Backup! Backup! Backup! Always back up your Drupal site's code and database before you actually start making any changes to your site. Do you have access to the control panel? Cool! Go ahead and create a zip file of your entire site, export your db, download it to your local machine and you are done. Read on to know how to backup your Drupal site.
As a web developer, we sometimes may want to export a specific table from a MySQL database. It can be particularly helpful when we are going to apply some changes to a table that is part of a large database and we are interested in backing up that specific table only, rather that whole huge database.
The command "setfacl" refers to Set File Access Control Lists and "getfacl" refers to Get File Access Control List. Each file and directory in a Linux filesystem is created with a specific set of file permissions for its access. Each user can have different set of file access permissions. The permissions can be set using the setfacl utility. In order to know the access permissions of a file or directory we use getfacl. The getfacl command displays the access permissions of files and directories with file name, owner, group and the ACL's(Access Control List). When we create a directory it is created with a default set of access permissions and by using getfacl we will be able to see the access rights.

wget -S --spider www.example.com
