I have an sftp-server and need to set all files' permissions to 775 which upload from client.How can I do that? Just found the umask set,but it is not fit for me as client may upload file with 664 permissions.

"but it is not fit for me as client may upload file with 664 permissions." --> what do you mean?– quantaOct 7, 2011 at 7:00

umask just help you mask the client upload files' permissions like (0777 -> umask 0022 -> 0755).– frankyueOct 7, 2011 at 7:04

And how can I set to make all files to 775 whatever the client upload?
You cannot.
Resulting permission = Default permission AND (NOT umask)
With file:
default permission = 666 = 110 110 110
umask = whatever
resulting permission = xx0 xx0 xx0
In summary, you cannot create an executable file using umask.
