How to use cat with pipes?

You can use the cat command with pipes (|) to pass the output of cat to another command for further processing. Here are a few examples:

Piping to grep: You can use cat to display the contents of a file and then pipe it to grep to search for specific text.
```
cat filename.txt | grep "search_term"
```
Piping to less: If the file is large, you can pipe the output to less for easier navigation.
```
cat filename.txt | less
```
Piping to wc: You can count the number of lines, words, or characters in a file by piping the output to wc.
```
cat filename.txt | wc -l  # Counts the number of lines
```
Piping to sort: You can sort the contents of a file by piping it to sort.
```
cat filename.txt | sort
```

Using pipes with cat allows you to create powerful command combinations for processing text data efficiently.
