制作“ ls”命令排序“ a”;在“ B”之前(vs a-> b-> A-> B) [英] Making the "ls" command sort "a" before "B" (vs a->b->A->B)
问题描述
我试图找到一种以不区分大小写的方式打印ls命令的结果的方法。
I am trying to find a way to have the results of an ls command be printed in a case insensitive manner.
当前执行ls命令会导致:
currently an ls command results in:
Apple
Boy
Chart
Dock
apples
boys
charts
docks
我想要的是什么
Apple
apples
Boy
boys
Chart
charts
Dock
docks
可能吗?
推荐答案
ls
(至少在使用GNU coreutils版本的情况下; ls --version
进行检查)会根据当前语言环境对文件名进行排序。
ls
(at least if you're using the GNU coreutils version; ls --version
to check that) sorts file names according to the current locale.
可用的语言环境集因系统而异(列表中为 locale -a
),但在我的系统上为:
The set of available locales varies from system to system (locale -a
for a list), but on my system this:
LC_COLLATE=en_US.utf8 ls
以 b
a 和 A
的名称进行排序>和 B
-尽管可能与您要查找的顺序不完全。
sorts names with a
and A
before b
and B
-- though it might not be exactly in the order you're looking for.
这有效即使 ls
在多列中列出文件,使用 sort -f
也很难做到。
This works even when ls
lists files in multiple columns, something that's difficult to do with sort -f
.
(我专门将 $ LC_COLLATE
设置为 C
,以便对语言环境敏感排序以ASCII顺序完成。)
(I have $LC_COLLATE
set to C
specifically so that locale-sensitive sorting is done in ASCII order.)
