Hands-on Sessions

File and directory navigation

Get started with the Unix file system. Explore the file system and use the key file and directory navigation commands.

Looking at files

Use Unix utilities to explore and manipulate the contents of files. Change access privileges.

Re-direction and output

Work with re-direction and piping techniques to transfer data between the standard Unix input and output devices.

Unix processes

Explore the exec and fork functions of a Unix process.

Text editor

This hands-on session will take you through the tips and tricks of vi.

Shell programming

Practice setting up your own shell and user environment. Write shell programs/scripts to undertake tasks.

Scheduling

Utilise the Unix cron and at utilities to schedule tasks.

Backup/restore

Undertake system backup and restore functions. Improve the backup and restore with compression techniques.
