In your menu design,when users enter P or p, the application should print a phone list. Theawk program offers a good example of how the UNIX/Linux shell programmer canaccelerate development because a single awk command can select fields from many records and display them in a specified format on the screen. In this project, you develop the phlist1 script and use awk to display a phone list.

To create the phlist1 script:

1. From the source directory, use the editor of your choice to create the phlist1 script as follows:

2. Save the file and exit the editor.

3. Give the file execute permission by typing chmod a+x phlist1 and pressing Enter. Run the script by typing ./phlist1 and pressing Enter. (See Figure 6-19.)
