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,

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
