Preserve the permissions with rsync
Let’s say I have a file a.txt in LINUX with permission of 0664.
When I use rsync to copy the file to my Mac with rsync -r -t -v LINUX MAC, the file’s permission becomes 0644.

How does umask affect ACLs?
Can someone explain to me how umask affects the default mask of newly created files if ACLs are activated? Is there some documentation about this?
One file wants to belong to two users. How? Hard linking fails
Two setuid programs, /usr/bin/bar and /usr/bin/baz, share a single configuration file foo. The configuration file’s mode is 0640, for it holds sensitive information. The one program runs as bar:bar (that is, as user bar, group bar); the other as baz:baz. Changing users is not an option, and even changing groups would not be preferable.
Can users in a group access a file that is in another user’s home directory?
I have 3 users A,B and C inside a group ‘admin’. I have another user ‘D‘ in whose home directory, there is a project folder. I have made D as the owner of that folder and assigned ‘admin’ as the group using chgrp. Group and owners have all the permissions, but still A,B or C are unable to access the folder. I have two question :
How to change folder permissions during package installation
I’m making a deb package to install a custom application. I changed all files/folders ownership to root in order to avoid the warnings I was getting during installation, and in Ubuntu all runs smoothly, as Ubuntu changes the ownership of the files/folders to the user installing the package.
Which user group can use the ‘tap’ net device?
I use the ‘tap’ net device with KVM to get my vm connect to the Internet. But I have to be root, or use ‘sudo’, which is inconvenient. I think I can put my user account into some group so I can access the net device without root privilege. I tried the netdev group, but does not work. My account is already in the kvm group.
Proper way to set the umask for SFTP transactions?
My goal is to allow all users who are members of the “team” group to edit (r/w) the same set of remote files — normal work collaboration — using a local mount point. I have tried NFS and SSHFS using ACLs without success yet. Here I am trying to get SSHFS working by making the umask correct (which, in theory, should solve the problems I’m experiencing).
Make all files under a directory read-only without changing permissions?
First, some background:
sudoedit root owned file in a non-root directory
Why can’t I edit files owned by root but being e.g. somewhere deep in my personal directory, it says:
How to set file permissions with touch command
It seems that whenever I create a file with touch the permissions are set to: -rw-r–r–.
