bash: sage: command not found

[Felipe Torres]

I recently installed sage on a server and it works because when I go to /usr/local/sage I run ./sage and it runs, but if I want to use it to compile a sage based file it says:

bash: sage: command not found

[root@localhost sage]$ sage
bash: sage: command not found
[root@localhost sage]$ ./sage

Can anyone tell me how can I run sage to compile or run a file, if I need to configure something or install something else?

Hi

Try

sudo ln -s /usr/local/sage/sage /usr/local/bin/sage

amd them run sage again.

Regards,
Jan

Short version:

Try running
export PATH=$PATH:/path/to/your/sage/program
and try again.

Longer version:

Bash does not find the sage executable because it is not in the PATH. By
adding the path to the sage program to your PATH, bash will know how to
find it. In my case sage is in "/home/johan/Applications/":

johan@johan-laptop:~/Applications$ sage

bash: sage: command not found

johan@johan-laptop:~/Applications$ ./sage
