Command Function
This command is used to write data to the specified proc file system. The proc file system supports data of strings. The method for writing data needs to be implemented.
Syntax
writeproc <data> >> /proc/<filename>
Parameters
Table 1 Parameter description
Parameter | Description |
---|---|
data | Specifies the string to write, which ends with a space. If you need to write a space, use "" to enclose the space. |
filename | Specifies the proc file to which data is to write. |
Usage Guidelines
The proc file system implements its own write() function. Calling the writeproc command will pass input parameters to the write() function.
NOTE
The procfs file system does not support multi-thread access.
Note
Currently, the shell does not support this command.
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() function. The INFO log is generated by the test() function.
