$PATH is an environment variable that stores the paths that the shell searches when searching for executable files. Since they are separated by : (colon), by selecting : with the -F (field separator) option of the awk command, it is split into individual paths, and the NF (number of fields) variable displays the paths for each field. If you simply want to display the paths, just specify $PATH as an argument to the echo command as shown below.
