Code:
#!/usr/bin/ksh
# test:
# touch file_00000001.cvs file_00000002.cvs

# last file*.cvs file
last=$( ls -1 file*.cvs 2>/dev/null  | tail -1 )

# remove all a-z . and _ from filename
last=${last//[a-z_.]}

# if empty = no files => 1st file
[ "$last" = "" ] && last=0 # 1st file

((new=last+1))
newname=$(printf "file_%0.8d.cvs" $new)
do_something > $newname

Or make cnt file and use it
Code:
[ ! -f last.txt ] && echo "0" > last.txt # 1st id
read last < last.txt

((new=last+1))
newname=$(printf "file_%0.8d.cvs" $new)
# save id
echo "$new" > last.txt
# 
do_something > $newname

cvs-debrelease

CVS-DEBC(1)						      General Commands Manual						       CVS-DEBC(1)

NAME

       cvs-debrelease - upload a cvs-buildpackage/cvs-debuild generated package

SYNOPSIS

       cvs-debrelease [cvs-debrelease options] [--dopts [dupload/dput options]]

DESCRIPTION

       cvs-debrelease  is run from the CVS working directory after cvs-buildpackage or cvs-debuild.  It uses the cvs-buildpackage system to locate
       the .changes file generated in that run.  It then uploads the package using debrelease(1), which in turn  calls	either	dupload  or  dput.
       Note  that  the	--dopts  option  must  be specified to distinguish the cvs-debrelease options from the dupload or dput options.  Also, the
       devscripts configuration files will be read, as described in the debrelease(1) manpage.

       Note that unlike cvs-buildpackage, the only way to specify the source package name is with the -P option; you cannot simply have it as  the
       last command-line parameter.

OPTIONS

       All  current  cvs-buildpackage options are silently accepted; however, only the ones listed below have any effect.  For more details on all
       of them, see the cvs-buildpackage(1) manpage.  All debrelease options (as listed below) are also accepted.

       --dupload, --dput
	      This specifies which uploader program to use; the default is dupload.

       -adebian-architecture, -tGNU-system-type
	      See dpkg-architecture(1) for a description of these options.  They affect the search for the .changes file.  They  are  provided	to
	      mimic the behaviour of dpkg-buildpackage when determining the name of the .changes file.

       -Mmodule
	      The name of the CVS module.

       -Ppackage
	      The name of the package.

       -Vversion
	      The version number of the package.

       -Ttag  The CVS tag to use for exporting sources.

       -Rroot directory
	      Root of the original sources archive.

       -Wwork directory
	      The full path name for the cvs-buildpackage working directory.

       -xprefix
	      This option provides the CVS default module prefix.

       --no-conf, --noconf
	      Do not read any configuration files.  This can only be used as the first option given on the command-line.

       --help, --version
	      Show help message and version information respectively.
