Can someone offer a solution and correct me so I understand it better? 有人可以提供解决方案并纠正我,以便我更好地理解吗?
from man sort
从
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.
Ismail's suggestion of using sort -k
is correct. Ismail关于使用
sort -k
的建议是正确的。 However, I'm often too lazy to learn (or relearn) how -k
works, so here's a cheap solution: 但是,我经常懒得学习(或重新学习)
-k
工作方式,因此这里有一个便宜的解决方案:
find . -name 'data*.csv' -print0 | sort -z | xargs -0 wc -l
Edit: after some experimentation, I did figure out how -k
works: 编辑:经过一些试验,我确实弄清楚了
-k
工作原理:
find . -name 'data*.csv' -exec wc -l {} + | sort -k 2
