One way is to use a pipe (assuming UNIX here):

$ echo "erlang:now()." | erl -boot start_clean
Eshell V4.9.1  (abort with ^G)
1> {948,985137,921298}
** Terminating erlang **

Or using erl_call:

# erl_call -s -sname foo -a 'erlang now []'
{948,985627,609986}#

# setenv X `erl_call -sname foo -a 'erlang now []'`
# echo $X
948 985713 596695
# erl_call -sname foo -q
# erl_call -sname foo -a 'erlang now []'
<ERROR> erl_connect failed


erl_call --help for detailed instructions
