I was thinking that you put "f19" as your input file name, but that doesn't appear to be the case as can be deduced from your post above. "f19" was just a dummy file that I had created on my system to test the script.

Good that you mentioned you are on Windows. Quoting works differently on Windows than on *nix.

The Windows equivalent of my earlier post would be this -

Code:
C:\> type f19
C:\> perl -lne "if ($.<=4) {push @x,$_} else {$x[($.-1)%4] .= \" \".(split)[2]} END {print for @x}" f19

And you'd want to substitute f19 by your input file name.

Note that the main script is enclosed within double quotes, and the inner double quotes are escaped. I don't have Windows anywhere near me right now, so the commands are untested.

HTH,

DH_PERL(1)							     Debhelper								DH_PERL(1)

NAME
dh_perl - calculates Perl dependencies and cleans up after MakeMaker SYNOPSIS
dh_perl [debhelperoptions] [-d] [librarydirs...] DESCRIPTION
dh_perl is a debhelper program that is responsible for generating the ${perl:Depends} substitutions and adding them to substvars files. The program will look at Perl scripts and modules in your package, and will use this information to generate a dependency on perl or perlapi. The dependency will be substituted into your package's control file wherever you place the token ${perl:Depends}. dh_perl also cleans up empty directories that MakeMaker can generate when installing Perl modules. OPTIONS
-d In some specific cases you may want to depend on perl-base rather than the full perl package. If so, you can pass the -d option to make dh_perl generate a dependency on the correct base package. This is only necessary for some packages that are included in the base system. Note that this flag may cause no dependency on perl-base to be generated at all. perl-base is Essential, so its dependency can be left out, unless a versioned dependency is needed. -V By default, scripts and architecture independent modules don't depend on any specific version of perl. The -V option causes the current version of the perl (or perl-base with -d) package to be specified. library dirs If your package installs Perl modules in non-standard directories, you can make dh_perl check those directories by passing their names on the command line. It will only check the vendorlib and vendorarch directories by default. CONFORMS TO
