as00060 has asked for the wisdom of the Perl Monks concerning the following question:

Hello All,

First, I find it very surprising that after the installation of Fedora OS, I couldn't find Perl on it, when I fire the command "perl -v", it returns " command not found". So, really not sure if I have done any mistake, as the OS installation was successful with no errors, I have given 22 GB disk space to the OS in my Oracle VirtualBox.

Second, I downloaded the ActivePerl-5.20.2.2002-x86_64-linux-glibc-2.15-299195.tar from perl.org. extracted it, and fired the command

# tar -xvf ActivePerl-5.20.2.2002-x86_64-linux-glibc-2.15-299195.tar

[download]

It went fine, then I fired the command

# ./install.sh

[download]

There was some interactive questions including "Enter top level directory for install? [/opt/ActivePerl-5.20]"

Since I wanted to install/configure the Perl under following path

/opt/perl/ActivePerl-5.20

[download]

So, I have given the path, and hit enter, it progressed without any flaws, and installation was success, and I got the following directories.files in the above path.

[root@fedora ActivePerl-5.20]# ll
total 24
drwxr-xr-x.   2 root root 4096 Jul 19 14:44 bin
drwxrwxr-x.   2 root root 4096 Sep 20 02:13 etc
drwxr-xr-x.   8 root root 4096 Sep 20 02:13 html
drwxr-xr-x. 101 root root 4096 Jul 19 14:44 lib
drwxr-xr-x.   4 root root 4096 Jul 19 12:45 man
drwxr-xr-x.   3 root root 4096 Jul 19 12:44 site

[download]

I then went to .bash_profile, and set the env variable as 

PATH=/opt/perl/ActivePerl-5.20

[download]

However,I could see the following path already mentioned in the above path 

PATH=$PATH:$HOME/bin

[download]

I had commented the path before I put mine .

Size to /opt is 4 GB.

    So, where exactly is your problem?

    Does the following command work?

    /opt/perl/ActivePerl-5.20/bin/perl -v

    [download]

    Most likely, you want to add the following line to your ~/.bashrc:

    export PATH=$PATH:/opt/perl/ActivePerl-5.20/bin

    [download]

    YOu might also want to investigate how to install the vendor-packaged Perl for your OS. Maybe yum perl installs the vendor packaged Perl package.

      Q) Does the following command work? /opt/perl/ActivePerl-5.20/bin/perl -v >> yes , it does. Q)Most likely, you want to add the following line to your ~/.bashrc: export PATH=$PATH:/opt/perl/ActivePerl-5.20/bin >> As I have mentioned earlier, I have already set the path, may not be with your suggested method though. My concern is that, in the given scenario, if I have to execute any perl program, I will have to mention entire path of the perl, I just want to avoid this limitation. e.g. if I execute "perl <xyz.pl>" from the location of the program "perl -v" from any location neither of them would work, for both the scenario, I will have to mention full path to perl,whereas this shouldn't be happening. If this issue could be resolved, I am good to go.

        I have already set the path

        If you still need to invoke perl by specifying the entire path, then you haven't set the path correctly.
        (Once it's set correctly you won't need to specify the full path and you'll be able to invoke perl as simply perl)

        Cheers,
        Rob

    Fedora has perl & lots of perl modules in it's repository, just install it with your favourite package manager.

    BTW -- if you want to install it from the command line, fedora 22 has replaced yum with dnf.

    Hello as00060,

    I stopped using Fedora more than 10 years ago, but did you look in '/usr/local/bin' directory? If you see links in that directory to other programs, you should be able to add the following: 

      ln -s /opt/perl/ActivePerl-5.20/bin/perl myperl   # use whatever nam
+e you want

    [download]
    Then when you type 'myperl' on the command line it should use the Active Perl command you installed.

    That should work no matter what account you're 'login'ed under.

    Good Luck...Ed

      Hi, I was missing on the soft link part. @Ed, your suggestion worked for me thanks a ton. We can now conclude the discussion. Thanks to all for your time. Regards, Amitesh

    And it would help readers of your post to break up that mass of words into paragraphs and blocks of code.
