Ubuntu Multimedia :: How To Grep VU-meter From Terminal
Jan 28, 2010
Is there any way to get information about whether something is currently played via the speakers? Is there an app that "scans" the VU-meter (e.g. pavumeter) in a terminal and prints out any information about the current "sound-volume" that goes out?I'd like to create a script that prevents my Ubuntu to suspend while something (e.g. music) is played... I know that e.g. Rhythmbox has a plugin for that, but I'd like to use SongBird...
Can someone recommend a good app to monitor the OUTPUT of my soundcard? I don't just want to look at the VU meter of my music player - i actually want to see what the soundcard is outputting. Windows drivers for my soundcard (Audiophile 192) had this ability, but I'm not sure what software to use in Linux.
I can't get this simple regular expression to work for matching emails: 'w*(?:.w*)*@w*(?:.w*)*w{2,5}'
It should be working as I have tested it with regex pal and it works just fine. I think there's a problem with optional character class but I'm not sure.
After typing "grep some_word" on terminal 6, the system doesn't do a thing, just lets me type endlessly. I've tried "Esc", "q" , [CTRL] + x, "exit" and no luck. I bet I'll kick my ass when you tell me but at the moment I can't figure it out. Rebooting would probably solve the problem but there must be a better way.
I am trying to install Ubuntu 11 with Wubi and the progress meter is missing. I cannot see if it's 30% done installed or 60% or whatever. It's annoying.
I now have a 10 GB cap on my Internet and would like a meter to tell me how much I use in a month , my IP address changes if that matters gnome ,lucid lynx
gnome-terminal from the Debian squeeze does not use the 'default_size_columns' and 'default_size_rows' from the /apps/gnome-terminal/profiles/Default/ folder of gconf.
I have an Asus EEE PC900. Just installed 10.04 netbook remix and everything works fine straight out of the box. it works great and is a vast improvement on windows xp which was previously installed on the asus. Just one small thing - the battery meter is never accurate as far as time remaining goes - it currently says i have 19 hours 55 minutes to go - unfortunately this is not quite true i suspect. It was the same with 9.10, Does anyone have a solution for this?
I recently had to turn ACPI off because of major errors like the child_rip error, but now I don't have battery support or anything like that. No battery meter, etc. Is there a way I can get this while ACPI is off?
I'm using ubuntu 11.04 and have a DSL connection straight from my local telephone (landline) provider.I need a ubuntu app, preferably a daemon/service (that I can start up on boot) that, in essence, can simply log to a file, on a per session basis (with timestamps of course), the bandwidth I use (download + upload bytes).
I'm not interested in logging site info etc., just want raw data usage so at the end of the month I can run some summary reports on it.Basically I was to see if my ISP is cheating me or not (and in general to control myself on my HUGE ..... + ISO download habbits)..I need nothing fancy, even a basic command will do in which case i'll be happy to write my own basj script for that...
As stated in previous posts I've not long come back to linux, I was wondering if anyone can suggest a good lightweight download usage meter to help track how much of my monthly allowance I have used etc.Under windows I was using one that logged into the Bigpond site and would display usage, how much was left and how many days were left till the end of the billing period.I've done some searching but so far can't find anything similar for linux.
i have a problem when using the yum gui it hangs at 1/3 of the process meter and wont budge no matter how long i leave it , using terminall everything works fine and fast but i would like if the gui is fixed its alot easier when searching for a suitable software
How accurate is the ink/toner meter in the HP printer toolkit (hplip-gui)? The meter says my toner level is "good/ok" and displays a black bar with tick marks, but I'm skeptical of its accuracy. I bought this Laserjet P1006 last January, with a starter cartridge of toner that was rated for around 120 pages (if I recall), and have printed occasionally. I'm afraid of running out of toner right when I need to print something important and time-sensitive. Since it doesn't appear to be possible to look inside the toner cartridge (sorry, this is my first laser printer ), I can't do anything except hope the HP toolbox measures my toner level accurately.
