Performing commands in multiple subdirectories simultaneously. I'd like to run a program I've copied into every subdirectory which takes *.in files in the current directory as input files. I can find the program, but how do I tell it to run when I've found it?
View 1 Repliesi'd like to execute in several subdirectories that all have the same name, but I don't want to have to change into each subdirectory (there are hundreds) to execute the script. All the subdirectories have the same name ("final_alignments"), but are located in parent directories with different names. All these parent directories are in the same "super parent" directory. I've tried to do this using "for/do" and "find" but no luck so far.

I tried the coding posted above.
find . -type f -printf '%p
' | while read file; do
oldfile=$(basename "$file")
newfile=$(echo "$oldfile" | sed 's/[^A-Za-z0-9_.]/_/g')
if [ ! "$newfile" == "$oldfile" ]; then
echo mv "$file" "${file%$oldfile}$newfile"

I installed 2 nic cards in my pentium 4 computer running rhel5 to be used as a proxy server and connect 2 computers in each network card for testing . The problem is I cannot ping or use the 2 cards simultaneously . One must be deactivated for the other to be ping . The Network configuration panel indicate both card status as active but i can only ping the first to be activated . I have already set onboot=yes to both cards but still the same result after restarting . The nic cards are onboard - Realtek RTL8139 and pci -3com 3c905b.
View 4 Replies View RelatedI am looking for software (Windows or Linux) that can do the following: Resize one image to several provided sizes. Detects the type of the picture (wide, normal) and does the resize based on that. What I mean by that is that it should not break the image by shrinking it more in one direction then in the other so it looks weird. The purpose of this is my Blog. If I want to give my readers a wallpaper, I want to give them several options for the sizes so they can have it in their own preferred screen resolution. The image must however keep its original aspect ratio.

I have a machine with 8 cores. I have a directory of input files that I need to process using a non-parallelized program. I would like to write a script that works its way through a list of commands executing 8 commans (i.e., instances of this program; each with specific flags having to do with the current input file) until the list of commands has been exhausted. Is there an easy way to do this?

View 1 Replies View RelatedI have been working on a project for a while now that involves a rather complex daemon that has to be simultaneously running different tasks. For example one of these tasks is to receive IP packets from the Netfilter queue and place those packets into one of several internal queues. While other tasks involve taking IP packets from those internal queues and processing/manipulating them and finally returning them back to the Linux network stack.
As I as I have no previous C experience before starting this project I just spawned a new thread each time I needed the daemon to be doing something else while those other tasks continued to run. Is there any other way of doing this or is this pretty much the only way of doing this? Because C is procedural I could not figure out any other way of doing accomplishing what I wanted. Should I have done it some other way or is this the correct and only way I could have gotten my C app to be running multiple tasks at the same time?

On that note I guess I could write the Macro in python if there isn't anything out there that does this. However I read that open office only works with python 2.3.5 or something of that nature, and I have already installed 3.1. Is that still going to be an issue?
Here's the setup: One x86 server (Red Hat 4) with two serial connections to an embedded linux device. One serial connection is to a power control so the device can the restarted, and the other is used for a console to this device. Both serial connections use minicom. People on my team VNC to the x86 server, where they find the two minicom sessions waiting for them as they are left open. I would like to automate connecting to the server and communicating over the serial lines.
Supposing I use ssh to the x86 server, could minicom be used over the serial lines without terminating the minicom processes seen through VNC? If not, is there a way to re-open those windows from within the ssh session, so a user who VNCs to the server won't have to reopen them? Could a single ssh connection control two minicom terminals simultaneously, or would there need to be two ssh connections? It is assumed a user and the automated process will *not* try to access the device at the same time; the automation would trigger during off hours.

View 10 Replies View RelatedIm trying to create some screencast videos on Ubuntu. As its a well known fact we dont have a very good screencasting too like Camtasia(only windows) on linux.
After googling extensively I zeroed on Xvidcap for screen capturing and Audacity for audio capture.
According to tutorial [url] first we need to run Xvidcap (do the screen capturing recording first) and then again use Audacity for audio recording .. then mix both video and audio.
I guess this is a pain staking process (running video and audio recording seperately), I thought of running Xvidcap and Audacity simultaneously, if i do this xvicap works perfectly (video capturing happens) but audio capture through audacity does not work.
Note: I even try to run the above tools from seperate terminals/consoles (assuming they are seperate processes)
I even disabled 'audio' in xvidcap and tried to run both at the same time but audacity refuses to work.
I think both the tools are trying to use the same system resources ... and audacity is unable to get hold of the required resources.
Can we run both independently at the same time ?
Is it possible to output one playback stream to multiple devices simultaneously with the current PulseAudio / Phonon setup? The PulseAudio mixer only has radio buttons to choose one device per playback stream. I believe the hardware is capable of this, since I remember doing that before we had PulseAudio. How can I duplicate an audio stream?
Here's one application scenario: I am travelling with my family, all crammed in small hotel room. My wife and me want to watch a movie on my laptop without waking up our kids. I just happen to have one analogue headphone available and one wireless USB headset with me. (Of course, the low tech solution is to bring an 3,5mm Y-cable to attach two analogue headsets, but I would really love to use the USB headset together with the analogue one.)
Another similar thing that bugs me is that my laptop's built-in speakers now always seem dead when an analogue headphone is plugged in. This is mostly what one wants, and before PulseAudio, one had to manually switch them off which was generally annoying. However, the downside is for example with notifications.
For example, before PulseAudio, I could configure Skype to always ring over the laptop's built-in speakers, regardless of whether the analogue headphones were plugged in. This is no longer possible, since PulseAudio does not distinguish between built-in speakers and built-in analogue port any more, while old Alsa did. So in my office, where some analogue headphones are plugged into the docking station, I never hear Skype ringing if I don't wear the headphones.
In windows xp, i created another user account. Now i can run a second instance of any program by right clicking on it and selecting Run as. Is such a thing possible in linux (centos or ubuntu) in graphical environment ?

I have a C program that can run disconnected ( like most ), is there a programmatical way to tel if the program is running without a terminal?

How to submit multiple jobs onto a Linux server. The only way I know to submit and run a job on a server is using qsub, and verifying the status of the job using qstat. I usually run my scripts using qsub -cwd so that I can run it on my own directory (instead of having the results sent to a scratch folder).
1. However, assuming qsub/msub are not available, is there another way to do it? What commands can I use instead?
2. I know that some jobs can run in the background, is that an alternative? How do I do it? And would I still be able to check the status of the job or delete it?

Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.
