Certainly! Ex commands in Vim are incredibly useful for a range of text editing tasks. Here are some basic Ex commands that you should start with:
### 1. Opening and Saving Files
- **Open a file**: `:e filename` – Opens `filename` in the current buffer.
- **Write (save) the current file**: `:w` – Saves the changes you've made.
- **Save and quit**: `:wq` or `:x` – Saves changes and closes the editor.
- **Quit without saving**: `:q!` – Quits and discards any changes.
### 2. Line Manipulation
- **Go to a specific line**: `:#` – Where `#` is the line number you want to go to. For example, `:25` takes you to line 25.
- **Move lines**: `:#m#` – Moves a line to a new position. For example, `:2m5` moves line 2 below line 5.
- **Copy lines**: `:#t#` – Copies a line to a new position. For example, `:3t5` copies line 3 below line 5.
### 3. Searching and Replacing
- **Search for a text**: `:/pattern` – Finds the next occurrence of `pattern`.
- **Global search and replace**: `:%s/old/new/g` – Replaces all occurrences of `old` with `new` throughout the document. Remove the `g` if you only want to replace the first occurrence in each line.
### 4. Filtering and Executing External Commands
- **Filter lines through an external command**: `:#,#!command` – For example, `:1,10!sort` sorts lines 1 to 10.
- **Read the output of an external command into the buffer**: `:r !command` – For example, `:r !date` inserts the current date into the document.
### 5. Managing Multiple Files
- **Next file**: `:n` – Moves to the next file in the list of files opened with Vim.
- **Previous file**: `:prev` or `:p` – Moves to the previous file.
### 6. Setting Options
- **Set options**: `:set option` – Sets different configurations. For example, `:set number` turns on line numbering, `:set nonumber` turns it off.
### 7. Undo and Redo
- **Undo the last change**: `:undo` or just `u` in normal mode.
- **Redo the last undone change**: `:redo` or `Ctrl-r` in normal mode.
