【问题描述】:
这是使用 find 查找文件并显示每个文件中的行数的方法
$ find ./ -type f -name "data*.csv" -exec wc -l {} +
380723 ./data_2016-07-07-10-41-13.csv
369869 ./data_2016-07-11-10-42-01.csv
363941 ./data_2016-07-08-10-41-50.csv
378981 ./data_2016-07-12-10-41-28.csv
1493514 total
如何按文件名对结果进行排序?以下是我的尝试,但它不起作用。
$ find ./ -type f -name "data*.csv" -exec wc -l {} + | sort
1493514 total
363941 ./data_2016-07-08-10-41-50.csv
369869 ./data_2016-07-11-10-42-01.csv
378981 ./data_2016-07-12-10-41-28.csv
380723 ./data_2016-07-07-10-41-13.csv
$ find ./ -type f -name "data*.csv" | sort -exec wc -l {} +
sort: invalid option -- 'e'
Try `sort --help' for more information.
$ find ./ -type f -name "data*.csv" -exec sort | wc -l {} +
find: wc: {}missing argument to `-exec'
: No such file or directory
wc: +: No such file or directory
0 total
$
谁能提供解决方案并纠正我以便我更好地理解它?

来自man sort
-k, --key=POS1[,POS2]
start a key at POS1 (origin 1), end it at POS2 (default end of line). See POS syntax below
POS is F[.C][OPTS], where F is the field number and C the character position in the field; both are origin 1. If neither -t nor -b is in effect, characters in a field are counted from the begin‐
ning of the preceding whitespace. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key.
