Bash：需要整数表达式

这最近停止工作。知道我是否需要更改代码中的任何内容吗？

TIME=`grep real < /tmp/EV_Check.time | cut -d ' ' -f2`
time=$TIME
test $time -ge $ct
result=$?
        if [ "$result" -eq "1" ]
        then
        crit=1
        msg="Report execution takes $time!"
        fi
test $time -ge $wt
result=$?
        if [ "$result" -eq "1" ]
        then
        warn=1
        msg="Report execution takes $time!"
        fi

if [ $crit -eq 1 -a $warn -eq 0 ]
then
       echo "Critical value must be greater than warning value !"
       help_usage
       exit 3
fi

我收到以下错误：-

./check_ev_report.sh: line 158: test: 0.45: integer expression expected
./check_ev_report.sh: line 166: test: 0.45: integer expression expected
OK - 0.45

bash 只能进行整数运算。

如果您想比较浮点值，则必须调用外部工具，例如bc

if [[ $(bc <<<"$time >= $ct") == "1" ]]; then
    do_something
fi
