That works ok for in-line code snippets, but it doesn’t really work for multiple lines of code. If you use 3 backticks (```) in the line before and again in the line after your block of code it works much better
eg
read DATE TIME VOLTAGE AMPS FREQUENCY POWER TOTKWH < /home/pi/DDSD285/meter_data.txt
#
#
/usr/bin/curl -s -m 3 --connect-timeout 2 "http://192.168.0.182/emoncms/input/post?node=TWHGOFFICE&json={POWER:$POWER,TOTKWH:$TOTKWH,VOLTAGE:$VOLTAGE,AMPS:$AMPS}&apikey=5880fexxxxxxxxxxxxxxxxxxxxxxx0493" > /dev/$
would be displayed as
read DATE TIME VOLTAGE AMPS FREQUENCY POWER TOTKWH < /home/pi/DDSD285/meter_data.txt`
#
#
/usr/bin/curl -s -m 3 --connect-timeout 2 "http://192.168.0.182/emoncms/input/post?node=TWHGOFFICE&json={POWER:$POWER,TOTKWH:$TOTKWH,VOLTAGE:$VOLTAGE,AMPS:$AMPS}&apikey=5880xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx0493" > /dev/$
Longer code snippets are also reduced with a vertical scroll bar added, here’s the 2 scripts that were linked for downloading (much easier to view within the thread)

# -s is the curl "silent" switch.
# -m sets the maximun amount of time (in seconds) curl is allowed for the entire send transaction.
# set the node number to the node that has the data you want to transmit.
#
# Variables
# GENW = GENerated power in Watts, from my pv system
# HTOT = House TOTal. total house load, in Watts.
# VOLT = self explanatory.
# CONS = present CONSumption in Watts.
# TEC = Total Energy Consumed in KWh.
# IMPA = IMPorted energy, Leg A, in KWh.
# IMPB = IMPorted energy, Leg B, in KWh.
# EXPA = EXPorted energy, Leg A, in KWh.
# EXPB = EXPorted energy, Leg B, in KWh.
# NETA = NET energy, Leg A.
# NETB = NET energy, Leg B.
# NETC = pv production in KWh.
It’s much easier to discuss code without needing to download it, Just plant the code between 2 sets of 3 back ticks eg
```
chunk of code
