ptx

Generate a permuted index of words from one or more text files. More information: https://www.gnu.org/software/coreutils/ptx.

• 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}}
