permissions to /var /usr

hi guys

I had 10 users and 3 linux servers
they are normal users

I need to assign read access to these 1o users to /opt /var /usr and all files and folder withing them

how can I accomplish that without going user by user?


any idea?

should this command work? well for me is not working

Code:

chmod -R o+r /var/*

is that command OK?

 

I think

Code:

chmod -R o+r /var

should be enough.

 

well I think I need it on /var /usr

do you think is a good idea? provide read permissions to all folders and files with those 2?

thanks

 

i just found is not a good practice AT ALL

 

A safer way would be to create a group for these 10 users and then give read permissions to just that group.
