Linux uses a unified filesystem structure that complies with the filesystem hierarchy standard, which, while not always immediately intuitive, is designed to make it an easier task of locating specific files on the system manually, and also to allow software written for it to be able to predict where its needed files are kept.
Here are the factors to consider before choosing a file organisation method; 1. Frequency of update: A file that needs to be updated every now and then needs an organisation method that will allow easy retrieval of information and ease of updating, example of such a file is the transaction file. 2. File activity: Different files have different activities, example a sort file is used to sort data in sequential order and therefore sequential method would be appropriate for such a file. 3. File access method: Definately different files have different methods of being accessed, example a reference file is accessed using random method for easy retrieval of data. 4. Nature of the system: Files that are used in a particular system will depend on the nature of the system i.e the suitable organisation method for that particular system. 5. Masterfile medium: The masterfile is the main file for keeping permanent updates of records from transaction files and other sources, the medium by which it is updated will determine the organisation method to be used.
In Linux the chmod command is used to set file permissions.
The Linux VFS (Virtual File System) may be thought of as a sort of interface between the Linux kernel and the mounted file systems. There can be many different file system types mounted simultaneously and VFS allows the Linux kernel to see and address them all in a similar way. This provides Linux with a great deal of flexibility. [JMH]
The Linux Filesystem Hierarchy is used to help determine the file structure in the Linux Operating System. It defines the Directory structure and directory contents.
touch newfile will make a new empty file in linux os !
The unknown compression method used in this file is not specified or identified.
Alternate references to a file/directory.
Need to be more specific in your question.
It means that the file or directory is used for application settings.
NFS provides a method for accessing remote file systems over a network. This can be used for multiple purpose, including unified logins and diskless thin clients.
in terminal it is : #cp file_a file_b
