Something has come up which demands me to work only in command line. My primary job is programming (mostly in Fortran and Octave) and I need to display plots.As a lame example:I open octave and type ezplot('sin(x)')and it outputs that X11 Display Environment not set and unable to open display. Is there any way for me to view graphics in TTY?Obviously, I don't expect awesome graphics but I need to see if I am on the right track once a while.My current algorithm is extremely inefficient. I print -djpeg foo.jpeg and then scp it to my neighboring computer. Borrow that and continue. 
Graphics in TTY

If you simply have a series of .jpeg images that you wish to display in a tty, you can use aview or asciiview. When calling asciiview with an image, it will convert the image to the .pnm format - using an external program like NetPBM or ImageMagic - before passing it to aview for displaying. The .pnm is the ascii image format used to represent the image as set of characters. To view an image in this format, simply use:$ asciiview foo.jpegor to save a .pnm copy first:$ convert foo.jpeg foo.pnm$ aview foo.pnmThese support the driver from aalib.
