我认为我有一个很好的方法来确定哪些驱动器是内部驱动器,哪些驱动器是外部驱动器(USB)。直到我遇到这个:
的/ var /日志/消息*
Sep 24 03:40:02 myHostName kernel: sd 0:0:0:0: [sda] 3907029164 512-byte logical blocks: (2.00 TB/1.81 TiB)

Jul 26 15:19:39 myHostName kernel: sd 0:0:0:0: [sda] 3907029164 512-byte logical blocks: (2.00 TB/1.81 TiB)

Jul 26 15:23:28 myHostName kernel: sd 0:0:0:0: [sda] 976773168 512-byte logical blocks: (500 GB/465 GiB)
此系统上的SDA和SDB驱动器从内部交换到外部!有谁知道我如何识别哪些设备是内置的,哪些是外置的?我需要查看HISTORY,所以我真的需要能够回顾以前安装的设备。我的旧方法是查看“sdb-sdX”忽略sda的所有内容。这在上面的机器上是有缺陷的。我甚至都不知道它是怎么做到的。一直以为SDA是第一个内部设备。

我用它来识别驱动器是否可弹出(USB): -
diskutil info /dev/disk[n|s{n}] | grep Ejectable
“磁盘工具”为您提供所有磁盘的序列号。

在我的RHEL6系统上,我能够进行以下查询以获得我正在寻找的输出:
cat /var/log/messages* | egrep -i 'usb [0-9]-|mounted|logical blocks' > ${USBDATA}
cat ${USBDATA} | grep "New USB device found" > ${NewUSBDev}
while read line; do
MONTH="`echo ${line} | awk '{print $1}'`" ; # -- Jul
DAY="`echo ${line} | awk '{print $2}'`" # -- day_
HOUR="`echo ${line} | awk '{print $3}' | cut -d':' -f1`:" # -- hour:
MIN="`echo ${line} | awk '{print $3}' | cut -d':' -f2`:" # -- hour:
# -- echo "M:[$MONTH] D:[$DAY] H:[${HOUR}${MIN}]"
cat ${USBDATA} | grep ${MONTH} | grep "${DAY} ${HOUR}${MIN}" > ${CHUNK}
awk '/New USB device found/{p++}p==1' ${CHUNK} > ${TMPFILE}
cp ${TMPFILE} ${CHUNK}
if [ "$(cat $CHUNK| egrep 'MiB|GiB|TiB')" ] && ! [ "$(cat $CHUNK | grep 'Mounted root filesystem')" ] ;then
# -- cat ${CHUNK}
STR="$(less ${CHUNK}|grep 'idProduct' | head -1 | awk '{print $1" "$2" "$3" "$12" "$13}')"
STR="$STR $(less ${CHUNK}|grep 'Product:' | awk '{print ", "$9" "$10" "$11}')"
STR="$STR $(less ${CHUNK}|grep 'Manufacturer:' | awk '{print ", "$9" "$10" "$11}')"
STR="$STR $(less ${CHUNK}|grep 'SerialNumber:' | awk '{print ", "$9}')"
STR="$STR $(less ${CHUNK}|grep 'logical blocks:' | head -1 | awk '{print ", "$13" "$14" "$15" "}')"
echo "${STR}"
echo "${STR}" >> ${DEVICES}
fi
[ -f ${CHUNK} ] && rm ${CHUNK}
done < ${NewUSBDev}
echo "----------------------------------------------"
cat ${DEVICES} | sort -M -k 2 > ${SORTEDDEV}
cat ${SORTEDDEV}
基本上,它有点难看,但它会搜索所有“找到的新USB设备”,并列出包含该列表的行。然后拉出与该时间戳匹配的所有内容。然后在“找到新USB设备”之前拔出所有内容,并在“找到新USB设备”后第二次匹配后拔出所有内容。
示例$ {CHUNK}的数据如下所示:
Sep 30 09:55:10 oc7446274465 kernel: usb 2-1: New USB device found, idVendor=1058, idProduct=071a
Sep 30 09:55:10 oc7446274465 kernel: usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Sep 30 09:55:10 oc7446274465 kernel: usb 2-1: Product: My Passport 071A
Sep 30 09:55:10 oc7446274465 kernel: usb 2-1: Manufacturer: Western Digital
Sep 30 09:55:10 oc7446274465 kernel: usb 2-1: SerialNumber: 575846314136304130353235
Sep 30 09:55:10 oc7446274465 kernel: usb 2-1: configuration #1 chosen from 1 choice
Sep 30 09:55:22 oc7446274465 kernel: sd 5:0:0:0: [sdb] 1465092096 512-byte logical blocks: (750 GB/698 GiB)
将此数据放入临时文件中,然后查找重要位。这可以肯定地改进,但它现在可以工作(上面的代码中不包括grepping部分):
示例输出:
Sep 10 16:19:14 idVendor=8564, idProduct=1000 , Mass Storage Device , JetFlash , 2978449637 , (31.6 GB/29.4 GiB)

因此,我得到时间,ID信息,产品名称,序列等。我应该包括检查数据是否缺失。但你明白了。感谢投入的人。
