fcopy使用tcl将文件从主机复制到vm

Question

i want to use tcl command fcopy to copy a file from windows host machine to a vm location. What I get is I need a inchannel and a outchannel. Here inchannel in the filestream and out channel is some kind of socket where a server is runing maybe. I am at bay regarding the server part and how the file will be saved from the socket in a vm path. Please guide with some resource link.

If you have two filenames (and both are currently visible, which depends on how things are mounted and which is totally out of baseline Tcl's control) use file copy . Otherwise, if you can arrange to get the contents of the file somehow (perhaps by using ssh hostaddress cat ) then you use chan copy (which fcopy is the old name for).

set srcFD [open |[list ssh hostaddress cat "src/file.ext"] "r"]
set dstFD [open "dst/file.ext" "w"]

chan copy $srcFD $dstFD;    # Or: fcopy $srcFD $dstFD

close $srcFD
close $dstFD
