# Status Bar

Status bar is a program that is executed every time the cursor is moved. It is used to display additional information
about the current file.

For example, to simulate the `ls -l` command, you can use the following status bar program:

```bash
export WALK_STATUS_BAR='[Mode(), Owner(), Size() | PadLeft(7), ModTime() | PadLeft(12)] | join(" ")'
```

## Syntax

The syntax of the status bar program is based on the [expr](https://expr-lang.org/docs/language-definition) language.
