if and then statements
I came across a bash script that outputs the forecast for the day and the max temperature but at the end of the day the max temperature disappears ($6) and I am left with "°C" after the forecast.

Here is the script:

Code:
#! /bin/bash

curl -s --connect-timeout 30 "ftp://ftp2.bom.gov.au/anon/gen/fwo/IDA00003.html" | grep "Melbourne" | sed -e 's,&nbsp;,,g' -e 's/<\/TD>/\]/g' -e 's/<[^>]*>//g' | awk -F ']' '{print "Today: " $4 " " $6"°C"}'
exit 0

I tried writing 'if' and 'then' statements such as

Code:
if [ "$6" == "" ]; then
'{print "Today: " $4}'

but I ended up with awk errors and such.

Any idea how to implement it in?

amdtemp

AMDTEMP(4)						   BSD Kernel Interfaces Manual 						AMDTEMP(4)

NAME

     amdtemp -- device driver for AMD K8, K10 and K11 on-die digital thermal sensor

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device amdtemp

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   amdtemp_load="YES"

DESCRIPTION

     The amdtemp driver provides support for the on-die digital thermal sensor present in AMD K8, K10 and K11 processors.

     For the K8 family, the amdtemp driver reports each cores' temperature through a sysctl node in the corresponding CPU devices's sysctl tree,
     named dev.amdtemp.%d.sensor{0,1}.core{0,1}.  The driver also creates dev.cpu.%d.temperature displaying the maximum temperature of the two
     sensors located in each CPU core.

     For the K10 and K11 families, the driver creates dev.cpu.%d.temperature with the temperature of each core.

BUGS

     AMD K9 is not supported because temperature reporting has been replaced by Maltese.

SEE ALSO

     sysctl(8)

HISTORY

     The amdtemp driver first appeared in FreeBSD 7.1.
