Alternative to udev functionality on OSX
提问by S1syphus
I'm trying to create a custom file/check in check out script for external hardrives, however part of the script is from a Linux machine, which I have tested works fine, but uses udevinfo, OS X doesn't have udev, so is there anything that offers the same functionality?
我正在尝试为外部硬盘创建自定义文件/签入签出脚本，但是脚本的一部分来自 Linux 机器，我测试过它工作正常，但使用udevinfo，OS X 没有 udev，所以有什么可以提供相同功能的吗？
#!/bin/bash
declare -a EXTERNAL_DISKS
declare -a INTERNAL_DISKS
for disk in /dev/[sh]d[a-z]; do
eval `udevinfo -q env -n $disk`
[ "$ID_BUS" = "usb" ] && EXTERNAL_DISKS=( ${EXTERNAL_DISKS[@]} $disk )
[ "$ID_BUS" = "scsi" ] && INTERNAL_DISKS=( ${INTERNAL_DISKS[@]} $disk )
done
echo "Internal disks: ${INTERNAL_DISKS[@]}"
echo "External disks: ${EXTERNAL_DISKS[@]}"
Anybody know any alternatives? Or a way this could be accomplished on OSX using bash?
有人知道任何替代方案吗？或者可以使用 bash 在 OSX 上完成的方法？

disks[rPFS(shell('diskutil info -plist ' + disk))['Internal']].append(disk)
print "Internal disks: " + ' '.join(disks[True])
print "External disks: " + ' '.join(disks[False])

IOKit manages devices, DiskArbitration manages mass storage devices on top of that. Neither has much in the way of a scripting interface.
IOKit 管理设备，DiskArbitration 在此之上管理大容量存储设备。两者都没有太多的脚本界面。
