linux permissions basics tutorials

  • The UMASK value masks out the bits. The permissions that each position in the UMASK masks out are the same as the file permissions themselves. So, the left-most position masks out the owner permission, the middle position the group, and the right most masks out all others. If we have UMASK=007, the permissions for owner and group are not touched. However, for others, we have the value 7, which is obtained by setting all bits. Because this is a mask, all bits are unset. (The way I remember this is that the bits are inverted. Where it is set in the UMASK, it will be unset in the permissions, and vice versa.)
  • The problem many people have is that the umask command does not force permissions, but rather limits them
  • Therefore, setting the UMASK=007 does not force creation of executable programs, unless the program creating the file does itself).
  • ...6 more annotations...
  • - - regular file c - character device b - block device d - directory p - named pipe l - symbolic link
  • Lets look at a more complicated example. Assume we have UMASK=047. If our program creates a file with permissions 777, then our UMASK does nothing to the first digit, but masks out the 4 from the second digit, giving us 3. Then, because the last digit of the UMASK is 7, this masks out everything, so the permissions here are 0. As a result, the permissions for the file are 730. However, if the program creates the file with permissions 666, the resulting permissions are 620. The easy way to figure out the effects of the UMASK are to subtract the UMASK from the default permissions that the program sets. (Note that all negative values become 0.)
  • You can change it anytime using the umask command. The syntax is simply umask <new_umask>
  • Here the <new_umask> can either be the numeric value (e.g., 007) or symbolic. For example, to set the umask to 047 using the symbolic notation, we have umask u=,g=r,o=rwx
  • Where "new_owner" is the name of the user account we want to sent the owner of the file to, and "filename" is the file we want to change. In addition, you can use chown to change not only the owner, but the group of the file as well. This has the general syntax: chown new_owner.new:group filename
  • Another useful trick is the ability to set the owner and group to the same ones as another file. This is done with the --reference= option, which sets to the name of the file you are referencing. If you want to change just the group, you can use the chgrp command, which has the same basic syntax as chown. Not that both chgrp and chmod can also take the --reference= option. Further, all three of these commands take the -R option, which recursively changes the permissions, owner or group.

    An announcement by Google, about the launch of a product that took the approach of human rights by design in the technology industry. Launch of a new celebrity recognition application program interface (API) for use in the media and entertainment industry. This API will enable Google's customers to identify celebrities in their content at a frame-by-frame to scene-by-scene level using a database of celebrity images licensed by Google. While developing this API, Google also approached consultants who can help Google by identifying, preventing, and mitigating the potential human rights impacts. As per the best software development company in Noida, this approach of Google is best practice in developing such products because of the increasing involvement of individuals in the technology usage. All IoT solutions providers are also looking forward to Google developing such APIs as these efficient APIs will help the Website development company and Companies doing mobile app development in IT Industry to provide much more evolved IoT solutions to their clients. Although as we know, it can never be possible to eliminate all human rights risks, hence with a better approach and consultation with Human Rights Consultants an API with a significantly lower human rights risk profile can be developed. Companies like India railways portfolio and fadsan portfolio will be benefitted by this API, once Google develops it in a manner that does not, hampers potential human rights impacts, such as privacy, freedom of expression, security, child rights, non-discrimination, and access to culture. As per graphics design, Applying "Service Specific Terms" to limit the use of the celebrity recognition API to professionally filmed media content.
