=== What does it mean the 4 values in ```/proc/sys/kernel/printk``` ? <lab01:ex03>
|
|
|
|
We can show what there is in:
|
|
|
|
```bash
|
|
|> cat /proc/sys/kernel/printk
|
|
7 4 1 7
|
|
```
|
|
The number specified the level of output in a console.
|
|
|
|
This file specifies the log level for: \
|
|
current (7), default (4), minimum (1) and boot-time default (7).
|
|
|
|
This number matches with this table (#link("https://www.kernel.org/doc/html/latest/core-api/printk-basics.html", [printk documentation])):
|
|
|
|
#table(
|
|
columns: (2fr, 1fr, 3fr),
|
|
|
|
[*Name*], [*String*], [*Alias function*],
|
|
|
|
