Dump erlang's beam files to filesystem

Question

I have a remsh to working Erlang application:

1> application:which_applications().
[{ssl,"Erlang/OTP SSL application","5.3.6"},
 {public_key,"Public key infrastructure","0.22.1"},
 {crypto,"CRYPTO","3.4.1"},
 {asn1,"The Erlang ASN1 compiler version 3.0.2","3.0.2"},
 {stdlib,"ERTS  CXC 138 10","2.2"},
 {kernel,"ERTS  CXC 138 10","3.0.3"}]

My question is: How can I save beam files to another place at the file system?

Answer 1

For each module you want to save, call code:get_object_code/1 to get the module's object code as a binary, then use file:write_file/2 to save that binary to the file system.
