OK, I didn't realise that math-readline was a Python script from Sage.

I created https://trac.sagemath.org/ticket/23112 to track this issue.

Same for me as for John: after

sage -sh
math-readline
/bin/sh: 1: math: not found

the sage shell is not displaying what I am typing.

and even the bash shell itself is in the same not-displaying mode.

I tried this.  First time it did actually start up Mathematica which
was a surprise since I did not know that my office desktop had
Mathematica on it...
On a machine which certainly does not, I got the message expected
(sage-sh) jec@lehner:sextics$ math-readline
/bin/sh: 1: math: not found

*but* after that the terminal was in a weird state, not echoing input,
which I got out of by blindly typing "exit" which got me out of the
Sage shell.

Conclusion: even when there is no Mathematica something non-trivial
and possibly bad is happening.

Define "fails immediately". The fact that it only "fails immediately" 19 
out of 20 times means that the "fails immediately" is somehow non-trivial.

[sage-release] Re: Sage 8.0.beta8 released

[John H Palmieri]

I'm getting intermittent timeouts from src/sage/doctest/external.py, and in 
particular the "has_mathematica()" test. This is a new (but underpowered) 
computer and it does not have mathematica installed. If I run

   $ sage --sh
   $ math-readline

then 19 out of 20 times, it fails immediately, but every now and then, 
maybe when the computer is more heavily loaded, it does something else: it 
says

   /bin/sh: math: command not found

(as with the immediate failures) and then it waits for input. This must be 
what is causing the timeout in the doctest. If I hit RET, I get the shell 
prompt back. Why is it waiting for input when the "math" process failed? 
Any suggestions for how I could diagnose what's going on?

  John
