See the ITS-Supported Computer Lab page. These computers will have both secureCRT for connecting to Galileo and the (Hummingbird) Exceed X-Server. Just start X-server (the Exceed program) and connect to Galileo using the secureCRT program. If you get an error trying to display X windows, open the configuration for secureCRT and enable X11 tunneling. Then exit and restart secureCRT.
See the documentation at the bottom of the Labs Page.
Use the wget command from your Galileo account. For example to copy the data file from homework 1, give the link to the data file to wget (you can copy a link location with your mouse by right clicking on the link):
This will copy the file young.dat to your current directory on Galileo.
1) One choice for printing is to transfer your files to your UVa Webmail or your home PC. See the Homework Page for instructions.
2) You may print directly from galileo as follows:
lpr -P physics_323@print <filename>
This will send your file to the printer in Room 323. You must use your Cavalier card to claim the job at the printer before your print job will complete. To make this your default printer add the following line to you .login file in your home directory:
setenv PRINTER physics_323@print
Then you can simply type:
to send your print job to the library.
3) This option is probably useful to the T.A.'s only. If you have a copier account with the physics department you can use the department printers. The codes are the same codes you use for the photocopier. If you are logged in under your official UVA user ID when you submit the print job, the billing system will automatically send you an e-mail message reminding you that you have an unclaimed job waiting in the queue. This message will also give you the address of the web page you should visit to claim the job. If you do not receive an e-mail message, you'll need to point your web browser at the following address to claim the job: https://print.phys.virginia.edu/claim/
|print commands for Physics Department printers|

|room 100 BW printer||lpr -P physics_100@print|
Yes. Just set gnuplot to output to a graphics file:
gnuplot> set term pdf gnuplot> set output "outfile.pdf" gnuplot> your plot command here gnuplot> quit
pdf files: ps2pdf filename.ps # creates filename.pdf jpg file: mogrify -density 120 -format jpg filename.ps png file: mogrify -density 120 -format png filename.ps
The density setting specifies how many pixels to use per inch when translating your postscript document. Higher densities will generate larger and more detailed bitmapped graphics. Note: gnuplot can also output directly to a png file using the setting set term png
gnuplot has the ability to make animated plots from your data files. If your data are divided into different sections separated by two blank lines in your file, gnuplot can make an animated display by successively plotting the different data sections. To create an animated gif graphic of your individual frames (png or jpg files for example) follow these steps:
(1)type: convert -delay 20 snap*.png anim.gif optimize the file: (2)type: gifsicle -O anim.gif > anim2.gif delete the original giff file -it's big! (3)rm anim.gif
you can view the result in a web browser or by using the program:
see man gifsicle / gifview for more information
The GNU acronym stands for Gnu's not Unix. It's pronounced: “guh noo”. You can learn about the GNU Project from their website at www.gnu.org. Here you can also learn about the history of modern free (as in freedom) and open source software efforts and the GNU/Linux relationship.
Having trouble w/ delete on certain terminals when using emacs? Make a file called .emacs in your home directory, and include the following lines. This will setup your Backspace key to delete a character to the left of the cursor.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; These two commands let you use Backspace ;; (Ctrl-h) as Delete in emacs. ;; The second one sets M-h (Esc h) to be the ;; help key. ;; Copy this four-line block unchanged to the ;; end of your .emacs file ;; Translate C-h to DEL (keyboard-translate ?\C-h ?\C-?) ;; Define M-h to help ;; don't add an extra ' after help! (global-set-key "\M-h" 'help) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
