> : Overwrite (delete existing content and write new content)

echo "Hello" > hello.txt

Result:

• If hello.txt doesn't exist, it will be created
• If it does exist, its content will be cleared and replaced with "Hello"

>> : Append (add new content at the end of the file)

echo "See you again" >> hello.txt

Result:

• Adds "See you again" as a new line at the end of hello.txt
• Keeps the existing content unchanged

Example:

ls -l > ls.txt

Explanation:

• This command runs ls -l, which shows a detailed list of files in the current folder
• Instead of printing the result in the terminal, it saves the output to a file named ls.txt
• If ls.txt already exists, its content will be overwritten
