I'm trying to write a bash script that will simultaneously ping a host and execute a traceroute at the same time. I would like the results to output to a text file.

what i want to do is run two commands (nautilus and gedit) from the command line/shell script at the same time. i can obviously do && between them, but this requires the first app to close before moving on to the second one. i want to run both apps at the same time so i can run gedit with some project files open on it, and nautilus to browse those files/other files.

How can i tell audacity to use this?

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?
I 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?
I have been having a freaky experience where Firefox appears to freeze up and brings down the terminal and any process viewer with it. For example, I can open a gnome-terminal or xterm window, but the moment I press a key, that window freezes up as well and must be force-quitted with the Force Quit panel applet. In addition, the System Monitor applet I have on my top panel freezes. It's really weird.
I began having this problem around a month or two ago. I thought it was something to do with something I installed, so a week or so ago I did a clean install, backing up my documents, Firefox profile, and GNOME settings from the old installation but wiping everything else (I'd already ruled out the Firefox profile by renaming the folder and creating a new one from the profile manager). Yet the problem persists.
I'd be happy to post any output, but as bash (including Ctrl+Alt+F1 command line) freezes as well, it's a little hard to treat the problem when it happens. One more thing: I am on a university campus which uses 802.1x encryption on both wired and wireless connections; is it possible that that is causing the crashes?
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 Replies View Relatedi'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.

View 4 Replies View RelatedHere'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.
below are the details of my system. I have bash as my current shell, some really common commands aren't working.

I 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.

View 3 Replies View RelatedIs 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.
I installed 4 encrypted partitions (/, /var, /tmp, and swap) that are mounted at boot using the Alternate Installation Disc, and they all have the same password, but I have to type that password in 4 times when booting up. How do I make it so I only need to type in my password once?
View 1 Replies View RelatedI have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?
What happens when the script executes is that the ssh connection works and parks me at the remote hosts's shell login. Therefore, the "firefox" command refuses to execute. I need to know how to make the "ssh" connection occur, stay open, and go into the background so that the rest of the script can execute.If I could also do this with the "firefox" line so that the entire term window could be closed would also be helpful.

I created a application launcher (type:terminal) to replace the index.php on my apache server (/var/www/) with the index I keep updated on my desktop.
This is the exact script I'm using on the launcher:
My idea was the launcher would delete the current file at /var/www/, and then copy the file on /home/andre/Desktop.
But its not behaving properly, it is deleting both the file in my /var/www/ AND my desktop.
With xterm, I can do the following, and the scripts are executed sequentially in a single xterm: xterm -e 'script1.sh;script2.sh' But with gnome-terminal, when I do: gnome-terminal -e script1.sh;script2.sh It runs them in parallel in 2 different terminals. I've tried a few combinations of ", and ', around the scrips, but no difference.

What bash command can I use to rename or change the extension or name of a batch of files (for example, from .php to .html)?
Furthermore, is there a simple bash or python script/command that can be used to open a batch of plain text files one-by-one, search for all instances of a specific word, and replace all of those instances with another word?
