# sum
|
||
|
|
|
||
|
|
This command allows you to calculate the sum of values in a column.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
To get the sum of the file sizes in a directory, simply pipe the size column from the ls command to the sum command.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
> ls | get size | sum
|
||
|
|
━━━━━━━━━
|
||
|
|
value
|
||
|
|
━━━━━━━━━
|
||
|
|
51.0 MB
|
||
|
|
━━━━━━━━━
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that sum only works for integer and byte values at the moment, and if the shell doesn't recognize the values in a column as one of those types, it will return an error.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
> open example.csv
