Perl, out with the old, in with the new?

[John Love_3]

I have a D class server with HP-UX 11.0 and when I do a perl -v I get:
#perl -v

This is perl, version 4.0

$RCSfile: perl.c,v $$Revision: 4.0.1.8 $$Date: 1993/02/05 19:39:30 $
Patch level: 36

Now, I have a DEPOT file with Perl 5.6.0 and when I install it I still get Perl 4.0 with the perl -v command.

How do I get rid of the 4.0 and have the 5.6.0 version work? The install goes fine, no errors.

Help please. I need a web server that uses this newer version of perl (Apache is already installed on this server).

Thanks!

The perl version 4 is installed in /usr/contrib/bin I think. The perl version 5.6 that you just installed is installed in /opt/perl5/bin.

There are 2 things that you can do:

1a) rename (mv) /usr/contrib/bin/perl to /usr/contrib/bin/perl.old

1b) link /usr/contrib/bin/perl to /opt/perl5/bin/perl (ln -s /opt/perl5/bin/perl /usr/contrib/bin/perl -- I think I got the order right on the link, I'm not at work so I can't double check).

2) Modify your path so that /opt/perl5/bin appears before /usr/contrib/bin

Either should work for you.

Good luck.

I went with option 1 since I wasn't sure how to change the order of my path.

It works perfectly and the syntax was exactly right.

Thanks a lot!

Perl 4 is supplied just for the q4 program and a few references in SAM. To adjust the $PATH value, edit /etc/PATH. /etc/profile sets $PATH using this file. Well written shell (and perl) scripts will have the path in the first line:

#!/opt/perl5/bin/perl
