Hello and I need help like in yesterday
I haven't been using linux very long( and when I say that its only been about 1 week for me) I was told to do the following:
Create a Bash script that will copy all the files and subdirectories in one directory to a newly created directory. You may name the receiving directory anything you like. Ensure you use the proper syntax to allow auto-execution from the command prompt.
Here's the problem, linux is suppose to work like windows but a little different. I name the file wrong and I tried to remove it. I recieved an error saying the directory was busy. (I never knew that a directory could be busy and I know I used the command rmdir scripts which was what I named it but it didn't work) so i decided to make another file. I didn't want to make another directory, just a file but I don't know how to do that I just know how to make directories, unless that is considered a file.
As far as the bash script is concerned, I don't even know where to start except on what I was told to do and that is this:
#!/bin/bash
dir > /cp dir >>
really don't know if that is it or what, and it makes no sense to me. what does that first line of the script mean anyway? I am so confused and I feel dumber than a door knob. Please help
