LWM-Linux/06 - Linux File Operations/IO Redirection and Piping.md

Certainly! Let's dive into the concepts of I/O redirection and piping in Linux Mint:

1. I/O Redirection:

   • Standard Input (stdin), Standard Output (stdout), and Standard Error (stderr) are essential file descriptors for communication between programs and the outside world.
   • stdin: Default input source (usually keyboard input).
   • stdout: Default output destination (typically the terminal).
   • stderr: Alternative output for errors.
   • We can redirect these streams to/from files or other commands.

2. Redirection Operators:

   • >: Redirects stdout to a file (overwrites existing content).

     ls > files
     

   • >>: Appends stdout to a file.

     ls -1 *.txt >> files
     

   • 2>: Redirects stderr to a file.

     command_that_might_fail 2> error.log
     

3. Piping (|):

   • Connects the stdout of one command to the stdin of another.
   • Useful for chaining commands:

     ls | grep "pattern"
     

Remember, mastering I/O redirection and piping enhances your command-line skills! Feel free to explore further or ask more questions. 😊🚀¹²⁴
