Ken Prows commented on SOLR-327:
--------------------------------
I don't think there is anything the scripts do that couldn't be done using the
ActivePerl on windows. Hard links work in windows for NTFS volumes. There are
even cpan modules that provide an rsync API.
> shell scripts failed to run on Solaris 8 (and probably other non recent UNIX)

> Key: SOLR-327
> URL: https://issues.apache.org/jira/browse/SOLR-327
> Project: Solr
> Issue Type: Bug
> Reporter: Paul Sundling
> Priority: Minor
>
> There are several places where commands used are incompatible with older UNIX
> versions, even though these capabilities are present. There are ways to
> rewrite the shell scripts to be compatible with these older versions.
> The first example is the use of pgrep. Older machines will have grep, egrep
> and fgrep, but NOT pgrep. I've been doing UNIX for well over a decade and
> never heard of pgrep, although it is installed on my home server apparently.
> :)
> There are also enhancements like the use of 'cp -l'. This could be
> accomplished with the 'ln' command instead on older UNIX versions. Since
> it's also used recursively in snapshooter, which 'ln' doesn't support, it
> makes the command more complex.
