This lab introduced me to the difference between a relative pathname and an absolute pathname. I learned which type of pathname to use in different scenarios so my commands can be more efficient.

One challenge I faced was remembering the command that displays only the last five lines of /etc/group and understanding how file globbing works (using wildcard characters). I had to look back at my notes to recall it. Overall, this lab helped me better understand the Linux filesystem and the use of arguments.
