# rclone test histogram

Makes a histogram of file name characters.

## Synopsis

This command outputs JSON which shows the histogram of characters used
in filenames in the remote:path specified.

The data doesn't contain any identifying information but is useful for
the rclone developers when developing filename compression.

```
rclone test histogram [remote:path] [flags]
```

## Options

```
  -h, --help   help for histogram
```

See the [global flags page](/flags/) for global options not listed here.
