Sim, é. Pelo menos para o tar GNU, a documentação diz:
If the archive file name includes a colon (
:
), then it is assumed to be a file on another machine. If the archive file isuser@host:file
, then file is used on the host host. The remote host is accessed using the rsh program, with a username of user. If the username is omitted (along with the@
sign), then your user name will be used. (This is the normal rsh behavior.).
Também fornece uma solução alternativa:
--force-local
Archive file is local even if it has a colon.
