Ubuntu Multimedia :: Terminal Command In Script To Save File
Sep 28, 2010
I use webcam with the streamer application. So, to record a video I have to put in terminal something like this:
Code:
streamer -q -c /dev/video0 -f rgb24 -r 24 -t 00:30:00 -o /home/shark/untitled.avi
I know I can use other applications but I have got problems with all except with this. This is really annoying because it is a delay job. So, I am wondering how can I make a script that the terminal will ask me to name the file or even better to ask where to put my file.
I sometimes stick my neck out and provide somewhat detailed, and often risky, "Mr-fix-it" remedies for boot problems. Now, I know it's possible to amend each command with "whatever_command > whatever.txt" in which case it'll place the command output in a file in /home.
But if you're directing someone to run a lot of commands as I did here is it possible to save the output of all commands to a .txt file without amending each command?
Or is it already saved somewhere that I'm not yet aware of? I wouldn't be surprised if the latter were true, I just haven't yet found it
is there a Terminal command to open a Target file (same as the one opens when you want to upload a file), let user choose the file and when he clicks open, be able to save his choice?for example:echo "Choose source file"--> command needed to browseand then open or save path to that file
How do I save it as a jpg somewhere on my puter using a script? I can wget, but it gets saved as a .evif, which is totally useless. I can right-click on the image in a browser and use the context menu to save it as a jpg, but I want this process automated. How can I DL this image and save it as a jpg? GIMP's CL options don't include the capacity to save/convert this image, though it's possible from teh GUI. ImageMagick won't read this dynamic URL. What do I do?
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
Well i downloaded a program with many .deb files ( At least 15 ) so i wanna execute them all trough the terminal so i typed
Code: patowlmc@patowlmc-desktop:~$ cd /home/patowlmc/Downloads/i386 patowlmc@patowlmc-desktop:~/Downloads/i386$ sudo dpkg -i *.deb Readme.deb: command not found
As you can see all files in the folder are .deb packages, but one: The Readme file, wich is a text file.
I know I just have to move the file to somewhere else, and everything should work, but i wanna know if there's a command for excluding a file or something.
P.D. I totally trust the program, so don't worry about so many .deb files.
is there a way to pipe a video feed from virtual box to vlc and save it as a file? cause if i could then i could save streaming videos from places like hulu and netflix or save bluray movies to a avi file for latter use.
How do I use my SSH Terminal to get a file that is sittng on another server that I have.. As its like 500 megs or so but to download it to my computer then upload it it takes a long time..
So this is what i have done so far
1. Loged in to SSH Terminal
2. Went to my DIR that i want to put the FILE to
3. Typed in FTP
4. I"M LOST now as i'm trying to connect using my user on my ftp site (DIFFERN"T SERVER)
I relly need the key commands SHH Terminal for dummies
Have been having some problems with Libreoffice Writer crashing every time I try to save a file that contains any kind of multimedia (usually images) so I decided to completely remove the app and any trace of it and start again.
After complete removal I reinstalled from the Opensuse repo 3.3.1
The porblem I have now is that when I start typing in writer absolutely nothing happens. Wait approximately one minute and the text I typed appears. Try to backspac to delete or type some more and the behaviour persists.
simple scan error as follows: Failed to save file ImageMagick returned error code 11 Command line: convert -adjoin /tmp/simple-scan-DA9MBV.jpg /tmp/simple-scan-XCK4BV.jpg /tmp/simple-scan-NZVYBV.pdf Stdout: Stderr: using karmic note: I have apparmor extra profiles installed but didn't notice one that related to simple scan or imagemagick. Red herring or not?
there is any way (via terminal or gediting a file) to use .flac files instead of .ogg in a sound theme file? I am creating a sound theme (several truthfully) and I would like to use the FLAC format if possible.
I need a hand with a line of terminal commands. I need to be able to search a given .sh file in a given location for a string, and when found, add a "#" to the start of that string and save the file back to it's original location.
I've recently installed matlab and after some poking around found that you must start it using a script like:
#>> cd ~root/../matlab2009/bin/ #>>./matlab
the manual tells me that the installation should have made it so that all you have to do is type matlab at the terminal but for some reason this hasn't happened. If you did not set up symbolic links in the installation procedure, you must enter the full path name to start MATLAB, matlabroot/bin/matlab, where matlabroot is the name of the folder in which you installed MATLAB. I've also looked at documentation on ln but most refers to making links between files. Is there a way to link the command "matlab" to the file shown above so all I have to do is type the command and it runs the script?
I'm looking for a way to have the access log for my nginx install scroll up the terminal as lines are added to the log. I think I need a command like cat access.log | diff but I'm not sure exactly what it should be.
is it possible to log the command output's history that are previously printed messages in the terminal to a file? that is the first command output when i first opened terminal through the last command.
I've got used to using the ftp command from the terminal, which is useful, especially with macros. But it requires user input, and what I want to do now is upload a specific file to a server, once I've finished working with it every day. It's the same file every day. II would like to be able to do this semi-automatically: I just give the command and it connects to the server and uploads the file. (I will probably want to encrypt the file before uploading it.)I don't know how I could use ftp without any user input: I want it to be automatic.
Now, I use Fedora Core (version 8) with core linux OS 2.6 I have some file data with size about 2G and I want to burn (write) this file to DVD rewrite.
I know linux OS can install software to burn data to DVD, but I don't have permission to install more software. I only use command line over Terminal (Gnome Terminal).
Out of X I have auto-completion for a command parameter (e.g. 'aptitude upd(ate)') but in gnome-terminal I have auto-completion only for the command, not for its parameters. Is it possible to have that?
In terminal, I use the command " export XXX="xxx" " to create a new environment variable, and then " env | grep XXX " to check if it is existed. But when I run the terminal again, the variable I created is disappeared. I've found it just can't save the variables I created..
