This expands the PATH setting. It adds /usr/sbin, /sbin and the bin dir in a home directory ($HOME/bin)

Use echo $PATH to see the full content of PATH.

Without a proper PATH (some of) the executables cannot be found.

EDIT: Also have a look here: Linux path environment variable

When directories are in your path, you do not need to enter the path to an application to run it. For example, if /usr/bin is in your path, you can enter

Code:
thunderbird
instead of

Code:
/usr/bin/thunderbird
to start the Thunderbird email client.
