I have a file that has four values on each line and I'd like to give each column a variable name and then use those values in each step of a loop.

perl-after-upgrade
PERL-AFTER-UPGRADE(1) User Contributed Perl Documentation PERL-AFTER-UPGRADE(1)NAME
perl-after-upgrade -- fixup FreeBSD packages that depend on perl
SYNOPSIS
perl-after-upgrade
perl-after-upgrade -f
perl-after-upgrade -v
DESCRIPTION
The standard procedure after a perl port (either lang/perl5.6 or lang/perl5.8) upgrade is to basically reinstall all other packages that
depend on perl. This is always a painful exercise. The perl-after-upgrade utility makes this process mostly unnecessary.
The tool goes through the list of installed packages, looks for those that depend on perl, moves files around, modifies shebang lines in
those scripts in which it is necessary to do so, tries its best to adjust dynamically linked binaries that link with libperl.so in the old
path, and updates the package database.
After installation of the new perl is complete, either by hand from the ports collection, or from a package, or via portupgrade, do the
following:
o go root;
o run perl-after-upgrade utility.
Do not specify any arguments at first, so it does nothing destructive. Pay attention to the produced output and especially to
errorlist at the end, if any;
o run the utility again, with -f command line option.
This will actually do the work. Again, pay attention to the output produced;
o fix any reported errors;
o reinstall required packages:
The utility will tell you what packages that depend on perl it could not handle. It will also tell you why it happened (for example,
they were compiled against a binary incompatible perl). If you want such packages to remain operational, you will have to reinstall
then by hand or via portupgrade.
o review the files left in the older perl installation.
This is typically /usr/local/lib/perl5/site_perl/5.X.Y/. There should be very little, if any, files in that directory and its subdi-
rectories, excepting a number of .ph files;
o check that things work as they should;
o remove backup files from the package database.
Those will be /var/db/pkg/*/+CONTENTS.bak;
o that's all.
