See and access sage-5.10 folder but get no "such file or directory" message
I have installed sage-5.10 in my laptop with Ubuntu 13.04. The folder with sage-5.10 is there, clicking in the folder I can see all the folders and files inside it on any level. Have being using a worksheet for a while with some calculations. I start my sage worksheet in my terminal changing directory
cd /home/alien/Desktop/Sage/sage-5.10
then
./sage
then
notebook()
But suddenly when making the cd /home/alien/Desktop/Sage/sage-5.10 I'm getting the message "No such file or directory". So can't start again sage and using my worksheet. How can I solve this problem?.
I'm just curious why Sage 5.10; is this because your Ubuntu is five years old? In any case, this certainly could work if Sage lives in that directory; however, is it possible you removed it with an update?
About four or five years ago I decided to free myself from Mathematica and sage was my best option. Installed sage in my Ubuntu and began to do some calculations related to my research in mathematics. A little complicated period of my life began too and I had to forget my calculations for e few years. Now I finally can continue my research, this explains why sage 5.10. As far as I remember I never did an update, the directory is there, I can see every thing inside the folder.
I see, that is reasonable. But we'd have to know more about this to know why you can't get in this directory - it seems like more of a Linux issue than a Sage issue so far. What happens if you do
ls /home/alien/Desktop/Sage/sage-5.10? If that works, then so should changing into that directory ...
