Shell Programming and Scripting

I need to do a work to my job, but i m new in script shell, someone can help with this..


Description



Bsafe The command creates a backup directory of each month at the command line (arguments of the script). The names of directories to copy will always be specified for the home user. To save copies of the script uses a specific directory, now called the backup directory. If the backup directory does not exist, the script should create it. Within the backup directory, the script should create a directory for each backup done (use a different name every time). Within this directory (the copy of the instant), each directory passed as argument of the script should be copied, including sub-directories and files, preserving dates and times of access and modification of them. Of course, the backup directory should not be copied into itself.




Thanks

Do you have an idea of where to put that backup directory (should it be in the user's home?) what name you want to give to the different subdirs (date? year-month?).
Should all the files be copied or only the modified ones?

Using cp, something like :

Code:

#!/bin/bash
DIR=base/path/of/your/backup/dir/$(date +%y%m)
[ -d "$DIR" ] || mkdir "$DIR"
for D in $@ # gets the arguments of the command line
do
    cp -av ~/"$D" "$DIR/$D"
done

I could be wrong, but that sounds a lot more like homework than a task delegated by a boss.
