Question

我是Bash脚本的新手。

以下是脚本中包含的命令：

arecacli64 disk info通常会：

  # Ch# ModelName                       Capacity  Usage

我的简单脚本是：

F=`dmidecode |grep  "Product Name:"|cut -d ":" -f2|head -1`

if [ $F == "X7DB8" ]
then
echo
echo
echo -e "$VERT" HOSTNAME : `hostname`"$NORMAL"
echo -e "$BLEU" TYPE :"$NORMAL" `dmidecode -s system-manufacturer`
echo -e "$BLEU" MODEL :"$NORMAL" `dmidecode -t system |grep "Product Name:"|cut -d ":" -f2`


echo "-------------------->"
echo

echo -e  `/usr/local/bb/ext/Raid/arecacli64 disk info`

fi

但是结果显示（raid ctrl的部分）没有显示命令arecalcli64 disk info

的任何标签

 HOSTNAME : xxxx@www.com
 TYPE : Supermicro
 MODEL : X7DB8
-------------------->

我尝试使用\t \或sed等。

Answer 1

而不是

echo -e  `/usr/local/bb/ext/Raid/arecacli64 disk info`

只需使用

/usr/local/bb/ext/Raid/arecacli64 disk info

Answer 2

如果引用命令替换，您将获得正确的输出。

echo  "`/usr/local/bb/ext/Raid/arecacli64 disk info`"

不需要-e标志，因为您没有指定任何\t个字符;该标签嵌入在arecacli64的输出中，并通过引用保留它的输出。

但正如kkeller指出的那样，首先不需要使用命令替换。
