perlquestion abhay180 I want to execute following perl-one-liner on a set of files (tmp_*) in a directory.... <code> % perl -e ' while (<>) { if (/: /) { $c += (split /: /)[0]; } } print "SUM.$ARGV =$c\n"' tmp_* </code> or <code> %perl -e ' while (<>) { if (/: /) { $c += (split /: /)[0]; } } print "SUM.$ARGV =$c\n"' | xargs cat tmp_filelist </code> so on..... Nothing seems to work...it just does for one file and exits.... Help
