Compare the differences between and optionally merge 2 files. More information: https://manned.org/sdiff.

• Compare 2 files:
  sdiff {{path/to/file1}} {{path/to/file2}}
• Compare 2 files, ignoring all tabs and whitespace:
  sdiff -W {{path/to/file1}} {{path/to/file2}}
• Compare 2 files, ignoring whitespace at the end of lines:
  sdiff -Z {{path/to/file1}} {{path/to/file2}}
• Compare 2 files in a case-insensitive manner:
  sdiff -i {{path/to/file1}} {{path/to/file2}}
• Compare and then merge, writing the output to a new file:
  sdiff -o {{path/to/merged_file}} {{path/to/file1}} {{path/to/file2}}
