[英]UNIX: Sort files by number/version without 0 padding
Ultimately, I wanted to set the latest version as an environment variable, so supplementing the selected answer (which provided me the correct sorting): 最终,我想将最新版本设置为环境变量,因此补充所选答案(这为我提供了正确的排序):
export LATEST_VERSION=$(printf '%s\n' * | sort -rV | head -1)
I have a directory with the following directory names: 我有一个目录,其中包含以下目录名称:
ls -1r .
2.0
1.8
16.1
16.0
15.5
15.0
14.5
14.1
14.0
1.3
1.2
1.1.5
1.1.3
1.1.2
I would like to sort them to get the latest release version: 我想对它们进行排序以获得最新版本:
ls -1r . | head -1
16.1
So the underlying order should look like this: 因此基础订单应如下所示:
16.1
16.0
15.5
15.0
14.5
14.1
14.0
2.0
1.8
1.3
1.2
1.1.5
1.1.3
1.1.2
Any help would be greatly appreciated. 任何帮助将不胜感激。 Simpler the better, but I'm open to any solution. 越简单越好,但我对任何解决方案都持开放态度。 Thanks! 谢谢!
Modern GNU sort offers a -V
flag for sorting according to version number rules: 现代GNU排序提供-V
标志,用于根据版本号规则进行排序:
$ printf '%s\n' * | sort -rV
16.1
16.0
15.5
15.0
14.5
14.1
14.0
2.0
1.8
1.3
1.2
1.1.5
1.1.3
1.1.2
Note that the above does not use ls
. 注意,上面没有使用ls
。 As a general rule, you shouldn't parse the output of ls(1) . 作为一般规则, 您不应解析ls(1)的输出 。
From man sort
: 从man sort
:
-V, --version-sort -V, - version-sort
natural sort of (version) numbers within text 文本中的自然类型(版本)数字
The above is from the GNU man page. 以上内容来自GNU手册页。
FreeBSD's sort also supports -V
. FreeBSD的排序也支持-V
。
Apple's sort is a GNU sort from the year 2005 which predates support for the -V
option. Apple的排序是从2005年开始的GNU排序,早于对-V
选项的支持。 A work-around can be found here . 可以在这里找到解决方法。 (Hat tips: l'L'l, mklement0) (帽子提示:l'L'l,mklement0)
FWIW, I'm in Mac OS right now, and haven't booted over to linux to test. FWIW,我现在在Mac OS,并没有启动到linux进行测试。 But, it looks like sort with the numeric option has the smarts to do it: 但是,看起来像使用数字选项的排序有聪明才能做到:
But, I have a directory with your subdirectories in it, and ls sorts it badly: 但是,我有一个包含子目录的目录,并且ls严重排序:
/Users/thedave/tmp $ ls -1r
2.0
16.1.12
16.1
16.0
15.5
15.0
14.5
14.1
14.0
1.8
1.3
1.2
1.1.5
1.1.3
1.1.2
1.1
1.0.1
1.0
sort(1) accepts '-n' for numeric and '-r' for reverse: sort(1)接受'-n'表示数字,' - r'表示反向:
/Users/thedave/tmp $ ls | sort -rn
16.1.12
16.1
16.0
15.5
15.0
14.5
14.1
