//! Command implementation for removing directories from PATH.
//!
//! This module handles:
//! - Removing specified directories from PATH
//! - Creating backups before modification
//! - Updating shell configuration
//! - Maintaining PATH integrity

use crate::backup;

/// Executes the delete command to remove directories from PATH
///
/// # Arguments
///
/// * `directories` - A slice of strings containing directories to remove
///
/// # Example
///
/// ```
/// let dirs = vec![String::from("~/old/bin")];
/// commands::delete::execute(&dirs);
/// ```
