The command sdiff -Z ${filename1} ${filename2} is used to view the differences between two files and display them side by side.

Here's a breakdown of each component:

• sdiff is the command-line tool used for comparing files.
• -Z is an option provided to the sdiff command, which tells it to compress multiple spaces into a single space when comparing the files.
• ${filename1} and ${filename2} are variables representing the names of the two files you want to compare. It's assumed that you would replace these variables with actual file names when running the command.

When executed, this command will compare the contents of the files ${filename1} and ${filename2} and display the output in a side-by-side format. Differences between the files will be indicated using certain characters such as | to highlight changes in individual lines or blocks of text.
