bash, search for usb storage devices. output location
提问by user2225483
I am looking for a way to list any usb connected devices or removable storage media.
我正在寻找一种方法来列出任何 USB 连接的设备或可移动存储介质。
I will be using this list for a gtk boot media writer, so a user can easily write an iso to a usb.
我将使用此列表作为 gtk 启动媒体编写器，因此用户可以轻松地将 iso 写入 USB。
This creates a perfect list of ALL partitions:
这将创建所有分区的完美列表：
ls /dev | grep "[sh]d[a-z][1-9]"
How can I get a similar looking list that is only removable media?
我怎样才能得到一个类似的列表，它只是可移动媒体？

On my system (Ubuntu 12.04), I can get a list of USB devices and partitions with
在我的系统 (Ubuntu 12.04) 上，我可以获得 USB 设备和分区的列表
ls /dev/disk/by-path/*usb*
giving
给予
/dev/disk/by-path/pci-0000:00:02.1-usb-0:1.1:1.0-scsi-0:0:0:0
/dev/disk/by-path/pci-0000:00:02.1-usb-0:1.1:1.0-scsi-0:0:0:0-part1
or partitions alone
或单独分区
ls /dev/disk/by-path/*usb*part*
These are symbolic links, pointing to the real device files, /dev/sddand /dev/sdd1for example.
这些符号链接，指向真实的设备文件，/dev/sdd以及/dev/sdd1例如。
I have tested this with a USB stick and an external USB hard disk only. I cannot say, whether or how this works with eSATA or Firewire disks.
我仅使用 USB 记忆棒和外部 USB 硬盘对此进行了测试。我不能说这是否或如何与 eSATA 或 Firewire 磁盘配合使用。

Based on the answer of Olaf Dietsche, I end up with the following:
根据 Olaf Dietsche 的回答，我最终得出以下结论：
devs=`ls -al /dev/disk/by-path/*usb*part* 2>/dev/null | awk '{print()}'`; for dev in $devs; do dev=${dev##*\/}; echo -n "$dev ("; echo -n `mount | grep \`echo -E ${dev}\` | awk '{print()}'`; echo ")"; done
For me the above code is showing the usb devices and where they are mounted (between parentheses). It worked on Ubuntu 13.04 and 12.04.2, but I do not know if it will work on any other system.
对我来说，上面的代码显示了 USB 设备及其安装位置（在括号之间）。它适用于 Ubuntu 13.04 和 12.04.2，但我不知道它是否适用于任何其他系统。

To get the mounted path of usb storage use
获取usb存储使用的挂载路径
mount|grep /media|awk '{print $3}'
mount|grep /media|awk '{print $3}'
explanation to command
命令的解释
mount will print all the mounted drives and grep will display only drives mounted in /media, (considering /media is default mount point ) this output is piped to awk which will print the mounted path of usb drive
mount 将打印所有已安装的驱动器，grep 将仅显示安装在 /media 中的驱动器，（考虑 /media 是默认安装点）此输出通过管道传输到 awk，它将打印 USB 驱动器的安装路径

bootisoBASH utility just do that when called with -loption. Here is the output of a slightly modified bash snippet:
bootisoBASH 实用程序只是在使用-l选项调用时执行此操作。这是稍微修改的 bash 片段的输出：
/dev/sdd /dev/sde
Relevant snippet:
相关片段：
printUSBDevices() {
typeset -a usbDevices
typeset -a devices
getDeviceType() {
typeset deviceName=/sys/block/${1#/dev/}
typeset deviceType=$(udevadm info --query=property --path="$deviceName" | grep -Po 'ID_BUS=\K\w+')
echo "$deviceType"
}
mapfile -t devices < <(lsblk -o NAME,TYPE | grep --color=never -oP '^\K\w+(?=\s+disk$)')
for device in "${devices[@]}" ; do
if [ "$(getDeviceType "/dev/$device")" == "usb" ]; then
usbDevices+=("/dev/$device")
fi
done
echo "${usbDevices[@]}"
}
printUSBDevices

Maybe you can use the output of lsusbcommand :
也许您可以使用lsusb命令的输出：
