Ken Prows commented on SOLR-327:
--------------------------------
On Solaris 10 I also ran into a problem with the date command. The -d option
does not exist for the Solaris version of date. This causes the snappuller
script to fail. In order to fix this, I made the below changes. Note that I
made these changes off of the latest version from trunk (revision 556910) since
there were already some Solaris fixes there.
CHANGED:
rsyncStart=`date +'%Y-%m-%d %H:%M:%S'`
startTimestamp=`date -d "$rsyncStart" +'%Y%m%d-%H%M%S'`
rsyncStartSec=`date -d "$rsyncStart" +'%s'`
TO:
rsyncStartSec=`perl -e 'print time'`
startTimestamp=`perl -MPOSIX -e 'print POSIX::strftime("%Y%m%d%H%M%S",
localtime(time))'`
CHANGED:
rsyncEnd=`date +'%Y-%m-%d %H:%M:%S'`
endTimestamp=`date -d "$rsyncEnd" +'%Y%m%d-%H%M%S'`
rsyncEndSec=`date -d "$rsyncEnd" +'%s'`
TO:
rsyncEndSec=`perl -e 'print time'`
endTimestamp=`perl -MPOSIX -e 'print POSIX::strftime("%Y%m%d%H%M%S",
localtime(time))'`
----
As a side note, I'd like to see the scripts converted from bash to perl for
better portability. If there is any interest in that, I'd like to help take
that on.

> 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.
