General :: Concatenate And Labeling Files ?
May 5, 2010I have an assignment question that I have been making no progress on.
I need a single line command to concatenate a group of files together and clearly label those files in the output.
I assume that just cramming a bunch of commands onto one line will not be considered OK.
and it has to work on some old version of Solaris (which I have been having trouble with normal commands not working the same all day on), but if you just have solutions for any normal Linux shell at least I would have an idea of what I am looking for.
I have looked though cat's man page up and down and I am pretty sure it cannot do what I want, and cannot seem to find any other commands that even concatenate a grouping of files together.

General :: Possible To Concatenate *.flv Flash Video Files?
Oct 12, 2010Have got a film broken up into 10 minute chunks a la ...... Tried cat file1.flv file2.flv > file1&2.flv but mplayer stopped, saying 'end of file', half way through playing file1&2.flv.
Is there some way to join them together into one, so the film may be played all the way through.
Just occurred to me you could use an * for the counting numeral in the filename e.g. mplayer file*.flv for file1.flv, file2.flv, etc..

General :: Using Underscore In File Names?
Apr 4, 2011I use the command line frequently to navigate my files so I try not to have spaces in file names.

Are there any disadvantages to using an underscore in file names?Should I switch to a dash? My system is running Xubuntu and I almost exclusively use the bash shell.

May 6, 2010Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up).

General :: Concatenate Several Images Into A PDF File With Several Images Per Page
May 2, 2011I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:

The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.

Ubuntu :: Blinking Underscore While Booting?
May 14, 2011My parents just upgraded from their 8+ year old desktop to a newer dell. The old one has XP on it and would barely run, lots of bloatware, viruses, etc.. I tried putting an ubuntu 10.10 disc to boot from it but the old desktop suddenly stopped recognizing mouse and keyboard input so I couldn't change the boot preferences. I took the hard drive out and plugged it into my desktop, copied all the useful files to my hard drive, then wiped it. I then installed ubuntu on the old -and now empty- hard drive by having it plugged into my computer.
I put the hard drive back in the old desktop and found that the keyboard now works. I can press F2 or F12 and change things around and whatnot. However, when I let it pass the screen that prompts me to press F2 or F12, it goes to a screen with a blinking underscore in the top left of the screen and gets stuck there.
what's causing it to get stuck on this screen?

General :: Setting Up Variables (in RDGEN)
Jan 17, 2010I have installed RDGEN which comes with VPFIT package. When I run the program it says:
"Failed to find help file"
But I ran the program from its main directory where all the files including help files exist. I think maybe the problem is because of this that THEY say:
"Some environment variables should be set before starting RDGEN".
But I do not know what does this mean and how to do that.
These are the variables:
-ATOMDIR
-RD PRSETUP
-RD PRSETUP
-RDSTART
-VPFSETUP
-VPFPLOTS
Would it be possible for you to tell me what does Setting Variable means in this case?
