Version of Perl on HP-UX Server

[Gillian Gentile]

How can I find out what version of Perl that is on an HP-UX Server on version 10.2? Our SA did not know, and I am at a loss. I tried to use the perl -V command, but got error "Unrecognized switch: -V".

Hi,

Looks like you are using the /usr/contrib/bin/perl which is version 4.0 and doesn't support the "-V" option.

You will have to use "-v" to get the version.

I would highly recommend you to upgrade to a newer version.

You can download it from
http://hpux.cs.utah.edu/hppd/hpux/Languages/perl-5.6.1
or
http://hpux.ee.ualberta.ca/hppd/hpux/Languages/perl-5.6.1

-HTH

If you have Q4 (part of installed along with the latest Q4 patch, PHCO_20262 then you probably also have perl in /usr/contrib/Q4/bin/perl and this is version 5.005_02.

For instance,

# whereis perl
perl : /usr/bin/perl /usr/contrib/bin/perl

# /usr/bin/perl -v
# /usr/contrib/bin/perl -v

Hope this helps,

Thank you so much for your responses. I was able to find the version using perl -v. We are on version 4.0. Thanks for the download site links as well!

One thing to remember: If you install the version of PERL you get from the Porting Centre, it gets installed in /opt/perl5 so you will need to make sure you specify the correct path to PERL if you use it in a script.

Hello,
On the question of PERL upgrades. Is swinstall a requirement to get it on the box, or can I simply lay down the binaries and run?
If it is swinstall, does it require kernal changes/reboot? I'd like to lay it down without a service interruption. Thanks

[Santosh Nair_1]

You should be able to lay down the binaries and it should work, but remember to copy over the library routines also, which is usually named something like lib/perl5.

Just download it and run the interactive version of swinstall. No reboot is necessary.
About the only thing you have to do is a symbolic link:
ln -s /opt/perl5/bin/perl /usr/bin/perl
and then make sure that /usr/bin precedes /local/contrib/bin (where the old perl is).

If you download the precompiled binaries from the porting center, then you can just install them via swinstall. This does not do any kernel changes nor does it required a reboot. It will be installed to /opt/perl5 so the path to the perl executable is /opt/perl5/bin/perl.
