Sto*_*aft 3 sysfs tree sensors
如果我理解正确的话,在 Linux 中,一切都是一条路径,一直到每个硬件。我试图获取有关传感器结构的信息,所以我想我只会使用树来映射 hwmon 目录中的所有内容。但是,树在此目录中的行为与我习惯的不同。
当我在普通目录上运行 tree 时,我在不使用 -R 或 -L 标志的情况下获得了子目录结构:
$ tree /home
/home
??? boss
??? clones
??? Desktop
??? Documents
? ??? modules.txt
? ??? old_docs
? ? ??? assorted
? ??? prepscript.txt
??? Downloads
??? Music
??? Pictures
??? Public
??? Templates
??? Videos
12 directories, 2 files

但我尝试对 HWmon 做同样的事情,它只会深入一层,即使我确实使用了 -R 标志并且即使有更深的东西:
$ tree /sys/class/hwmon/
/sys/class/hwmon/
??? hwmon0 -> ../../devices/pci0000:40/0000:40:01.3/0000:43:00.0/hwmon/hwmon0
??? hwmon1 -> ../../devices/pci0000:00/0000:00:01.3/0000:09:00.0/hwmon/hwmon1
??? hwmon2 -> ../../devices/pci0000:40/0000:40:03.1/0000:44:00.0/hwmon/hwmon2
??? hwmon3 -> ../../devices/pci0000:00/0000:00:18.3/hwmon/hwmon3
??? hwmon4 -> ../../devices/pci0000:00/0000:00:19.3/hwmon/hwmon4
??? hwmon5 -> ../../devices/virtual/thermal/thermal_zone0/hwmon5
??? hwmon6 -> ../../devices/platform/nct6775.656/hwmon/hwmon6

是什么导致了这种行为差异,我能否获得所有设备的简单树?
tree这样做是因为默认情况下它不会取消引用符号链接。该-l选项将改变:
tree -l /sys/class/hwmon/

但是你会很高兴理解所有的输出。
