Re^2: setting file permissions through sftp

[gman]

I am still not understanding the relationship between what Net::SFTP::Attributes ( 'perm' => 33092, ) and unix style file permissions? Am I missing something obvious?

You have to convert the value to octal representation, e.g.

my $perm = 33092;

printf "%o\n", $perm & 07777;   # prints 504

Also, to set the permissions, you probably want $attrs->perm( 0777 ), not $attrs->perm( [ '0777' ] ). The square brackets in the docs mean optional, i.e. you'd specify nothing to retrieve the value (combined 'setter' and 'getter' method...).

Update: forgot to mention the '& 07777' above masks off the four octal groups of interest here, i.e. three times rwx (for user/group/other), plus the SUID/SGID/sticky octal group (the latter is the first (leftmost) one).

Thank you! I would say that falls under the obvious :)

And especially thanks for the update on the '& 07777' explanation.

Thanks, Cory
