OK. Finally, here it is. The following Korn shell script provides a way to read a data file (named data), extract data items from that file, create a menu of the data items, and allows the user to interactively request the data associated with each menu entry. It actually provides two sample solutions for this problem and runs both solutions so the user can see the differences in behavior.
The first method is an awk script. It only uses features in awk that are included in the POSIX Standards. (Note that on Solaris systems, you'll need to use nawk or /usr/xpg4/bin/awk rather than /usr/bin/awk.)
The second method is a Korn shell script. It makes use of a few features that are not available in old versions of ksh; you'll need a version newer than November 16, 1988. It also makes use of some features that are not required by the POSIX standards.
The awk and ksh scripts use the same variable names. A summary of the variable names and their uses is provided in comments between the two scripts.
Here it is:
and here is the data file I used to test it:
The first part of it is data that was provided in the 1st message in this thread, but adds some spaces and tabs at the beginning and end of some non-empty lines, and adds some blank lines to test the ability of these scripts to handle blank lines, leading whitespace, and trailing whitespace.
I hope this helps you compare some of the features of awk and ksh for performing similar tasks.
