Re: Which version is this module?

[Abigail-II]

I like

    perl -MCPAN -e 'CPAN::Shell -> m (shift)' MODULE

which not only gives the installed version number, but also the version number of the newests version on CPAN.

Nice one. But you need to know what you're looking for. For example:

$ perl -MCPAN -e 'CPAN::Shell -> m (shift)' DateTimeCPAN: Storable loa
+ded ok
Going to read /Users/liz/.cpan/Metadata
  Database was generated on Fri, 13 Feb 2004 01:50:02 GMT
Module id = DateTime
    DESCRIPTION  A complete, easy to use date and time object
    CPAN_USERID  DROLSKY (Dave Rolsky <[e-mail]>)
    CPAN_VERSION 0.20
    CPAN_FILE    D/DR/DROLSKY/DateTime-0.20.tar.gz
    DSLI_STATUS  bmpO (beta,mailing-list,perl,object-oriented)
    INST_FILE    (not installed)

is a module that I don't have installed: CPAN has 0.20. Whereas:

$ perl -MCPAN -e 'CPAN::Shell -> m (shift)' ifdef   
CPAN: Storable loaded ok
Going to read /Users/liz/.cpan/Metadata
  Database was generated on Fri, 13 Feb 2004 01:50:02 GMT
Module id = ifdef
    CPAN_USERID  ELIZABETH (Elizabeth Mattijsen <[e-mail]>)
    CPAN_VERSION 0.03
    CPAN_FILE    E/EL/ELIZABETH/ifdef-0.03.tar.gz
    MANPAGE      ifdef - conditionally enable text as code within pod 
+sections
    INST_FILE    /usr/local/lib/perl5/site_perl/5.8.3/ifdef.pm
    INST_VERSION 0.03

shows that I have the "ifdef" module installed. Note that both the "CPAN_VERSION" as well as the "INST_VERSION" are shown now.
