I want to execute following perl-one-liner on a set of files (tmp_*) in a directory....

% perl -e ' while (<>) { if (/: /) {  $c += (split /: /)[0]; }  } prin
+t "SUM.$ARGV =$c\n"' tmp_*

[download]

or

%perl -e ' while (<>) { if (/: /) {  $c += (split /: /)[0]; }  } print
+ "SUM.$ARGV =$c\n"' | xargs cat tmp_filelist
[download]

so on..... Nothing seems to work...it just does for one file and exits.... Help
