Your assignment is to write a shell script invoking awk to produce class rosters. The schedule file is a copy of the USM fall schedule from a previous year. Most schedule entries are single lines, but some are 2 lines and a few are 3 lines.
Continuations are identifiable by blanks in the registration code field.
The students file is a collection of made-up names. Any similarity to real names is unintentional and surprising. The regs file is a set of registration records. Each record has a Social Security number and a registration code, and means that the identified student is enrolled in that class. The first step in processing a request is to use awk to print the course information.
