This is the solution I ended up going with:
#########################################
file=data.txt #sets variable file to data.txt
numlines=`wc -l $file | awk '{ print $1 }'` #sets $numlines to the number of lines in $file
r=0 #sets $r to 0
#########################################
while [ $r -le $numlines ]; do #runs loop as many times as there are lines in the file
line=`cat $file | head -$r | tail -1` # $line is equal to the data on the particular line we
## are on in the loop
if [[ $line = *.* ]] #if $line contains anything than a period than anything else
then
echo "-a" $line >> goodfile.txt # prints -a plus the data previous on that line
else
echo >> goodfile.txt # if it does not contain anything a period anything else prints a
## blank line to goodfile.txt
fi
It will work of course... but you could have done it all with awk. I would encourage you to read-up on it and see how the tool could have been applied to the problem.
I did use awk, where needed: numlines=`wc -l $file | awk '{ print $1 }'`
That was all it was needed for, the rest was processed through a while loop. ;p
