File Permissions on Ubuntu (umask)

  • 772

I want to make all folders in a directory chmod to 755 and individual files to chmod 644. Is there a way I can use umask (e.g. umask 022) to specify these permissions in the future?

Thanks in advance.

  1. find ~ -type d -exec chmod 755 {} \;
find ~ -type f -exec chmod 644 {} \;

echo umask 0022 > ~/.bashrc # [ this should be in your /etc/profile* already ]

  2. You can solve this then using access control lists. man setaclf

    Aside from this and or making a cron script that occasionally goes through and makes sure that everything is chmodded correctly in this directory there is no elegant way to go about this in linux.

    • Caveat with acl's, all files created in that directory would have the proper umask applied but any files copied over would have to be chmodded or as stated before you can have a recursive cron script that chmod's the entire directory
