Need Help??

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
[download]

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	[reply]
