我认为最简单的方法是加入远程 shell。只需使用 -remsh Node
参数启动 erl
即可。
$ erl -sname foo
Erlang R13B04 (erts-5.7.5) [source] [smp:2:2] [rq:2] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.7.5 (abort with ^G)
(foo@hynek-notebook)1>
另一个终端:
$ erl -sname bar -remsh 'foo@hynek-notebook'
Erlang R13B04 (erts-5.7.5) [source] [smp:2:2] [rq:2] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.7.5 (abort with ^G)
(foo@hynek-notebook)1>
另一个选项是使用
erl
的强大作业控制功能(按下
^G
)。
$ erl -sname bar
Erlang R13B04 (erts-5.7.5) [source] [smp:2:2] [rq:2] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.7.5 (abort with ^G)
(bar@hynek-notebook)1>
User switch command
--> h
c [nn] - connect to job
i [nn] - interrupt job
k [nn] - kill job
j - list all jobs
s [shell] - start local shell
r [node [shell]] - start remote shell
q - quit erlang
? | h - this message
--> r 'foo@hynek-notebook'
--> j
1 {shell,start,[init]}
2* {'foo@hynek-notebook',shell,start,[]}
--> c
Eshell V5.7.5 (abort with ^G)
(foo@hynek-notebook)1>
User switch command
--> j
1 {shell,start,[init]}
2* {'foo@hynek-notebook',shell,start,[]}
--> c 1
(bar@hynek-notebook)1>
请注意,如果您要切换回现有的Shell提示符,请按
Enter
键以显示它。这一点需要记住。
