Or Tie::File, or `print [<FILE>]->[-1];` [download] []s, HTH, Massa (κς,πμ,πλ)	[reply] [d/l]

`print [<FILE>]->[-1];` If you mention such things you should also add that it reads the entire file into memory. That might be a bit overkill... Another thing that came to my mind, but is restricted to unixy systems: my $line = `tail -n1 $file`; [download]	[reply] [d/l] [select]

In addition to the more important observation that moritz made, I can never understand why so often do people seem to feel the need to reference only to dereference like that; i.e. if we assume we do want to slurp the file all at once, then `print +(<$file>)[-1]; # would do!` [download] `--` ~~If you can't understand the incipit, then please check the IPB Campaign.~~	[reply] [d/l] [select]
