SOLUTION....

🔹 1. Command Redirection

In Linux, redirection is used to control where the input and output of a command go (file, screen, or another command).

(a) Standard Output Redirection (> and >>)

  • > : Redirects output to a file (overwrites).

  • >> : Redirects output to a file (appends).

Example:

(b) Standard Input Redirection (<)

  • Takes input for a command from a file instead of keyboard.

Example:

(c) Standard Error Redirection (2>, 2>>)

  • Redirects error messages to a file.

Example:

(d) Redirect Both Output and Error (&> or > file 2>&1)

  • Redirects both stdout and stderr to the same file.

Example:

(e) Here Document (<<)

  • Redirects a block of text to a command.

Example:

(f) Here String (<<<)

  • Redirects a single string as input.

Example:

🔹 2. Piping (|)

  • A pipe (|) sends the output of one command as input to another command.

Example:

Multiple Pipes
