How do I escape a backslash in LaTeX?

In LaTeX, the backslash \ is a special character used to initiate commands. Therefore, to display a literal backslash, you need to escape it. Here’s how:

To display a single backslash in your LaTeX document, you need to use the command \textbackslash. This command instructs LaTeX to treat the backslash as a normal character instead of a command prefix.

Example:

If you want to display a path like C:\folder\file.txt in LaTeX, you would write it as follows:

C:\textbackslash folder\textbackslash file.txt

This will produce the output:

C:\folder\file.txt

Important Note:

While \textbackslash is the standard way to display a backslash, it's important to consider the context. For paths and code snippets, you might also find verbatim environments or the texttt command to be more appropriate. These alternatives can be helpful if you have multiple backslashes or special characters to display.

Alternatives:

Using \verb|C:\folder\file.txt| will also display C:\folder\file.txt without needing to escape the backslashes.

Using the texttt command, like \texttt{C:\textbackslash folder\textbackslash file.txt} can also be used, providing a monospace font.

In summary, use \textbackslash to display a backslash as a character in LaTeX. However, depending on your needs, verbatim or texttt could be better alternatives especially when you need to display code or paths with many backslashes.
