+Usage: $PROG <file_count> <items_per_file> [input_content]
+
+Split input content into multiple JSON files with specified item counts.
+Files will be saved in the current directory.
+
+Arguments:
+  file_count        Number of output files to create
+  items_per_file    Number of items each output file should contain
+  input_content     (Optional) Direct input with newline-separated items.
+                   If not provided, will read from clipboard.
+
+Example:
+  $PROG 3 5 "1111\n1111\n1111"  # Direct string input
+  $PROG 2 3                      # Read from clipboard
+  $PROG 2 3 "$(pbpaste)"         # Explicit clipboard input

+----------------------
+`pb2json`用于将剪贴板或直接输入的文本内容按指定数量分割为多个JSON格式文件，每个文件包含指定数量的数组元素。
+支持`Linux`、`Mac`、`Windows`。
+
+### 用法/示例
+pb2json <文件数量> <每文件条目数> [输入内容]
+参数说明
+参数	必选	说明
+文件数量	是	要生成的JSON文件数量
+每文件条目数	是	每个JSON文件包含的条目数
+输入内容	否	直接输入的文本内容（不提供则读取剪贴板）
+
+```bash
+示例1：直接输入文本
+pb2json 2 3 "1111\n2222\n3333\n4444\n5555"
+输出：
+Created: output_01.json (3 items)
+Created: output_02.json (2 items)
+Success: Split 5 items into 2 JSON files in /current/directory
+
+
+示例2：读取剪贴板内容
+
+# 先复制内容到剪贴板
+printf "apple\nbanana\ncherry\ndate" | pbcopy
+
+# 执行转换
+pb2json 1 4
+
+Created: output_01.json (4 items)
+Success: Split 4 items into 1 JSON files in /current/directory
