FILE SYSTEMS AND FILE MANAGEMENT Flashcards
Directory
a repository of files and other directories.
File
a collection of related data that appears to the user as a single block of information that is retained in storage.
An inode is
a data structure on a file system that stores all information about a file except its name and its actual data.
A hierarchical file system allows
a modular approach to data storage and search
The directory that a user is currently working in is the user’s
current directory.
All files on Linux systems are accessed as
part of a single tree-structured file system that is rooted at /
The absolute path to a file or directory consists of a
followed by a series of zero or more directory names, each followed by another / and then a final name.
The inode number is also known as the
file serial number and is unique within a particular file system
Files and directories in Linux have three types of permissions
: read, write and execute
Each file permission may be
on’ or ‘off’ for each of the three categories of users: the file or directory owner, other people in the same group as the owner, and all others.
The chmod command is used
to set file permissions.
