G'day vinoth.ree,

I have Windows 10. I have an oldish ActivePerl (5.16.3) but not as old as your 5.8.8. I also have:

C:\Users\ken>dir C:\Windows\System32\OpenSSH\scp.exe
...
19-Mar-19  17:19           322,560 scp.exe
...
[download]

Locally, I created D:\tmp\sample.dat: it just contains the string "This is sample data."

Remotely, I checked for ~/tmp/sample.dat: not found.

Locally, I ran (via cmd.exe):

C:\Users\ken>perl -e "my $cmd = qq{C:\\Windows\\System32\\OpenSSH\\scp
+.exe D:\\tmp\\sample.dat W\@X.Y.Z:/A/B/C/tmp/sample.dat}; qx{$cmd}"
Password:

C:\Users\ken>
[download]

Remotely, I now have ~/tmp/sample.dat which just contains the string "This is sample data."

Because the remote machine is a $work computer, I was somewhat loathe to publish details. You can probably work out: W is my username; X.Y.Z is the URL; and, /A/B/C/tmp is ~/tmp.

Hopefully, if you use the same "\\", "\" and "/" combinations as I did, your scp will work.
