If file size is a concern, just keep the recent lines in
an array instead of slurping up everything. I just
threw this thing together but it seems to do the trick:
use strict;
my $fileglob = shift || '*.pl';
my $pattern = shift || 'hello';
my $keeplines = shift || 3;
for my $file (<${fileglob}>) {
unless(open(IN, $file)) { warn "Can't read from $file: $!"; next; }
my @lines;
while(<IN>) {
push @lines, $_;
shift @lines if(@lines > $keeplines);
if(/$pattern/i) {
print "--- From $file:---\n@lines\n"
}
}
}
