Introduction : History, salient features, Unix system architecture, Unix command format, Unix internal and external commands, Directory commands, File related commands, Disk related commands, general utilities.
Unix File System : Boot inode, super and data block, in-core structure, Directories, conversion of pathname to inode, inode to a new file, Disk block allocation.
Process Management : Process state and data structures of a Process, User vs. kernel node, context of a Process, background processes, Process scheduling commands, Process terminating and examining commands.
Secondary Storage Management : Formatting, making file system, checking disk space, mountable file system, disk partitioning, file compression.
Special Tools and Utilities : Filters, Stream editor SED and AWK, Unix system calls and library functions, Processes, signals and Interrupts, storage and compression facilities.
Shell Programming : Vi editor, shell types, shell command line processing, shell script features, executing a shell script, system and user-defined variables, expr command, shell screen interface, read and echo statement, command substitution, escape sequence characters, shell script arguments, positional parameters, test command, file test, string test, numeric test. Conditional Control Structures – if statement, case statement Looping Control Structure – while, until, for, statements. Jumping Control Structures – break, continue, exit.
Unix System Communication : Introduction, write, read, wall commands, sending and handling mails.
System Administration : Roles of a System Administrator, File System Maintenance, System Startup and Shutdown, User Management, Backup and Restore, Daemons, Domain Name System DNS, Distributed File System.
