💬Answer

Command Lookup: The shell resolves the binary location (usually /usr/bin/ls).
Process Spawn: The shell calls fork() to clone itself and execve() to load the ls code into memory.
Kernel Execution: The kernel executes the process and assigns virtual memory space.
Filesystem Read: ls calls system routines (like getdents) requesting the directory contents from the kernel.
Output Rendering: The kernel retrieves data blocks from the filesystem and outputs results to your terminal window.
