How do I find and replace all occurrences (in all files) in Visual Studio Code?

When using Visual Studio Code (VS Code), searching and replacing references across all files in a project is a common and important task. This can be done through the following steps:

1. Open the Search and Replace Panel

First, ensure you have opened the project or folder you want to modify.

• Use the shortcut Ctrl + Shift + F (on Windows/Linux) or Cmd + Shift + F (on Mac) to open the global search panel.

2. Enter the Search Term

In the opened search panel, input the content you want to search for. For example, if you need to replace all var keywords with let, enter var here.

3. Enable the Replace Function

Click the small arrow below the search bar to expand additional options, then click the "Replace" field to input your replacement content.

4. Enter the Replacement Content

In the replace field, input the new content you want to replace with. For example, in this case, you would enter let.

5. View and Replace

VS Code will display all matches. You can review each match individually, replace a specific occurrence, or select "Replace All".

• Click the replace button next to each search result (typically a right arrow icon) to replace one by one. If you confirm replacing all matches, click the "Replace All" button (typically a double arrow icon).

6. Use Regular Expressions and Case Sensitivity

For more precise searching, enable regular expressions or case-sensitive search. This is done by clicking the buttons adjacent to the search box.

Example

Suppose you are working on a JavaScript project and want to replace all var keywords with let. Open the global search, enter var, then enter let in the replace field. Review the search results to ensure replacements won't affect variable names like variableName. Finally, click "Replace All" to complete the operation.

Conclusion

Using VS Code's global search and replace feature is highly convenient, especially for quickly modifying multiple files across an entire project. It also supports advanced search patterns, such as regular expressions, making the process more precise and efficient.
