# Create a BASH script (bartsimpson.sh) that asks for a phrase such as ÒI will not 
# make my computer go through endless loopsÓ that then iterates 100 times and outputs # the 100 phrases to a file chalkboard.dat. 
# Extension: Use a for loop, while loop and if loop to generate the same output. 
# Name the scripts bartsimpson-for.sh, bartsimpson-while.sh, bartsimpson-if.sh
# that output to chalkboard-for.dat, chalkboard-while.dat and chalkboard-if.dat.
