Re: output from sage to file

[P Purkayastha]

The sage prompt is *not* a bash (or shell) prompt! It is an ipython
prompt. If you want the output dumped to a file, then you need to run
the asd.sage file like this:

$ sage asd.sage > output.txt

I understood. Then next question.
I build sage from source.
In terminal.

$ sage
No command 'sage' found, did you mean:
 Command 'osage' from package 'graphviz' (main)
 Command 'save' from package 'atfs' (universe)
 Command 'page' from package 'tcllib' (universe)
sage: command not found

Best regards,

Aleksandr

Hi

Your sage installation seems to be in /home/toivo/sage/.
This is normally called SAGE_ROOT, which is a bash variable.
You can set the command sage to be an alias for /home/toivo/sage/sage
like this

alias sage='/home/toivo/sage/sage'

and you can make this permanent for all new terminals you open by
adding that line to your /home/toivo/.bashrc file, the configuration file
for bash.

Regards,
Jan

Best regards,

Aleksandr
