awk can parse and calculate alone. you don't need parse it twice. And there is stillx daysyou may want to consider.

What's the value ofuptime? Maybe it's locale dependent.

The$is already protected from expansion inside the single quotes you used to provide theawkscript; the backslash is unnecessary and preventingawkfrom using it as a field expansion.

You are overquoting the $s in the awk scripts:
hrs=`uptime | awk '{print $5}' | sed 's/[:,]/ /g' | awk '{print $1}'`
mins=`uptime | awk '{print $5}' | sed 's/[:,]/ /g' | awk '{print $2}'`
You're also doing more work than is necessary. Get the uptime once:
uptime=$(uptime | awk '{print $5}')
Then split the value on a : using the shell itself.
IFS=: read hrs min <<< "$uptime"
