Error create control file in UNIX
UNIX gurus:

Following is what I am trying to do:

I need to create a control file for another file that I am creating. The information needed in the control file is the date in YYYYMMDD format and then the number of records in the other file right justified and lpadded with spaces of 20.

So say I have a file a.dat and it has 200 records.
I need to create a control file a.ctl having the following data.

20060605 200

I can only use UNIX commands as I am not allowed to use any scripts. I know date +'%Y%m%d' will give me the date in YYYYMMDD format and wc -l <filename> would give me record count but how would I go about piping the output of the above to one control file?

deb-old

deb-old(5)							    dpkg suite								deb-old(5)

NAME

       deb-old - old style Debian binary package format

SYNOPSIS

       filename.deb

DESCRIPTION

       The  .deb  format  is the Debian binary package file format. This manual page describes the old format, used before Debian 0.93. Please see
       deb(5) for details of the new format.

FORMAT

       The file is two lines of format information as ASCII text, followed by two concatenated gzipped ustar files.

       The first line is the format version number padded to 8 digits, and is 0.939000 for all old-format archives.

       The second line is a decimal string (without leading zeroes) giving the length of the first gzipped tarfile.

       Each of these lines is terminated with a single newline character.

       The first tarfile contains the control information, as a series of ordinary files. The file control must be present,  as  it  contains  the
       core control information.

       In  some  very  old  archives,  the  files  in  the  control  tarfile  may optionally be in a DEBIAN subdirectory. In that case, the DEBIAN
       subdirectory will be in the control tarfile too, and the control tarfile will have only files in that  directory.  Optionally  the  control
       tarfile may contain an entry for '.', that is, the current directory.

       The second gzipped tarfile is the filesystem archive, containing pathnames relative to the root directory of the system to be installed on.
       The pathnames do not have leading slashes.

       deb(5), dpkg-deb(1), deb-control(5).
