Explain Linux I/O redirection

In Linux, IO redirection is a way of changing the default input/output behavior of a command or program. It allows you to redirect input and output from/to different sources/destinations, such as files, devices, and other commands.

Here are some common examples of IO redirection:

• Redirecting Standard Output (stdout): ls > filelist.txt
• Redirecting Standard Error (stderr): ls /some/nonexistent/directory 2> error.txt
• Appending to a file: echo "hello" >> myfile.txt
• Redirecting Input (stdin): sort
• Using Pipes: Pipes ("|"): ls | grep ".txt$"
