Erlang Shell下有很多内置的命令，在平时交互的时候很好用，文档里面都是一行带过，大家可能没什么感觉。
我来重点讲解和演示下：
Erlang R14B04 (erts-5.8.5) [source][/source][/source] [smp:2:2] [rq:2] [async-threads:0] [hipe] [kernel-poll:false] |
Eshell V5.8.5 (abort with ^G) |
** shell internal commands ** |
b() -- display all variable bindings |
e(N) -- repeat the expression in query <N> |
f() -- forget all variable bindings |
f(X) -- forget the binding of variable X |
history(N) -- set how many previous commands to keep |
results(N) -- set how many previous command results to keep |
catch_exception(B) -- how exceptions are handled |
v(N) -- use the value of query <N> |
rd(R,D) -- define a record |
rf() -- remove all record information |
rf(R) -- remove record information about R |
rl() -- display all record information |
rl(R) -- display record information about R |
rp(Term) -- display Term using the shell's record information |
