Can you explain '>>'?

The >> symbol has several significances depending on the context in which it is used:

1. Output Redirection: In shell commands, >> is used to append the output of a command to a file. For example, echo "Hello" >> output.txt will add "Hello" to the end of output.txt without overwriting its existing contents.

2. Bitwise Right Shift Operator: In programming languages like C, C++, and Python, >> is used as a bitwise right shift operator. It shifts the bits of a number to the right by a specified number of positions. For example, x >> 2 shifts the bits of x two places to the right.

3. Stream Manipulation: In some programming contexts, >> can be used for stream extraction, particularly in C++ with the iostream library. For example, cin >> variable; reads input from the standard input stream into variable.

The specific meaning of >> will depend on the context in which it is used. If you have a particular scenario in mind, please provide more details for a more precise explanation.
