Copy file to a Windows/Samba share without mounting it
This commando copies the file (which must reside in the current directory) to //<server>/<share-name>/<subdirectory>/<file> through the CIFS protocol (Samba share or Windows Share). It doesn't require you to mount the filesystem first. --directory "<subdirectory>" may be omitted in order to copy the file the the root of the share. The "%password" part may also be omitted. If doing so, smbclient will ask for the password interactively. To copy a file from a Windows/Samba share, change "put" for "get". $ smbclient --user=user%password --directory "<subdirectory>" --command "get <file>" //<server>/<share-name>
