tmp/output /path/to/script > /tmp/output 2>&1 /path/to/script | tee (no output even after adding the -a option) In my C program, I have the following 'printf' statement: Code: printf ("variable1: $s variable2: $s",var1,var2); What am I missing? I've worked with redirection before and it's always worked out fine, but this one plain stumps!
I am developing a application. In this I fork() 3 childs(lets say child1 , child2, child3) . The parent is now waiting for some input from keyboard.Child3 is continously getting data from child1 and child2 using pipe which it then will print using printf.Now as the parent is waiting for input from user through keyboard while child3 is continously printing the data. I want to do it in different terminals.Can you please guide me how to proceed ahead so that on one terminal , the parent waits for input fromser while on other terminal child3 prints data.

View 3 Replies View RelatedI finally decided to transition to a 64-bit install (AMD64). (same machine, just reinstalling as a 64-bit kernel starting w/ a Debian squeeze netinstall image) My audio chipset is nvidia MCP61, and it was working perfectly under a 32-bit kernel (I did the transition because a poorly-written system backup script (my fault) hosed /usr, /bin, and /sbin) When everything was up and running:
*: KDE4 only recognized the output device as ALC1200 Analog
*: kmix only had a single channel(master)
*: alsamixergui did recognize all the channels
*: some games (sauerbraten, for example) had no sound in KDE4.
*: some games (warzone2100, for example) did have sound in KDE4.
*: the games that had no sound in KDE4 did have sound in fluxbox.
I removed the following packages (some of which I had installed to try to get audio working properly):

I want to turn an old (2004) compaq computer into a webserver using debian. 2.8ghz celeron, 756mb ram, 80gb IDE HD.I installed debian through the first DVD, without laptop and desktop environments, and did a guided partition.This is the second time this problem has occurred, at first i thought i would try re-installing, but no avail.
As soon as i turn the computer on, i get a grub loader screen with two options, Debian or single user debian. Both choices present same issue. Once i select either one, it seems to load then says "fatal: error inserting fan: no such device." Continues to load, and then "fatal: error inserting thermal, unknown symbol in module"Continues to load then "volume group ***** not found, volume group ***** not found" "enter pass phrase to unlock disk" I enter the pass phrase. "Successful" then a bunch of stuff loads and hangs at "end trace de8............" And it won't let me type anything or do anything except hit the power button.
When I run dmesg I get
Code:

The primary hard drive with windows on it died, and since we have been using ubunto 9.10 exclusively, I just removed the dead drive, changed the jumpers on the secondary drive to primary and did a clean install on the drive which presumably formats the disk before installing.
