This lab introduced me to using the vi editor to modify and manage a text file. It included copying a system file, opening it in vi, and performing editing tasks such as inserting text, navigating through the file, searching for words, deleting content, copying and pasting lines, and replacing text. I faced challenges switching between command and insert modes and remembering vi shortcuts. Overall, it strengthened my ability to use vi and showed how efficient command-line text editing can be.
