Create fileABC, that combines three files, starting with fileA , then fileB, then fileC
2. Use echo, add “this is a new last line” to the end of the file
Expert Answer
# cat command used to combine several files into a single file
cat fileA fileB fileC > fileABC
echo “this is a new last line” >> fileABC
#if you use > instead of >> in the above command, then the fileABC is overwritten.
