当脚本在一年的开始两天运行时，我使用下面的脚本将两天后移，并检查每个月的第一天和第二天，然后将后移两天。

if [$month="01"] && [$day="01"]; then
        date="$last_month/$yes_day/$last_year"
        fulldate="$last_month/$yes_day/$last_year"
else
        if [$month="01"] && [$day="02"]; then
                date="$last_month/$yes_day/$last_year"
                fulldate="$last_month/$yes_day/$last_year"
        else
                if [ $day = "01" ]; then
                        date="$last_month/$yes_day/$year"
                        fulldate="$year$last_month$yes_day"
                else
                        if [ $day = "02" ]; then
                                date="$last_month/$yes_day/$year"
                                fulldate="$year$last_month$yes_day"
                        else
                                date="$month/$yes_day/$year"
                                fulldate="$year$month$yes_day"
                        fi
                fi
        fi
fi

但我的坏消息是收到以下错误消息

Etime_script.sh: line 19: [06=01]: command not found
Etime_script.sh: line 24: [06=01]: command not found
