Bash "IF STATMENT with Decimal condition check"

Question

how to use decimal condition check with IF STATEMENT. below program gives an error while checking the if condition.

#!/bin/sh
usep=$(uptime | awk '{ print $10 }')
usep1=$(echo $usep | awk '{ print $1}' | cut -d'%' -f1)`enter code here`
usep1=${usep1%/}
usep2=${usep1%,}    #   Remove ","
echo $usep2
    if [ $usep2 <= 0.1 ]; then
    echo $usep2
    fi

Use `-le` for comparing numbers not `<=` – Mark Setchell Jun 24 '14 at 18:33 — Mark Setchell, Jun 24 '14 at 18:33

For floating point arithmetic you can use awk:

awk -v s="$usep2" 'BEGIN{if (s < 0.1) print s}'
