Answer by Jim for Install perl to /usr/local/bin

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.
