Install perl to /usr/local/bin

  • 772

Is it possible to install perl to /usr/local/bin without full sudo permissions namely only sudo apt install ... being allowed.

I have a DVD with a software, using /usr/local/bin/perl in shebang, variables, paths etc. Yet on my machine perl is in /usr/bin .

I am not admin on my machine. I asked IT to to create copy or link to perl file ( sudo ln -s /usr/bin/perl /usr/local/bin/perl) yet it might take time. Is there other way? I have no admin/sudo permissions but allowed to install soft using standard package manager apt .

Perl 5.22 but close version would probably do, Ubuntu 16.04

Update 1. As recommended in answers I run a replace on a copy of the soft. I though installed and used designated text replacement command rpl. Still curios are there other solution e.g. is it possible to compile perl into .deb package that I can installs into desired folder with apt install.

Update 2. IT helpdesk created links for me, can run scripts now.

  1. You can build Perl from source, then placing them to /usr/local/bin.

    1. Download perl tarball file from their website, unpack it.

      wget https://www.cpan.org/src/5.0/perl-5.22.0.tar.gz
tar -xvzf perl-5.22.0.tar.gz
cd perl-5.22.0/

    2. Proceed to installation through make.

      ./Configure -des -Dprefix=/usr/local
make
make test
sudo make install

    This will install Perl version 5.22.0 to directory /usr/local/bin, which you can call the executable as /usr/local/bin/perl.

    :~$ /usr/local/bin/perl --version

This is perl 5, version 22, subversion 0 (v5.22.0) built for x86_64-linux

    Although the most logical way would be replacing the shebang line to exactly /usr/bin/perl, you can do so by.

    find /path/to/script -name '*.pl' | xargs perl -pi -e 's{^#!/usr/local/bin/perl}{#!/usr/bin/perl}'

    Will change #!/usr/local/bin/perl → #!/usr/bin/perl.
