Reading from a text file, or unix console screen

Hi!

Can anyone tell me how can I insert an information from a text file to a
PostgreSQL database when the text file is continously being updated with a
new information.

Alternatively if I have a freebsd program which continously echoes to the
console screen some information, how can I insert that information to the
database and to correct columns, using some regular expressions method.

The information is like the following...
[PHP]
U:1.2.28, 9502935, 1(inactive),(absolute) bytes rx 0, tx 108, (absolute)
pkts rx 0, tx 1,
