文件读取

1.逐行读取

            FIR_URL=""
            FIR_ICON=""
            while read rows; do
                if [[ $rows =~ 'Published succeed: ' ]]
                then
                     FIR_URL=${rows##*'Published succeed: '}
                     echo "日志日志日志日志日志日志日志"
                elif [[ $rows =~ 'Local qrcode file: ' ]]
                then
                     FIR_ICON=${rows##*'Local qrcode file: '}
                     echo "日志日志日志日志日志日志日志2"
                else
                    echo ''
                fi
                echo "Line contents are : $rows";
            done < "/Users/***/Desktop/Package/***/fir.log"

2.从尾部读取-tail

            FIR_LOG=$(tail -n 2 "$export_path/fir.log")
            echo "日志====${FIR_LOG}"
            echo ${FIR_LOG##*'/Users'}
