The file name? It's in $ARGV:
$ARGV contains the name of the current file when reading from <>.
I often use this in a variation on grep:
perl -ne 'print "$ARGV:$.:$_" if /something/ or /other/' *.c
which is a bit like grep -n but I can use Perl (specifically useful
also for grepping through things such as tarballs by specifying a max
line length and converting non-printable characters to question marks
or something).
Cheers,
Philip
