perl_reverse_sort_scalar
学习perl的reverse,sort,scalar,记录一下。
- [root@OTRS perl]# more reverse_sort_scalar.pl
- #!/usr/bin/perl -w
- use strict;
- #reverse
- my @array_reverse = 1..3;
- my @array_ed = reverse(@array_reverse);
- print "数组的值为1 2 3,reverse反转数组的值为: ","@array_ed\n";
- #sort
- my @array_sort = qw/c b a/;
- my @sorted = sort@array_sort;
- print "数组的值为c b a,sort排序后为: ","@sorted\n";
- #scalar强制指定标量上下文。
- my @array_scalar = qw/a b c/;
- print "数组的值为abc,scalar指出数组的个数为:",scalar@array_scalar,"\n";
- [root@OTRS perl]# perl reverse_sort_scalar.pl
- 数组的值为1 2 3,reverse反转数组的值为: 3 2 1
- 数组的值为c b a,sort排序后为: a b c
- 数组的值为abc,scalar指出数组的个数为:3
