4. Verification Script

This is a Korn shell script to verify beautifier program. Requires "pdksh*.rpm" from Linux 'contrib' cdrom. Save this file as 'text' file and chmod a+rx on it. You can re-write this shell script in PERL so that you can use it on Window 95/NT or MSDOS. Uncomment the PRGM variable to point to bcpp, cb or indent


#!/bin/ksh

# Verification program to check C++ Beautifiers 'bcpp', 'indent' or cb
