Notepad++正则表达式替换：保留指定字符合并特定方括号内容

Got it, let's figure out how to solve this targeted regex replacement in Notepad++. The key here is we only want to merge the second bracket into the first only when the line starts with * BATCH *—leaving all other ] [ pairs untouched. Here's exactly what to do:

Step 1: Open the Replace Dialog #

Hit Ctrl+H in Notepad++ to bring up the Find/Replace window—this is where we'll set up our regex.

Step 2: Configure Regex Settings #

Before entering patterns, make sure these settings are correct:

• Switch to the Regular expression search mode (select the radio button).
• Uncheck . matches newline (we don't want to match across line breaks here).
• If your * BATCH * is always uppercase, keep Match case checked to avoid accidental matches on lowercase variants.

Step 3: Enter the Regex Patterns #

Find what: #

(\* BATCH \* \[[^\]]+) \[([^\]]+)\]

Let me break this down so you know exactly what it's targeting:

• (\* BATCH \* \[[^\]]+): This first capture group grabs everything from * BATCH * [ up to (but not including) the closing ] of the first bracket. The [^\]]+ part ensures we only capture text inside that first bracket until we hit its closing ].
• \[([^\]]+)\]: This matches the space, opening [, captures the text inside the second bracket (as our second group), then the closing ].

Replace with: #

\1 \2]

Here's how this fixes the string:

• \1: Inserts the content from our first capture group (the start of the line up to the end of the first bracket's inner text, no closing ]).
• \2: Adds a space followed by the text we pulled from the second bracket.
• ]: Re-adds the closing bracket to complete the merged first bracket.

Step 4: Test and Apply Changes #

• First, click Find Next to double-check it's only matching the ] [ pairs you want to modify (the ones right after the first bracket in * BATCH * lines).
• Once you're confident it's targeting correctly, click Replace All to apply the changes across your entire document.

Example Results #

Let's verify with your sample inputs:

• Original: * BATCH * [Qh 4c 2c] [9h] [9c]
  After replacement: * BATCH * [Qh 4c 2c 9h] [9c] ✅
• Original: * BATCH * [Js 8c 3s] [8h] [Th]
  After replacement: * BATCH * [Js 8c 3s 8h] [Th] ✅

This regex won't touch any ] [ pairs outside of the * BATCH * context, so all your other content will stay exactly as it is.
