The SSH `cat` (concatenate) command displays file contents in your terminal and can also create small files. In particular, it's useful for quickly viewing configuration files, logs, or text files without opening an editor. Furthermore, you can combine multiple files, add line numbers, or create new files by redirecting output.

## Viewing file contents

To display the contents of a file:

```
cat myfile.txt
```

For example, to check your WordPress configuration:

```
cat wp-config.php
```

For large files, `cat` scrolls everything at once. Consider using `head` or `tail` to view only the beginning or end, see our guide on [head and tail commands](https://jethost.com/kb/how-to-use-linux-head-and-tail-commands/).

## Viewing multiple files

SSH `cat` command concatenates files in order and displays them together:

```
cat file1.txt file2.txt
```

Useful when you need to compare or merge the output of several files.

## Creating a new file

To create a file by typing content directly:

```
cat > newfile.txt
```

Type your content, then press **Ctrl+D** to save and exit. This overwrites the file if it already exists. To append instead of overwrite, use `cat >> newfile.txt`.

## Useful options

**Show line numbers:**

```
cat -n myfile.txt
```

**Show line endings (useful for debugging):**

```
cat -e myfile.txt
```

Displays `$` at the end of each line so you can spot hidden characters or Windows-style line endings.

**Show tabs as ^I:**

```
cat -T myfile.txt
```

Makes tab characters visible, helpful when checking indentation or formatting.

When you need to edit files rather than just view them, use `nano` or `vi` instead of `cat >`. These editors give you more control and let you navigate, search, and correct mistakes before saving. Additionally, for copying file contents into another file or command, you can pipe `cat` output, for example, `cat file.txt | grep "search"`.
