I have a new user masi in Raspbian Jessie. I want that it has access to /usr/bin/ etc wget. I didsudo adduser masi     sudo visudoroot    ALL=(ALL:ALL) ALLmasi    ALL= NOPASSWD: ALL % passwordless root accesssu masipasswdAs masi, I cannot do wget getting Permission denied, only as sudo wget now. The command ls -la /usr/bin/ gives user/group as root:root for all commands which is the problem. I think I should have root:wheel. I think this can be done by groupadd wheelsudo usermod -a -G wheel masisudo chown root:wheel /usr/bin/*I took the groupname wheel from my OS X. I am not sure if it is the right convention here for naming. I do not understand how Raspbian Jessie has beed designed. I only understand little Ubuntu. I think the commands may not be sufficient because the thing is changing only one directory. I am setting up owncloud server with PostgeSQL-9.4 in Raspian as described here for older version.How can you add a new user with sufficient righs for wget and others in working folders /usr/bin/ ... in Raspbian? 
To wget as New User without sudo in Raspbian
permissions;sudo;raspbian
You able to setsudo chmod +x /usr/bin/*It's a little strangely that files in bin are not executable be default.For example in my ubuntu:$ ls -la /usr/bin/...rwxr-xr-x  1 root root         14768  15 01:19 zdump-rwxr-xr-x  1 root root         10384  31 02:14 zeisstopnm-rwxr-xr-x  1 root root        206000  24 17:31 zeitgeist-daemon-rwxr-xr-x  1 root root        131760  24 17:31 zeitgeist-datahub-rwxr-xr-x  1 root root        105752  16 18:30 zenity...
