Copy to clipboard using Bash for Windows
In Build 14393 or later, if you want to copy something to clipboard in WSL console, just add '.exe' to what you do in Windows cmd.
echo "aaa"|clip.exe
To read from clipboard:
powershell.exe -command "Get-Clipboard"
In order to copy non-ascii characters (other languages), I had to do this:
echo 'αβψδεφγ' | iconv -f utf-8 -t utf-16le | clip.exe
utf-16le excludes the preceeding BOM so you can paste it back
This still does not seem to be supported: (https://www.reddit.com/r/Windows10/comments/4gwnom/can_bash_on_windows_interact_with_the_system/)
A clever workaround is the open source tool plak (https://github.com/sander/plak)
