Here is a simple example of piping two commands, `ls` and `grep`, to list all the text files in the current directory:
```bash
ls | grep .txt
ls | grep '\.txt$'
```
In this example, `ls` lists the files in the current directory and `grep .txt` filters out any files that don't end with `.txt`. The pipe command, `|`, takes the output from `ls` and uses it as the input to `grep .txt`. The output of the entire command is the list of text files in the current directory.
