O_ops: Better Logging To Solve Problems

Logging helps in pinpointing the code block that threw an error. Only if they are used correctly. During once such failure, a guy noticed that a script lacked logging and ever promptly promoted the updated script with better logging. A part of the script is shown below.

Script before:

1>>${LOG} 2>>${ERRLOG} ${BINPATH}/${PROGRAMNAME}
if [ $? -ne 0 ]; then
  print "ERROR: Something failed"
  exit 101
fi

Script after:

1>>${LOG} 2>>${ERRLOG} ${BINPATH}/${PROGRAMNAME}
echo "Program completed successfully."
if [ $? -ne 0 ]; then
  print "ERROR: Something failed"
  exit 101
fi

The change made it a “better” script for sure - it never failed again!
