Question

For the following, identify command syntax and what each piece of the command line accomplishes:

### Explanation of Command

The command is: 

```
tr ' ' '\n' < textfile
```

#### Components:
1. **`tr`**: A command in Unix/Linux used to translate or delete characters.
2. **`' '`**: The space character; represents what we want to replace.
3. **`'\n'`**: The newline character; represents what we want to replace spaces with.
4. **`<`**: Input redirection operator; takes input from a file.
5. **`textfile`**: The file from which input is read.

#### Step-by-Step Breakdown:
1. **Identify Spaces**: The `tr` command identifies each space (`' '`) in the text.
2. **Replace with Newline**: Each space is replaced by a newline (`'\n'`).
3. **Sequence Order**: The characters of the file are read in the order they appear.
4. **Process Entire File**: This operation affects the whole file named `textfile`.
5. **Output**: The final output is a list of words from `textfile`, each on a new line.

#### Final Output Explanation
The net effect of executing this command is to transform a file where words are separated by spaces into a file where each word is on a separate line. If `textfile` contains the sentence "The quick brown fox", the output will appear as follows:
```
The
quick
brown
fox
```

This command is useful for processing text files to make each word stand alone on a separate line, facilitating tasks like line-by-line processing or analysis.
