How Do I Perform a Basic Search in Vim?

To perform a basic search in Vim, use the /pattern command to search forward through your document. For example, /zeppelin will search for the word “zeppelin” from your current cursor position to the end of the file. To search backward, use ?pattern. After typing your search pattern, press Enter. You can navigate through the search results by pressing n to find the next occurrence and N to find the previous one.

How Can I Search for a Whole Word in Vim?

If you want to search for a whole word rather than a substring, use word boundaries in your search pattern. For example, /\<zep\> will match “zep” as a complete word, ignoring instances where “zep” is part of another word like “ledzeppelin”. This ensures that your search results are more precise and relevant.

How Can I Search Vim for the Current Word Under the Cursor?

Vim provides a quick way to search for the word under your cursor. Simply place the cursor on the word you want to search for and press * to search forward or # to search backward. This feature is incredibly handy for quickly navigating through instances of a particular variable or function name in your code.

How Can I Search and Replace Text in Vim?

To replace text, use the :s command. For instance, :s/old/new/g replaces ‘old’ with ‘new’ in the current line, while :%s/old/new/g performs the replacement throughout the entire file. If you need to replace text within a specific visual selection, use :s/\%Vold/new/g. This command confines the replacement to the selected area, making it useful for targeted edits.

How Do I Disable Case-Sensitive Search in Vim?

By default, Vim searches are case-sensitive. To make your searches case-insensitive, use the :set ignorecase command. If you want Vim to automatically switch to case-sensitive mode when you include uppercase letters in your search, also set :set smartcase. This smart combination provides flexibility based on your search needs.

How Do I Highlight Search Results in Vim Editor?

To highlight all occurrences of your search pattern, enable highlighting with :set hlsearch. This visual aid can help you quickly locate all matches in your document. When you’re done and want to clear the highlights, simply use :nohlsearch or :noh.

What Is Incremental Search in Vim and How Do I Use It?

Incremental search in Vim shows matches as you type your search pattern. This real-time feedback helps refine your search and quickly locate what you’re looking for. To enable incremental search, use :set incsearch.

How to View Search History in Vim Editor?

Vim keeps a history of your search patterns, which you can access by typing q/ for forward searches and q? for backward searches. This feature is particularly useful if you need to repeat previous searches or check your search history for complex patterns.

How Do I List All Matches of a Search in Vim?

To list all matches of a search pattern, use the :vimgrep /pattern/ % command followed by :copen. This command gathers all matches in the current file and opens them in the quickfix window, making it easy to navigate through them.

How Can I Navigate Through Search Results in Vim?

Besides using n and N to move through search results, you can also jump a specific number of matches by typing [number]n. For instance, 3n will move you to the third next occurrence of your search pattern.
