Linux training course description
A Linux foundation appropriate for all flavours of Linux,
focussed on getting network engineers up and running
with Linux. The command line is used throughout. The
course progresses from the basics of Linux commands
onto useful tools such as grep, then shell features such
as piping and then onto shell scripting. Administration
aspects covered are the tasks network engineers are
most likely to encounter such as software installation.
Hands on exercises concentrate on network related
tasks such as installing net-snmp and using shell
scripts to provide network automation.
