脚本文件名以前导数字来确定执行顺序的用例

我正在寻找文档或用例，其中 Linux 中有一个包含 shell 脚本的目录，其中每个文件名都以数字开头，并且文件按特定顺序运行。这个约定叫什么？在哪里使用？

例如：

0001-motd.sh
0002-proxy.sh
0300-ssh.sh

我知道我以前见过这个，只是不确定它在哪里或叫什么。

听起来你指的是run-parts

NAME
       run-parts - run scripts or programs in a directory

SYNOPSIS
       run-parts  [--test]  [--verbose] [--report] [--lsbsysinit] [--regex=RE]
       [--umask=umask] [--arg=argument] [--exit-on-error] [--help] [--version]
       [--list] [--reverse] [--] DIRECTORY

       run-parts -V

DESCRIPTION
       run-parts  runs  all  the  executable  files  named  within constraints
       described below, found in directory directory.  Other files and  direc‐
       tories are silently ignored.

       If neither the --lsbsysinit option nor the --regex option is given then
       the names must consist entirely of ASCII upper- and lower-case letters,
       ASCII digits, ASCII underscores, and ASCII minus-hyphens.

       If  the  --lsbsysinit  option  is given, then the names must not end in
       .dpkg-old  or .dpkg-dist or .dpkg-new or .dpkg-tmp, and must belong  to
       one  or more of the following namespaces: the LANANA-assigned namespace
       (^[a-z0-9]+$);   the   LSB   hierarchical   and   reserved   namespaces
       (^_?([a-z0-9_.]+-)+[a-z0-9]+$);  and  the  Debian cron script namespace
       (^[a-zA-Z0-9_-]+$).

       If the --regex option  is  given,  the  names  must  match  the  custom
       extended regular expression specified as that option's argument.

       Files  are  run  in  the  lexical  sort order (according to the C/POSIX
       locale character collation rules) of their names unless  the  --reverse
       option is given, in which case they are run in the opposite order.

我不知道这种方法/技巧是否适用于您的情况。但是，如果我理解正确的话，我认为这会有效。

[feddy@localhost ~]$ mkdir test
[feddy@localhost ~]$ cd test
[feddy@localhost test]$ ls
[feddy@localhost test]$ vi 0001-ko.sh
[feddy@localhost test]$ cp 0001-ko.sh 0002-ko.sh
[feddy@localhost test]$ cp 0001-ko.sh 0004-ko.sh
[feddy@localhost test]$ cp 0001-ko.sh 0005-ko file.sh
[feddy@localhost test]$ cp 0001-ko.sh 0008-ko.sh
[feddy@localhost test]$ ls
0001-ko.sh  0002-ko.sh  0004-ko.sh  0005-ko file.sh  0008-ko.sh

[feddy@localhost test]$ for i in *
> do
> bash "$i"
> done
file 0001-ko.sh
file 0002-ko.sh
file 0004-ko.sh
file 0005-ko file.sh
file 0008-ko.sh
[feddy@localhost test]$

或者

$ find . -iname "*.sh"|while read f; do bash "$f"; done
file ./0001-ko1.sh
file ./0002-ko1.sh
file ./0005-ko1 file.sh
file ./0005-ko1.sh

您可以编写一个脚本并使用它来按顺序（根据文件名中包含的数字，即 xxxx-abcdef）执行任意文件夹中的脚本。

如果我理解错了，请纠正我。
