User can also execute a program inside the mounted directory directly without implicit transfer.
The mount command will "mirror" the directory /home/user in your PC Linux (with IP = xxx.xxx.xxx.xxx)
to /mnt/ext1 in the eH880
Note that "1024" in the above example is necessary to ensure reliability when transferring big files.
Note also that the NFS service in your PC Linux have to be configured correctly to open permission of
the directory that is going to be mounted. See "man nfs" and "man exports" in PC Linux for detail.
Appendix A.3. Showing the Status of Processes
To show the status of processes, input “ps” (process status) command. The information is arranged
by Process ID (PID), User ID (Uid), Virtual Memory Size in bytes (VmSize), Process State (Stat) and
command line (Command).
According to the man page of “ps” command, the process state has the following meanings:
Process State Description
D uninterruptible sleep (usually IO)
R runnable (on run queue)
S Sleeping
T traced or stopped
Z a defunct ("zombie") process
W Has no resident pages
< High-priority process
N Low-priority task
L Has pages locked into memory (for real-time and
custom IO)
