That was a sweet bit of code, I have scripted some in bash= and thats
maybe why the looks like it does :) .

But I have applied the "ruby" style to the code as you suggested = and it
works good for this part:
cmd.each do |c|

=A0 command1 =3D IO.popen(["plink.exe", "-= P", port.to_s, "-pw", pw,

"#{user}@#{ip}", c]) {|io| io.each {|line= |}}
end

so beautiful simple.

but when I get to the part where I want to download the files I get
stuck:
output.each do |f|
=A0 download =3D IO.popen(["pscp.exe", "-P", port.to_s,= "-pw", pw,
"#{user}@#{ip}:f"]) {|io| io.each {|line|}}
=A0 puts f
=A0 puts download
end

I have modified it a bit to see what values I have in the variables, but the output is abit strange:
If1.cap
#<IO:0x2845d70>
If2.cap
#<IO:0x28456f8>

I store output in a array, so I wounder is a array item always
surrounded by [item]? Is it possible to show the download in another
format not IO:0x..... more like the actual command?

Well, you can use

{|io| io.read}

instead of

{|io| io.each {|line|}}

but that will o= nly give you the output from pscp. =A0And apparently that contains [] becau= se it's an error message. =A0You probably want to look at the other var= iants of popen to properly evaluate the result code of the external command= and react appropriately.
