in reply to One to one file output idiom

Another suggestion of mine form the CB discussion:
perl -pwe 'open STDOUT, ">", "$ARGV.txt" if $last ne $ARGV; s/.*/\U$&/ +; $last = $ARGV' *.obj

Update: Using eof is a bit cleaner, but it still triggers at a wrong time, so it couldn't be used directly:

perl -pwe 'open STDOUT, ">", "$ARGV.txt" unless $e; $e = ! eof; s/.*/\ +U$&/' *.obj

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    maybe try $. to catch the first line per file, like
    C:\tmp\files>perl -nE"say qq($.--$ARGV) if $.==1; $.=0 if eof " a b c 1--a 1--b 1--c

    Unfortunately I need to reset $. at the end of each file, which is kind of hacky! :/

      Closing ARGV before it gets opened again would be the non hacky thing way to do it since it's shown in the doc, although it's a bit longer.

      Edit: choroba pointed out it was shown in the doc for eof not open
