Re^2: Writing unix-style filters

chomp( @files = @ARGV ? grep { -f $_ } @ARGV : <> );

This chomps after you do the file test, with the newline not yet removed. So, it will just produce an empty array, when reading the file list from the input, because -f $_ will always return false.

No; actually, it will not, because the `-f` test operator here is not being applied to the strings which are returned from the `<>`. Perhaps it should be; in which case you'd have a very good point. `chomp( @files = @ARGV ? @ARGV : <> ); @files = grep { -f $_ } @files;` [download] A word spoken in Mind will reach its own level, in the objective world, by its own weight	[reply] [d/l] [select]
