- Compare 2 files:

`sdiff {{path/to/file1}} {{path/to/file2}}`

- Compare 2 files, ignoring all tabs and whitespace:

`sdiff {{[-W|--ignore-all-space]}} {{path/to/file1}} {{path/to/file2}}`

- Compare 2 files, ignoring whitespace at the end of lines:

`sdiff {{[-Z|--ignore-trailing-space]}} {{path/to/file1}} {{path/to/file2}}`

- Compare 2 files in a case-insensitive manner:

`sdiff {{[-i|--ignore-case]}} {{path/to/file1}} {{path/to/file2}}`

- Compare and then merge, writing the output to a new file:

`sdiff {{[-o|--output]}} {{path/to/merged_file}} {{path/to/file1}} {{path/to/file2}}`
