By default, `count` will return the number of rows in a table
|
|
|
|
```shell
|
|
> ls | count
|
|
20
|
|
```
|
|
|
|
The `-c` flag will produce a count of the columns in the table
|
|
|
|
```shell
|
|
> ls | count -c
|
|
4
|
|
```
|
|
|
|
```shell
|
|
> ls | where type == File | count
|
|
11
|
|
```
|
|
|
|
```shell
|
|
> ls | where type == Dir | count
|
|
9
|
|
```
|
|
|
|
```shell
|
|
> ls | where size > 2KB | count
|
|
4
|
|
```
