Answer / harendra

Data structures that contain information about files in Unix file systems that are created when a file system is created. Each file has an inode and is identified by an inode number (i-number) in the file system where it resides. inodes provide important information on files such as user and group ownership, access mode (read, write, execute permissions) and type.

There are a set number of inodes, which indicates the maximum number of files the system can hold.

A file's inode number can be found using the ls -i command, while the ls -lcommand will retrieve inode information.

Predict the output of the following program code main() { fork(); printf("Hello World!"); }
