How does '>' differ from '>>'?

The > and >> symbols are both used for output redirection in the command line, but they serve different purposes:

1. > (Output Redirection):

   • The > symbol is used to redirect the output of a command to a file, overwriting the file if it already exists.
   • Example:

     echo "Hello, World!" > output.txt

     This command will create (or overwrite) output.txt with the text "Hello, World!".

2. >> (Append Redirection):

   • The >> symbol is used to append the output of a command to a file, preserving the existing content of the file.
   • Example:

     echo "Hello again!" >> output.txt

     This command will add "Hello again!" to the end of output.txt without deleting the existing content.

In summary, > overwrites the file, while >> appends to it.
