'tcsh' should be irrelevant here -- it is so different than 'sh' that
no sane distribution would try to give you 'tsch' when you want '/bin/sh'.
AFAIK some Linux distributions use 'ash' as a default Bourne shell
and maybe you hit its incompatibility with 'bash'. However, IIUC
'ash' is claimed to be POSIX compliant and POSIX includes quite
rich functionality for redirections. FriCAS build on Solaris
currently insits on 'bash' because default '/bin/sh' on Solaris
is an ancient pre-standard version.
I took a quick look at fricas-run and AFAICS the redirection part
should work on all Bourne shells. If you do not get Bourne shell
than you probably use wrong emacs function (or wrong option to
this function) -- emacs developers know well that commands for
Bourne shell do not work with C shell (like tcsh).
As a brute-force solution you may try adding
SHELL=/bin/sh
export SHELL
to efricas script.
