But if you are on Win32, you instead could use: 

perl -i.one -le "BEGIN{@ARGV= glob(@ARGV)} chomp( my @cinfo= <> ); $ci
+nfo[1]= 0; print @cinfo" *.txt
perl -i.one -e "BEGIN{@ARGV= glob(@ARGV)} my @cinfo= <>; $cinfo[1]= 0.
+$/; print @cinfo" *.txt
perl -i.one -nle "BEGIN{@ARGV= glob(@ARGV)} print 2==$. ? 0 : $_" *.tx
+t
perl -i.one -ple "BEGIN{@ARGV= glob(@ARGV)} $_= 0 if 2==$." *.txt
perl -i.one -pe "BEGIN{@ARGV= glob(@ARGV)} $_= 0.$/ if 2==$." *.txt

But there are lots of other ways you could do it as well.
