I’ve found a little mistake in the 8th question about cut command.

In the first example, the -c option is used and it extracts characters not columns as stated.

In reply to Siddarth. I'm a bit late to the party, but something more concise might be:

i=1
until [ $i -gt 6 ];
do
  printf "%d %d %d %d\n" $i $((i+1)) $((i+2)) $((i+3))
  : $((i++))
done

In reply to zen. The way the question was asked wasn't very clearly stated to accomplish the use of the command ls and echo to answer it in the affirmative and explain. The question should have been, "Is it possible to list the file and directory names of a given 'parent directory' using a command other than 'ls?'" Yes, the use of "echo *" will perform the equivalent of a plain "ls."
