1. The problem statement, all variables and given/known data:
Write a script that allows the user to print the first n lines or the last n lines of every file in the directory specified by the argument. e.g. lshead -head 2 Documents will print the first two lines of every file in the documents directory.
2. Relevant commands, code, scripts, algorithms:
Head command is used in this command as well as the tail command.
3. The attempts at a solution (include all code and scripts):
I have run it and it comes up with this error:
head: Documents: invalid number of lines
I don't understand why it isn't working, I have even consulted friends on this and even they can't understand why it isn't working.
4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
