Colour schemes can be customized. > More information: . - Compare files: `colordiff {{file1}} {{file2}}` - Output in two columns: `colordiff -y {{file1}} {{file2}}` - Ignore case differences in file contents: `colordiff -i {{file1}} {{file2}}` - Report when two files are the same: `colordiff -s {{file1}} {{file2}}` - Ignore white spaces: `colordiff -w {{file1}} {{file2}}`
