[DANIEL MAGNUSZEWSKI]

Dan,

Pity has been taken:

<CODE>

#!/usr/bin/perl

# curl the data into a file (assuming the data you provided is the
format of
# the output of curl)

system("/usr/bin/curl http://url | grep \"Signal Strength\"
>/full/path/to/dishdatafile");

open FILE, "/full/path/to/dishdatafile" or die "Can't open
dishdatafile\n";
while (<FILE>)
{
        if (/Signal Strength[\.]+[\s]([\d]+)/)
        {
                print "$1\n$1\nuptime\ndevice\n";
        }
}

</CODE>

This *should* give you the following output:

80
80
uptime
device

I hope this helps.

I have a system with a high speed satellite connection.  The ISP
provides a handy local webpage with spits out various stats on the
system.  A curl of the page results in a plain html page with following
data that I want to use via MRTG:

Signal Strength.............. 80      Stream Msg-Ackd/Nakd........
824997/34
Flags............... 0x00000020       NonStream Msg-Ackd/Nakd.....
4123/119
UpTime (d:h:m:s).. 001:14:53:52       Aloha Starts................
4123
The Sequencer Timeout........ 0       Ranging Starts.............. 0
Transport Alarm Bit.......... None    Frames Received.............
12356891
Addresses Open............... 7       Frame Errors: CRC/Bad Key... 0/0
Carrier Info........ 091:W:1350       Miscellaneous Problems...... 1
Rate Code.................... 2       No Receive Outroute Lock.... 10
Inroute Group................ 5       No FLL Lock................. 237
Inroute...................... 13      No Network Timing Sync...... 56

For example I would like to plot 'Signal Strength' so I need to awk /
cut / grep / sed etc this file and spit out the required data
for MRTG in this case it would be: 80 80

The first part is easy:

curl http://myurl | grep "Signal Strength" which will get the line
containing my required data.  From here I am lost.

Can someone please take pity on me and give me an example of a script
that can do this.

Thanks,

Dan
