Homework & Coursework Questions

I want to see the algorithm of how you understand the entered arguments;
I may be wrong but I understand as:
means whatever argument is entered, you have to check if it exits first in $HOME
then check if its a directory..
I dont get.... (??)
look around on this forum we all have our way to do things (may not be cp... for instance what happens if the file, or directory (subdirectory etc...) is a link? )

You have now plenty of information to work on!

Good luck

ok thanks , i will try

I hope so!

We will be here to help you, but the work - you are to do!
What Im pointing at is an explicit algorithm is readable for anyone here (no language dependant). A bad program takes some time even for us to understand what is going on especially if the writer did no documenting in it...
Here we can show before the code part, if its good or wrong or if you forgotten something...

Will we see the beginning in an hour time?...

DIR=/dir/$(date +%y%m) */ DIR, folder or directory create than get the following directory, $dir and get the date,,, i m not sure if thats possible

[ -d "$DIR" ] || mkdir "$DIR" if the directory not exist, create one, the name will be backup... how i put at directory home...?? (-d true if file exist and is a directory)

so now i need to know if the directory exist, i m sure...

if exist i can copy the dir( $ dir) , in first to a temporary folder??

"(may not be cp... for instance what happens if the file, or directory (subdirectory etc...) is a link? )",, if i use the echo dir.. can be..sorry for my stupid questions... but if i m learn i need ask... :$

#!/bin/bash
DIR=/dir/$(date +%y%m) */ DIR, folder or directory create than get the following directory, $dir and get the date,,, i m not sure if thats possible

[ -d "$backup" ] || mkdir "$backup" if the directory not exist, create one, the name will be backup...

for (echo pwd)
do
cp /usr/home/backup

that is my best.. how i can put date and time... i dont idea how..

The best/hard way to learn is to test and see what is going on...
1) create a dir, add a few things, create a subdir, do the same..., in dir create a symbolic link to subdir calling it mylinkdir.
2) cp how you can all what you just did in mybckdir

3) analyse the result:
do I have all?
And the subdir?
what about the perms and ownership
what about the time stamps of copied stuff?
what can you say about the link?

I see you are still trying to code without a beginning of algorithm/procedure... so dont expect much help from you peers
