我需要删除系统头文件重复而不影响其余代码
我试过
sub uniq {
my %seen = ();
my @r = ();
foreach my $a (@_) {
unless ($seen{$a}) {
push @r, $a;
$seen{$a} = 1;
}
}
return @r;
}
@lines_temp = uniq(@lines_temp);
但它删除了所有类型的重复,包括'(','{'和空格
我只需删除重复的系统文件

sub uniq {
my %seen;
my @r;
for my $a (@_) {
my ($m) = $a =~ /#include\s+<(.+?)>/;
push @r, $a if !$m or !$seen{$m}++;
}
return @r;
}
@lines_temp = uniq(@lines_temp);
或
sub uniq {
my %seen;
return grep {
my ($m) =~ /#include\s+<(.+?)>/;
!$m or !$seen{$m}++;
} @_;
}
@lines_temp = uniq(@lines_temp);
或oneliner,
perl -ne '($m) = /#include\s+<(.+?)>/; print if !$m or !$s{$m}++' file
