本文主要是介绍Fuchsia操作系统workstation系统,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!

 

在fuchsia编译完成之后,使用fx run可在qemu上运行。以下大致看一下它的目录结构。首先是顶层目录,如下,fuchsia没有传统的linux系统的usr、home、proc之类的目录。

$ ls -l /
drwxr-xr-x    1 0        0                 0 Jul 21 23:33 bin
dr--------    1 0        0                 0 Jan 01  1970 blob
dr--------    7 0        0                 0 Jan 01  1970 boot
drw-r--r--    7 0        0              8192 Jun 11 06:27 data
drw-------    1 0        0                 0 Jan 01  1970 dev
dr--------    1 0        0                 0 Jan 01  1970 hub
dr--------    2 0        0                 0 Jan 01  1970 install
drwxr-xr-x    1 0        0                 0 Jul 21 23:33 pkgfs
dr--------    1 0        0                 0 Jan 01  1970 svc
drwxr-xr-x    1 0        0                 0 Jul 21 23:33 system
dr--------    3 0        0                 0 Jun 11 06:27 tmp
dr--------    2 0        0                 0 Jan 01  1970 volume

由以下export命令可知,其可执行目录由两个/bin和/boot/bin目录。

$ export
export PATH='/bin:/boot/bin'
export PWD='/'
export TERM='xterm'

 

如下为/bin目录内容(内容有省略):

$ ls -l /bin

-r--------    1 0        0                56 Jan 01  1970 dirname
-r--------    1 0        0                46 Jan 01  1970 du

 

fuchsia的boot目录如下:

fuchsia的设备文件与linux系统类似,存放在/dev目录下,但是组织方式不同。其顶层目录如下:

$ ls -l dev/
drw-------    1 0        0                 0 Jan 01  1970 class
drw-------    1 0        0                 0 Jan 01  1970 misc

crw-------    1 0        0           0,    0 Jan 01  1970 zero

目录/dev/class保存安装类别的设备节点文件:

$ ls -l dev/class/
drw-------    1 0        0                 0 Jan 01  1970 acpi

drw-------    1 0        0                 0 Jan 01  1970 sysmem

目录/dev/misc目录下的文件与linux系统的/proc/misc文件的内容相似,为特殊的字符型设备节点。

$ ls -l dev/misc/
crw-------    1 0        0           0,    0 Jan 01  1970 console

目录system的子目录如下:

$ ls -l system/
drwxr-xr-x    1 0        0                 0 Jul 21 23:33 bin
