Use a while loop to read each line in the file modified_etc_passwd directly and process each line as follows:

Use a combination of the echo and cut commands to assign the contents of the home directory field of the current record to a variable called homedir

Use a combination of the echo and cut commands to assign the contents of the username field to a variable called username

If homedir exists as a directory o Use a combination of the echo and cut commands to assign the contents that appears before the + of the GECOS field to a variable called fullname o If /home/STUDENTS/majors/username exists

Echo fullname and append to the file majors.txt Example: echo $fullname >> majors.txt o Otherwise

If /home/STUDENTS/nonmajors/username exists

Echo fullname and append to the file nonmajors.txt

Otherwise

Echo username and append to the file not_student.txt

Otherwise o Echo the current record and append to the file no_homedir.txt When finished, execute your script and create 4 clear output files.
