Lab 5 Managing files and directories

Overview

This lab will introduce you to creating and managing directories and files using the bash command line interface. All commands in this lab are to be run using your normal user account only, without the use of sudo or su.

Tasks

In your home directory, make a new directory named lab5.
```
mkdir ~/lab5/
```
Change to that directory and use curl with tar to retrieve some files from the web for us to work with.
```
cd ~/lab5/
curl https://zonzorp.github.io/COMP2018/files.tgz|tar xzf -
```
Use ls to explore the files you extracted.
```
ls
ls -R
```
Use the tree command to see what the directory structure created looks like.
```
tree
```
In your home directory, make a new directory called backups. Copy the complete tree of files you just downloaded to your lab5 directory to the backups directory. Use tree to verify that your backup created what you expected. Do not modify anything in the backups directory for the remainder of this lab.
```
mkdir ~/backups
cp -r ~/lab5 ~/backups/
tree ~/backups
```
Use the file command to find out what the content of the files in the catfiles directory are and rename those files to have appropriate extensions.
```
cd ~/lab5/catfiles
file *
mv <a filename without any extension> <a filename with an appropriate extension> **Repeat as needed**
```
Make a new directory in lab5 to hold text files and name it txts. Move the text files from the catfiles directory to the txts directory.
```
mkdir ~/lab5/txts
mv ~/lab5/catfiles/*.txt ~/lab5/txts/
```
Make a new directory in lab5 to hold image files and name it images. Make a new directory to hold jpg files in the images directory and name it jpgs. Make another for png files in the images directory and name it pngs. Move the jpg files from the catfiles and whoisit directories to your new jpgs directory and the png files from the catfiles directory to your new pngs directory. Remove the old catfiles and whoisit directories that should now be empty. Use the tree command to verify you have completed these commands correctly.
```
mkdir -p ~/lab5/images/jpgs ~/lab5/images/pngs
mv ~/lab5/*/*.jpg ~/lab5/images/jpgs/
mv ~/lab5/*/*.png ~/lab5/images/pngs/
rmdir ~/lab5/catfiles ~/lab5/whoisit
tree ~/lab5
```
Make a new directory in lab5 to hold links to all your image files and name it webpics. Create symbolic links for all the jpg files and png files in your new webpics directory. Run the tree command one more time to verify you got the links you should have.
```
mkdir ~/lab5/webpics
cd ~/lab5/webpics
ln -s ../images/*/* .
tree ~/lab5
```
Open your file manager and browse to your lab5 directory. Try viewing the directories you have created to see what files are there using the GUI.

Submission of Results

Capture screenshots of the terminal window showing your prompt, commands, and as much of the output for each command as fits in the window with your command still showing. Submit a single PDF file to blackboard containing your screenshots in the order they were performed, along wityh your responses to the questios asked in the lab.
