Basic usage and syntax

The basic syntax for the sdiff command is as follows:

sdiff [options] file1 file2

Where:

• file1 and file2 are the two files to be compared
• options are the optional arguments that can be used to customize the output

Examples of common use cases

The sdiff command can be used for a variety of tasks. Here are some common use cases:

• -s: Output only the differences between the two files
• -w: Output the differences in a formatted table
• -y: Output the differences with the two files side by side
• -z: Output the differences in a compact format

Examples in real-world scenarios

• Make sure the files you are comparing are in the same format (text or binary)
• Make sure the files are in the same directory before running the command
• If the output is too long, use the -z flag to output the differences in a compact format
• If you are comparing two directories, make sure you use the -r flag to recursively compare the subdirectories
• If the output is empty, make sure the files are not identical
