FlyBack presents the user with a typical file-manager style view of their file system, but with additional controls allowing the user to go forward or backward in time. It shows to the user files that exist, do not exist or have changed since the last version, and allows them to preview them before deciding to restore or ignore them.
In Git, each blob is a version of a file, in which is the file's data. [61] A tree object is the equivalent of a directory. It contains a list of file names, [62] each with some type bits and a reference to a blob or tree object that is that file, symbolic link, or directory's contents. These objects are a snapshot of the source tree.
In version control systems, a repository is a data structure that stores metadata for a set of files or directory structure. [1] Depending on whether the version control system in use is distributed, like Git or Mercurial, or centralized, like Subversion, CVS, or Perforce, the whole set of information in the repository may be duplicated on every user's system or may be maintained on a single ...
Shared, all developers use the same file system; Client–server, users access a master repository server via a client; typically, a client machine holds only a working copy of a project tree; changes in one working copy are committed to the master repository before becoming available to other users
Users who can review the proposed changes can see a diff between the requested changes and approve them. In Git terminology, this action is called "committing" and one instance of it is a "commit." A history of all commits is kept and can be viewed at a later time. In addition, GitHub supports the following formats and features:
user: file owner g: group: members of the file's group o: others: users who are neither the file's owner nor members of the file's group a: all: all three of the above, same as ugo (empty) default: same as "all", except that bits in the umask will be unchanged
A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD systems use /home/ username or /usr/home/ username and Windows systems since Windows Vista use \Users\ username .
Files provided by commits are by default immutable, done by mounting the filesystem itself as read-only. OSTree allows for two mutable directories for storing user data: /etc and /var . It provides a mechanism to allow filesystem trees to add configuration files to /etc while also allowing system administrators to edit those files in a ...
