How do I use the 'Find and Replace' feature in VS Code?
Jun 19, 2025 am 12:06 AM
The best way to make batch modifications in VS Code is to use the Find and Replace feature. 1. Use "Find and Replace" in a single file: Press Ctrl H to open the panel, enter the search and replace content, and click "Replace" or "Replace All". 2. Search across multiple files: Press Ctrl Shift F to open the search tab, expand the Replacement section, and select the replacement operation for a single file or entire project. 3. Use advanced options: such as case sensitivity, full word matching and regular expressions for more precise control, such as matching numbers with \d or using capture groups for complex replacements. This feature significantly improves code maintenance efficiency through fast and precise editing.
When you're working with code in VS Code and need to make relative changes across a file or multiple files, the "Find and Replace" feature is your best friend. It's fast, efficient, and saves you from doing tedious manual edits.
Basic Find and Replace in a Single File
To start, open the file you want to edit. Press Ctrl H (or Cmd Option F on Mac) to bring up the Find and Replace panel. In the first input box, type what you want to find, and in the second, what you want to replace it with.
Once both fields are filled, you can:
- Click “Replace” to change one match at a time.
- Click “Replace All” to update every instance in the file.
This works great for simple text changes, like renaming a variable or updating a function name that appears multiple times.
Use Search Across Multiple Files
If you want to replace something across your entire project or folder, use the global search feature. Press Ctrl Shift F to open the Search tab. Type what you're looking for in the top input field.
Then click the arrow next to the search bar to expand the Replace section. Enter your replacement text, and now you have options:
- Click the Replace icon next to an individual file result to apply changes there.
- Click “Replace All” above the results to update all matches across the project.
Be careful here — replacing globally can affect more files than you expect. It's a good idea to review the matches before hitting “Replace All.”
Advanced Options: Case Sensitivity and Regular Expressions
VS Code gives you extra control by letting you toggle additional settings:
- Match Case : Makes the search case-sensitive. So “Test” won't match “test” or “TEST.”
- Whole Word : Only finds full-word matches. Useful if you want to avoid partial replacements.
- Use Regular Expressions : This unlocks powerful pattern-based searching.
For example, if you want to replace all numbers in a certain format, you could use \d to match digits. Or if you want to capture part of a pattern and reuse it in the replacement, you can use $1 , $2 , etc., depending on your capture groups.
These tools are especially helpful when dealing with messy or inconsistent data in logs, configs, or large refactorings.
That's basically how it works. Whether you're tweaking one file or overhauling a whole project, the Find and Replace feature in VS Code makes it manageable without going line by line.

How do I open the integrated terminal in VS Code?
Jun 12, 2025 am 11:29 AM
The most common method to open a VSCode integrated terminal is to use keyboard shortcuts. By default, press Ctrl (backtick key) to open or focus the terminal panel; Mac users usually use Cmd. If the shortcut keys do not work, which may be a keyboard layout or custom settings issue, you can check or change it in Keyboard Shortcuts under the File menu. In addition, you can switch the terminal panel by opening it in the top menu "Terminal>New Terminal" or clicking the terminal icon in the activity bar on the left. If the icon is not displayed, right-click the activity bar and make sure "Terminal" is checked. You can also right-click in the editor tab and select "Open in Integration Terminal" to run the command in the directory where the current file is located or the project root directory.
