I am trying to take first 3 columns in a file which matches the word "abc", but i am getting the below error,
<error>
Global symbol "@F" requires explicit package name at ./new.pl
</error>

whereas when i give the below,grep abc /home/test/file.txt|perl -lane 'print \"$F[0] $F[1] $F[2]\" in unix prompt i am getting the result. When i use inside the perl script it fails. When i remove "use strict" it returns nothing.Please help me out


Code:
#!/usr/bin/perl
use strict;
use warnings;

dh_installdebconf

DH_INSTALLDEBCONF(1)                                                 Debhelper                                                DH_INSTALLDEBCONF(1)

NAME

       dh_installdebconf - install files used by debconf in package build directories

SYNOPSIS

       dh_installdebconf [debhelperoptions] [-n] [--params]

DESCRIPTION

       dh_installdebconf is a debhelper program that is responsible for installing files used by debconf into package build directories.

       It also automatically generates the postrm commands needed to interface with debconf. The commands are added to the maintainer scripts by
       dh_installdeb. See dh_installdeb(1) for an explanation of how that works.

       Note that if you use debconf, your package probably needs to depend on it (it will be added to ${misc:Depends} by this program).

       Note that for your config script to be called by dpkg, your postinst needs to source debconf's confmodule. dh_installdebconf does not
       install this statement into the postinst automatically as it is too hard to do it right.

FILES

       debian/package.config
           This is the debconf config script, and is installed into the DEBIAN directory in the package build directory.

           Inside the script, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.

       debian/package.templates
           This is the debconf templates file, and is installed into the DEBIAN directory in the package build directory.

       debian/po/
           If this directory is present, this program will automatically use po2debconf(1) to generate merged templates files that include the
           translations from there.

           For this to work, your package should build-depend on po-debconf.

OPTIONS

       -n, --no-scripts
           Do not modify postrm script.

       -- params
           Pass the params to po2debconf.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
