输出 ls -l size 字段，其中数字以千为单位分组？

输出 ls -l size 字段，其中数字以千为单位分组？

是否可以使 ls -l 输出以千为单位的数字大小字段？如果是这样，怎么办？

例如：

$ ls -l
-rw-rw---- 1 dahl dahl 43,210,052 2012-01-01 21:52 test.py

（注意尺寸中的逗号）。

也许通过修改我正在使用的语言环境中的 LC_NUMERIC 设置（en_US.utf8）？

我使用的是 Kubuntu 12.04 LTS。

块大小 - GNU Coreutils说

前面带有 ' 的块大小规范会导致输出大小以千位分隔符显示。 （请注意，仅指定块大小是不够的）。

所以根据你想要的，你可以尝试

BLOCK_SIZE="'1" ls -l
BLOCK_SIZE="'1kB" ls -l

或者

ls -l --block-size="'1"
ls -l --block-size="'1kB"

你可以使用它使其永久

export BLOCK_SIZE="'1"
export BLOCK_SIZE="'1kB"

或者

alias ls="ls --block-size=\"'1\""
alias ls="ls --block-size=\"'1kB\""

使用 ast-open 的ls（也是作为 ast-open 的一部分构建的 ifls的内置函数ksh93）：

$ ls -rSZ "%(mode)s %3(nlink)u %-8(uid)s %-8(gid)s %8(device:case::%'(size)u:*:%(device)s)s %(mtime)s %(name)s%(linkop:case:?*: %(linkop)s %(linkpath)s)s"
[...]

-rwxrwxr-x   2 chazelas chazelas 4,515,954 Apr 27  2016 ksh
-rwxrwxr-x   2 chazelas chazelas 4,515,954 Apr 27  2016 bash
-rwxrwxr-x   1 chazelas chazelas 4,542,177 Apr 27  2016 shcomp
-rwxrwxr-x   1 chazelas chazelas 6,830,418 Apr 27  2016 tksh

这是通常使用的格式，ls -l但已%(size)u更改为%'(size)u显示千位分隔符。

更清晰：

LONG_FORMAT_WITH_THOUSAND_SEP="\
%(mode)s \
%3(nlink)u \
%-8(uid)s \
%-8(gid)s \
%8(device:case::%'(size)u:*:%(device)s)s \
%(mtime)s \
%(name)s\
%(linkop:case:?*: %(linkop)s %(linkpath)s)s"

ls -rSZ "$LONG_FORMAT_WITH_THOUSAND_SEP"

从手册页

--block-size=SIZE
          scale sizes by SIZE before printing them.  E.g., `--block-size=M'   
          prints sizes in units of 1,048,576 bytes.  See SIZE format below.

_这是 ls 的手册页，记住 man 是你最好的朋友，在你的终端中输入“man man”来了解它有多有用。
