我有以下代码，无法比较两个相等值的字符串

    InptheaderRow=$(head -1 $InptFileName)

    echo $(head -1 $InptFileName)

    echo $BaseHeaderRow

    if [[ "$BaseHeaderRow" = "$InptheaderRow" ]]; then
            echo "<img class=\"message\" src=\"../images/success.png\">&nbsp&nbsp Valid Header Recond Found in $InptFileName"  | tee -a ${LOGFILE}
            CheckDelimetersInHeader
    else
            echo "<img class=\"message\" src=\"../images/error.png\">&nbsp&nbspNo Valid Header Record Found in $InptFileName"  | tee -a ${LOGFILE}
            echo "Exiting.."  | tee -a ${LOGFILE}
            exit 1
    fi
    }

下面的输出

不确定这里出了什么问题
