• Because you don't have access to the VCL.
• Because something is wrong and you can't get the Glide image in the VCL

If you are the learner, you need to get help from a Linux user to get this set up.

The setup described here should work with all Linux distros. (The VCL Glide image uses CentOS Release 7.9) But not all Linux systems have the tree command installed, so add it via yum or apt, as appropiate, if it's not there. Everything else should be there. (We have found that the tree command is very helpful for students to grasp the tree-structure of computer directories.)

The directory tree for the /home directory is

/home
|-- hes
|   |-- a
|   |-- b
|   |-- c
|   |   |-- w
|   |   |-- y
|   |       |-- z
|   |-- first-cat
|   |-- first-file
|-- mtr
    |-- onlyonefile

4 directories, 7 files

So the user's home directory (here it's hes) and also the subdirectories c and y need to be set up. Also the /home/mtr directory.

Then fill in the files - whose contents are:

$ cat a
lots of characters lots of characters lots of characters
lots of characters lots of characters lots of characters
lots of characters lots of characters lots of characters

$ cat b
This file doesn't have anything in it about bees.

$ cat w
123.45,546.7
32.1,458.904

$ cat z
This file is down in your directory tree. It's in a subdirectory of a
subdirectory of your own directory in /home

$ cat first-cat 
Muezza

$ cat first-file 
Is this the first file, or the second, or ...? Does anyone care?
Here's the second line of this file.
And the third.

$ cat onlyonefile 
which contains nothing
at all of interest

This should show you the 4 directories and 7 files as at the top of this web page.
