Question

Perl将一个值写入文件

现在又一个值处理完毕之后，如$a，想把他写入文件outfile，请问应该怎么用perl语言写出来，就像linux里面的 $ <command> > outfile，这种一样的意思

Answer 1

Perl将值写入文件，参考实例如下：
1、open( my $fh, '>', 'fruit.out' ) or die $!;
print $fh $_ for @output;
2、open (OUTFILE,">>./outfile");

print OUTFILE "$a";
close(OUTFILE);
数组写入如下：
#从头开始写
open(FILE,">fruit.txt");
#文件结尾追加
open(FILE,">>fruit.txt");
print FILE "@arr";

Answer 2

open (OUTFILE,">>./outfile");
print OUTFILE "$a";
close(OUTFILE);
