perl installation on HP-UX

Hi,
thanks all for your comments but I did change the files in /etc.
This didn't made any difference.
Also, in the user homedir I looked at the files .profile.
In it there was this text:
#
# default login behaviour
#
# Take all environment settings from the central source.
#

if [ -f /etc/opt/exp/profile.central ]
then
  . /etc/opt/exp/profile.central
fi

So I looked under etc/opt/exp/
in the profile.central file I also adapted the PATH, but no luck....

I'm clueless what I can do next...
Thanks

Those files are normally where the global path would be set.  Maybe HP, or your specific setup, is using something else.  To search for all files that might set the path, run this:
    find /etc -type f -exec grep -H PATH {} \;

Then look in all of those files to see which are setting the path.
To see your current path, use:
    echo ${PATH}

Apparently the -H switch is invalid for my version of HP-UX.
So I ran
 find /etc -type f -exec grep -e PATH {} \; > aa.txt
Which resulted in this file

The -H option causes grep to include the name of the file.  From your aa.txt file, I can see several places where the PATH is set, but can't tell which files it is.  Try this command instead, which will print the name of the file also:

    find /etc -type f -print -exec grep PATH {} \; > list-2.txt

Small change... the -print option needs to come after the -exec option:
    find /etc -type f -exec grep PATH {} \; -print > list-2.txt

OK. Here is the output.

What are the locations of your v4 perl and your v5.8 perl?

Hi:

Perl 5.8-> /opt/perl_32/bin
perl 4 ->
./opt/perl
./opt/perl/bin/perl

Thanks

You need to make sure /opt/perl_32/bin is in front of opt/perl/bin/perl to use perl 5.8.

for ksh/sh users, check /etc/opt/exp/profile.central to make sure your PATH is defined correct.

put the statements in http:#23595975

FYI, sh/ksh also use /etc/profile, chs/tcsh use /etc/csh.login file.

PATH=/opt/perl_32/bin:$PATH
export PATH

will lead to use perl 5.8 first, but you need to make sure everyone have permission to access to /opt/perl_32/bin.

Thanks, but I already changed he locations you spoke of(/etc/profile and /etc/opt/exp/profile.central )
So it has to be something else...

>>Thanks, but I already changed he locations you spoke of(/etc/profile and /etc/opt/exp/profile.central )

If someone re-defined PATH/path in their .profile/.cshrc, eg,

PATH=/use/bin:/other/bin

export PATH

or other application ENV setting re-defined the PATH, they will NOT use the PATH defined in (/etc/profile and /etc/opt/exp/profile.central !

Both /etc/csh.login (used by csh/tcsh) and /etc/profile (used by sh/ksh) use /etc/PATH to set the path. In /etc/profile, I see that /opt/perl_32/bin is initially set as the first directory in the PATH, but then later on, the contents from /etc/PATH are used to overwrite it.  Does /ect/PATH exist?  If so, make sure /opt/perl_32/bin comes before /opt/perl and /opt/perl/bin.  You can post it here for more help.

Hi Adam314.
Yes, the etc/PATH exists but I already added the /perl_32 location to it...
This is the content:

/opt/perl_32/bin:/usr/bin:/usr/ccs/bin:/usr/contrib/bin:/opt/nettladm/bin:/opt/fc/bin:/opt/fcms/bin:/opt/upgrade/bin:/opt/pd/bin:/usr/bin/X11:/usr/contrib/bin/X11:/opt/hparray/bin:/opt/graphics/common/bin:/opt/gnome/bin:/opt/ignite/bin:/opt/hpnpl//bin

Try logging in as one of the users that uses the old perl by default, and run this at a prompt:
    echo ${PATH}

This gives
/bin:/usr/bin:.:/usr/bin/X11:.:/usr/local/bin:.:/usr/sbin:.:/usr/contrib/bin:/op
t/expert/exp/bin:/opt/netscape6

According to that, neither perl version should be found.  When you are that user, what is the output from this:
    which perl
and this:
    perl -v

and what is the current directory when you run those?

which perl gives this:
/usr/contrib/bin/perl

perl -v gives this:

This is perl, version 4.0

I ran those from my homedir

Why not modify the user's login script as already suggested.

I did...
I did all the changes suggested here, but nothing seems to work...

And what shell is being used?

Also, in the users home dir, post the .cshrc and .profile (or the relavant portions).

Here are the files from the homedir as well as the files they point to....

In csh,  you set environment variables with the setenv command, not with export.  So in your cshrc.central, this line:
    export PATH="/opt/perl_32/bin:${PATH}"
should be:
    setenv PATH "/opt/perl_32/bin:${PATH}"

Thanks a lot.
This is what happens now:
When I do a telnet session and perl -v it gives version 4.
When I type csh and then do a telnet -v it gives v5.8
So does this mean that the "startup-shell" is no csh (i supposed it was because it is the same form then when I type csh - also username@`hostname`)?
If so, where should I adapt the perl version for this shell?

Thanks

    When I type csh and then do a telnet -v it gives v5.8
-> I mean perl -v of course

After logging in, if you type "ps"  (minus the double-quotes), it'll list running processes, which should be only your shell.  That will tell you which shell you are running.


Do you always log in with telnet, or do you ever log in any other way?

Try this, and post all of the output here:
    log in
    ps
    echo ${PATH}
    which perl
    perl -v
    csh
    echo ${PATH}
    which perl
    perl -v

Hi,

99% of the time I log in using telnet, but sometimes I login in the CDE....

You need to find out what  is your default login SHELL, after you login type in:

echo $SHELL

then have a look at my comment in http:#23595975 to modify your login script for your default login shell.

If you maunually swith shell in command line, you need to "source" your" login script for the new shell,

eg:

your default login shell is ksh, youtype in "csh" to change to csh, you need to do:

source /path-to/.cshrc

or

if your default login shell is csh, you type in "ksh" to use ksh, you need to do:

. /path-to/.profile     (a DOT following by a SPACE)

assume you have setup the PATH/path correctly in the .profile/.cshrc file.

These lines here:
    BD88@HPse_1:/home/BD88% which perl
    /opt/perl_32/bin/perl
    BD88@HPse_1:/home/BD88% perl -v
    This is perl, version 4.0
Make it appear that the /opt/perl_32/bin/perl is perl v 4.0.

But then these lines:
    BD88@HPse_1:/home/BD88% which perl
    /opt/perl_32/bin/perl
    BD88@HPse_1:/home/BD88% perl -v
    This is perl, v5.8.8 built for PA-RISC1.1-thread-multi
Make it appear that /opt/perl_32/bin/perl is perl v 5.8.8.

A few more things to try... do this using the same user and log-in method as before
    log in
    type:
        /opt/perl_32/bin/perl -v
    type:
        perl -e 'print "$^X\n"'

Also, after logging in, type this:
    alias
It might be there is an alias for perl defined causing the behavior.

       /opt/perl_32/bin/perl -v
gives 5.8
 perl -e 'print "$^X\n"'
gives the text "perl/n"
AFTER I start the csh, it just gives the text "perl"
There is no alias defined regarding to perl.

You can do what I do with old Perls on HPUX and rename the binary.  We have a load of 11iv1 machines which have Perl 5.0 installed.  Our app requires Perl 5.8.8, so to avoid the 5.0 one being used, I rename /usr/bin/perl to /usr/bin/perl5_0.  Nothing seems to require this, as long as there is another Perl available, so it works for us.  YMMV.
