man page autocomplete

Raw

mancomplete.md

Basic bash completion for man command.

Known manual page names
man options

More could be added especially for the options for each flag but I rarely use them.

Instructions

Either have this inside your ~/.bashrc or save it somewhere and source it in your ~/.bashrc

#!/bin/bash

_man ()
{
  local CWORD
  CWORD="${COMP_WORDS[COMP_CWORD]}"
  # printf 'current word "%s"\n' "$CWORD"  # For debugging
  case "$CWORD" in
    -* ) readarray -t COMPREPLY < <(man --help | grep -oP '\-[\w?\-]+');;
    *) readarray -t COMPREPLY < <(man -k . | sed -n "/^$CWORD/ s/ .*//p");;
  esac
}
complete -F _man man
