in reply to What is perldoc -lf doing?

perldoc -f NAME always lists results found in perlfunc.pod and perlop.pod.

That's what -l is telling you, for every possible NAME.

The builtin function grep is finally only found in perlfunc , but operators like == only in perlop .

D:\Users\lanx>perldoc -lf ==
C:\Perl_64\lib\pods\perlfunc.pod
C:\Perl_64\lib\pods\perlop.pod

D:\Users\lanx>perldoc -f ==
  Equality Operators
    Binary "==" returns true if the left argument is numerically equal
+ to
    the right argument.

    What am I missing with my install?

No documentation for perl function '==' found

      It's probably MSWin specific. It doesn't work for me either, not even in blead: 
      $ perldoc -f ==
No documentation for perl function '==' found

        Nope, it's missing on both platforms.

        X:\>perldoc -f ==
No documentation for perl function '==' found

X:\>perl -v

This is perl 5, version 24, subversion 1 (v5.24.1)

        My first working test was with Win/5.16 (later Linux/5.18).

        Most probably a regression between 5.18 and 5.24, perlop is still showing the entry.

      Probably a glitch on console level.(?)

      I used Windows and you Linux and bash tries to use == for its own syntax.(untested)

      ( You know Perl was built for UNIX ... Ehm wait... ;)

      update

      Nope: works with Ubuntu and Perl 5.18, so probably a bug with newer Perl versions.

        Perldoc has been broken for at least 4 years and no one noticed? How does that get past the testers? perldoc -f == works on 5.18 but not 5.20 or higher on osx.
