一点awk就行了?

awk '{s+=$1} END {print s}' mydatafile

注意:如果要添加超过2^31(2147483647)的值，某些版本的awk会有一些奇怪的行为。查看评论了解更多背景信息。一个建议是使用printf而不是print:

awk '{s+=$1} END {printf "%.0f", s}' mydatafile

c++(简体):

echo {1..10} | scc 'WRL n+=$0; n'

SCC是shell提示符下的c++代码段求值器

给红宝石爱好者

ruby -e "puts ARGF.map(&:to_i).inject(&:+)" numbers.txt

更新的基准

所以我合成了随机分布的100mn个整数

之间的

0^0 - 1 

and

8^8 - 1

代码生成器

mawk2 '
BEGIN {
     __=_=((_+=_^=_<_)+(__=_*_*_))^(___=__)
     srand()
     ___^=___
     do  { 
           print int(rand()*___) 
  
     } while(--_)  }' | pvE9 > test_large_int_100mil_001.txt

     out9:  795MiB 0:00:11 [69.0MiB/s] [69.0MiB/s] [ <=> ]

  f='test_large_int_100mil_001.txt'
  wc5 < "${f}"

    rows = 100000000. | UTF8 chars = 833771780. | bytes = 833771780.

最后一位的奇/偶分布

AWK -最快的，有很大的优势(可能C更快，我不知道)

DC

- ( had to kill it after no response in minutes)

$ cat n
2
4
2
7
8
9

$ perl -MList::Util -le 'print List::Util::sum(<>)' < n
32

或者，你可以在命令行输入数字:

$ perl -MList::Util -le 'print List::Util::sum(<>)'
1
3
5
^D
9

但是，这种方法会占用文件，因此不适合用于大文件。请参阅j_random_hacker的答案，以避免吮吸。

使用env变量tmp

tmp=awk -v tmp="$tmp" '{print $tmp" "$1}' <filename>|echo $tmp|sed "s/ /+/g"|bc

tmp=cat <filename>|awk -v tmp="$tmp" '{print $tmp" "$1}'|echo $tmp|sed "s/ /+/g"|bc

谢谢。
