In the source code path, run

$ ./configure
$ make

Now, you should get the binary executable, run

$ ./unp

to get the list of programs.

Programs:
 daytimetcpcli   1.5    TCP daytime client
 daytimetcpsrv   1.9    TCP daytime server
 byteorder       3.10   Program to determine host byte order
 daytimetcpsrv1  4.11   Daytime server that prints client IP address and port.
 tcpserv01       5.2    TCP echo server (improved in Figure 5.12)
 ...

To run a program you want, for example, byteorder, you can type

./unp byteorder

or you can use the figure number

./unp 3.10

The most convinient way is to use symbolic link

$ ln -s unp byteorder

and run

$ ./byteorder

Some library functions have multiple versions, run

$ ./apue -f

to get the list of library functions.

 ...
 # str_echo      5.3    echoes data on a socket
                 5.17   str_echo function that adds two numbers
                 5.20   str_echo function that adds two binary integers
 # str_cli       5.5    client processing loop
                 5.14   str_cli that calls writen twice
                 5.19   str_cli that sends two binary integers to server
                 6.9    str_cli using select
                 6.13   str_cli using select that handles EOF correct
 ...

Functions start with '#' are multi-version functions.
Use environment variable to specify the function.
For example, to run a server add two integers:

$ str_echo=5.17 ./unp 5.12 

and on another terminal, run

$ ./unp 5.4 127.0.0.1
