Note: Remember to include #!/bin/bash as the first line of your script.

Save the file and type your file name to execute.

Source Programs

<Insert your source code here.>

Output Results

<Insert the output here. Use a screenshot of the output with the input requirements specified in the assignment.>

Linux® Script 2

Requirements

In the same folder as last week, create a new file called week3prog2[name].scr.

Change the permissions on this new file to add the execute bit for user, group, and owner.

Edit your new file using Gedit or VI and change it so it performs the following actions:

• Using a line after #!/bin/bash, take the output of the ps –e command and pipe it to the sort command
• After it has been piped to the sort command, redirect that output to a file called psfile
