The proc filesystem is a pseudo-filesystem which provides an interface to kernel data structures. It is commonly mounted at /proc. Typically, it is mounted automatically by the system, but it can also be mounted manually using a command such as:
proc文件系统是一个伪文件系统, 它提供了一个到内核数据结构的接口。 它通常挂载在 /proc。通常情况下系统会自动挂载它。 但是用以下命令也能挂载
mount -t proc proc /proc
Most of the files in the proc filesystem are read-only, but some files are writable, allowing kernel variables to be changed.
实际尝试了一下:
user1@intel6248:~$ mkdir fakeproc
user1@intel6248:~$ sudo mount -t proc proc ./fakeproc
这个ls fakeproc目录就可以看到进程的信息了 :
user1@intel6248:~$ ls fakeproc/
