Usage

The proc file implements its own write command. Calling the writeproc command will pass the input parameter to the write command.

NOTE: The procfs file system does not support multi-thread access.

Example

Run writeproc test >> /proc/uptime.

Output

OHOS # writeproc test >> /proc/uptime

[INFO]write buf is: test

test >> /proc/uptime

NOTE: The uptime proc file temporarily implements the write command. The INFO log is generated by the implemented test command.
