No; rsync splits the command at space characters without observing any
of the more sophisticated conventions, such as quoting or escaping, that
shells do. Here's the relevant excerpt from rsync/main.c :
static pid_t do_cmd(char *cmd, char *machine, char *user, char
*path,
int *f_in, int *f_out)
{
[...]
for (tok = strtok(cmd, " "); tok; tok =
strtok(NULL, " ")) {
/* Comparison leaves rooms for
server_options(). */
if (argc >= MAX_ARGS - MAX_SERVER_ARGS)
{
rprintf(FERROR, "internal:
args[] overflowed in do_cmd()\n");
exit_cleanup(RERR_SYNTAX);
}
args[argc++] = tok;
}
[...]
}
And strtok just looks for occurrences of the indicated character(s) --
here spaces.
