Streams and Pipes

Redirection

The < and > operators are used to redirect input and output in the terminal.

• < is used to redirect input from a file to a command.
• > is used to redirect output from a command to a file.

# Redirecting input from a file
cat < input.txt
# Redirecting output to a file
echo "Hello, World!" > output.txt

# Redirecting both input and output
cat < input.txt > output.txt

Pipes

Pipes are used to connect the output of one command to the input of another command. The | operator is used to create a pipe.

# Using pipes to connect commands
cat input.txt | grep "pattern" | sort

The above command reads the contents of input.txt, filters lines containing “pattern” using grep, and then sorts the filtered lines using sort.
