文件列表：

sysbench-size-256M-mode-rndrd-threads-4

我想按模式(rndrd,rndwr等)对它们进行排序,然后编号：

sysbench-size-256M-mode-rndrd-threads-1
sysbench-size-256M-mode-rndrd-threads-4
sysbench-size-256M-mode-rndrd-threads-8
sysbench-size-256M-mode-rndrd-threads-16
sysbench-size-256M-mode-rndrw-threads-1
sysbench-size-256M-mode-rndrw-threads-4
sysbench-size-256M-mode-rndrw-threads-8
sysbench-size-256M-mode-rndrw-threads-16
....

我尝试了以下循环,但它按数字排序,但我需要像1,4,8,16这样的序列：

$for f in $(ls -1A); do echo $f; done | sort -t '-' -k 7n

编辑：

请注意数字排序(-n)按数字(1,1,4 …)排序,16,4这样的序列,16 …

解决方法

for循环是完全没有必要的,因为在管道输出时ls的-1参数.这产生了

ls -A | sort -t- -k 5,5 -k 7,7n

其中第一个键在第5列开始和结束,第二个键在第7列开始和结束,并且是数字.