When someone is speaking into the mic, I'd like a "level meter" such as the one that comes with gnome sound recorder, that flashes up and down when a sound is made or somebody talks.This will be done in Javascript, using the brand new "Rainbow API", i.e. inside the browser.I know nothing about audio programming, so - where would I get *started* with something like this? Could anyone tell me at least WHAT to Google?
I find xcompmgr more than adequate for making a desktop look pretty modern, and I don't like the more extravagentCompiz gimmicks - but there is one thing that irritates when using xcompmgr which someone here might have worked round.
Rounded window borders don't draw and redraw properly when using the Terminal (gnome-terminal and the LXDE and Xfce ones) or system monitor and moving them from their default place. You get this little white botch at the corners. I'm not massively technical and I'm ambivalent about how much more I want to learn as I have plenty of creative outlets already, but I would like to solve this. Somehow xcompmgr is treating these programs as a different class? It's capable of drawing the window borders properly as it is just these two programs that get botched. Possibly this doesn't get noticed as maybe people usually use xcompmgr with openbox and LXDE and their square window borders. I did do a search but there was nothing matching what I saw.
How does the Battery Power Meter works.As I know that the APCI is control by software.so my question is the battery connected also to other place on the board and send signal for how much power left.or every motherboard that have APCI "Enabled" can recognize only from the DC power connector how much left. if yes, in what why it recognized.
I've been tooling around with Fedora with the Fluxbox environment on my old Dell 400SD4 laptop and it works fantastic. I'm still getting a feel for the environment, but one major concern that I had was a battery meter. Being a laptop, it's important to know when I'm almost out of juice. Does anyone have any suggestions for a battery meter for Fluxbox? Preferably one that can be installed through the yum repositories?
I recently installed Ubuntu 10.10 Desktop Edition on my HP Compaq Presario V3018TU Note Book PC.It is working fine. The problem is with Power Meter.It shows battery Charged in Icon, though it is discharging. Also after clicking on it, it should show % battery power. But it only shows (estimating).Is there any way to fix this ?It was working fine with Ubuntu 10.04.
Does anyone one know of a free broadband usage meter for linux which will record the amount of uploads and downloads on the netwrok and alert you when the limit has reached? I was using TB meter on windows Vista.
I am trying to convert movies to mpeg4 or more specifically formatted to play on my blackberry curve. I followed installation guide from this tutorial [URL]. Everything installed and the program works but when I add a file and pick presets and hit convert the terminal pops up and says the following:
[Code].....
So I press Enter and the terminal closes, than... nothing happens just staring at the winff screen.
I really have no idea where to go with this. I found a link from the forums earlier on these common crashes but cant seem to find it again.
I want to use Kazam Screencaster to record my vids, but it goes to the tray when you record, and I don't use a panel (my desktop is the very definition of minimalistic. I just use all shortcuts and terminal.)
is there any way I can record/stop it with the terminal?
is it possible to rip a Video DVD to hdd with a command line command ? Or with a bash script. What I want it to do is to rip the Video DVD as is in VIDEO_TS structure to the HDD. No encoding to other formats.
I'm trying to write a script that opens up vlc, opens up the playlist, and then opens up my music folder. So thus it looks like this so far;
Code: #!/bin/bash
vlc & # command to open up vlc playlist gnome-open /media/files/multimedia/music However, I seem to have no clue as to how to open vlc's playlist from a command. I know the hotkey for opening the playlist is "ctrl + L" but I don't know if this is useful at all.
My terminal program comes up as a white screen (see Screen shot picture)and so does the login screen (Like when you run updates and it asks you to log in so you can update, YES that screen) I have searched and found nothing on this
I have a Dell Optiplex GX115 Dell LED flat screen 49T monitor Ubuntu 9.10 512mb ram 80gb hard drive
I was having issues with xscreensaver, desktop background and VLC all cutting out at same or different times and narrowed it down to "possibly" compiz or the FGLXR ATI driver that was recommended for my ATI HD3200 card. So, without knowing better, i went into hardware settings and removed the proprietary driver and did a reboot thinking the system would come back up and default back to a vanilla driver. No dice. Hello white screen of death! So, i am assuming that I can just reinstall via terminal and life will be good again? So, looking for CLI commands via terminal for reinstall.. (if possible)
