• Generate a permuted index where the first field of each line is an index reference:

ptx --references path/to/file

• Generate a permuted index with automatically generated index references:

ptx --auto-reference path/to/file

• Generate a permuted index with a fixed width:

ptx --width=width_in_columns path/to/file

• Generate a permuted index with a list of filtered words:

ptx --only-file=path/to/filter path/to/file

• Generate a permuted index with SYSV-style behaviors:

ptx --traditional path/to/file
