Is it possible to send data to stdin of the called command in erlang?

Question

Erlang

If you call a system utility from erlang via erlang.org/doc/man/os.html#cmd-1 , is it possible, and how, to submit data to its input? Let's say I want to call the iconv utility by supplying utf8 to it, and with stdout I want to get windows-1251. Maybe?

Answer 1

is it ?
If pipes are not supported under windows, then wrap the call in a wrapper from the cmd /c command 'command < windows pipe or file > resulting file 'and use regular system pipes or temporary files
