What You Need to Do

Create the script hw7.sh with Unix commands that will do what is described in the steps below
This file must be in an hw7 directory under your hw directory

Setup

From your home directory go to your it244 directory
```
cd it244
```
Go to your hw directory
```
cd hw
```
Create an hw7 directory
```
mkdir hw7
```
Enter this new directory
```
cd hw7
```
Create hw7.sh
```
nano hw7.sh
```

Specification

Create the file hw7.sh inside your hw7 directory using nano
Write the Unix command to perform the action specified by each step
Be sure to write a Step comment before the Unix commands for each step

This step requires you to write two commands on two different lines.
In the first command copy bother10.sh from /home/ghoffman/course_files/it244_files to your current directory, which should be hw7.
In the second command run bother10.sh, redirecting output to /dev/null, in the background.
Be sure you copy and run bother10.sh, NOT bother.sh.
Run a command that shows the job number of the process running bother10.sh.
Run a command that shows the process ID of the process running bother10.sh.
Copy the script make_foo.sh from ~ghoffman/course_files/it244_files to your current directory.
Run this script.
Perform a long listing of all files whose name starts with the string "foo" using meta-characters.
Using meta-characters, perform a long listing of all files whose name starts with the string "foo", followed by a single character, followed by .txt .
Using meta-characters, perform a long listing of all files whose name starts with the string "foo", followed by a single digit, either 1, 3 or 5, followed by .txt .
Using meta-characters, perform a long listing of all files whose name starts with the string "foo", followed by a single digit from 1 through 5 followed by .txt .
Do this using the range feature of one of the meta-characters.
Using meta-characters, perform a long listing of all files whose name starts with the string "foo" followed by a single digit, not 1, nor 3 nor 5, followed by .txt .
Using meta-characters, perform a long listing of all files whose name starts with the string "foo" followed by two digits followed by .txt .
Using meta-characters, perform a long listing of the files foo21.txt, foo25.txt and foo29.txt. This must be done using a single command.

Testing

There are two tests that your should run on your script
The first test checks for Unix errors
Run bash on your script like this
```
bash hw7.sh > /dev/null
```
This will run your script but will only show error messages
If you see nothing, your script has passed this test
The second test checks your Step comments

Run it like this

~ghoffman/code/it244_code/testing_scripts_it244/step_comment_check.sh

If your Step comments are wrong you will lose points
