## Command line
|
||
|
|
|
||
|
|
Enable console logging with the `--logLevel` command line flag.
|
||
|
|
|
||
|
|
Hugo has four logging levels:
|
||
|
|
|
||
|
|
error
|
||
|
|
: Display error messages only.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo --logLevel error
|
||
|
|
```
|
||
|
|
|
||
|
|
warn
|
||
|
|
: Display warning and error messages.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo --logLevel warn
|
||
|
|
```
|
||
|
|
|
||
|
|
info
|
||
|
|
: Display information, warning, and error messages.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo --logLevel info
|
||
|
|
```
|
||
|
|
|
||
|
|
debug
|
||
|
|
: Display debug, information, warning, and error messages.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo --logLevel debug
|
||
|
|
```
|
||
|
|
|
||
|
|
{{% note %}}
|
||
|
|
If you do not specify a logging level with the `--logLevel` flag, warnings and errors are always displayed.
|
||
|
|
{{% /note %}}
|
||
|
|
|
||
|
|
## Template functions
|
||
|
|
|
||
|
|
You can also use template functions to print warnings or errors to the console. These functions are typically used to report data validation errors, missing files, etc.
