如何进入每个目录并执行命令? [英] How to go to each directory and execute a command?

问题描述

如何编写一个 bash 脚本，该脚本遍历 parent_directory 中的每个目录并执行每个目录中的命令.

How do I write a bash script that goes through each directory inside a parent_directory and executes a command in each directory.

目录结构如下:

parent_directory(名称可以是任何东西 - 不遵循模式)

parent_directory (name could be anything - doesnt follow a pattern)

• 001(目录名称遵循此模式)
  • 0001.txt(文件名遵循此模式)
  • 0002.txt
  • 0003.txt
  • 0001.txt
  • 0002.txt
  • 0003.txt
  • 0004.txt
  • 0001.txt

  目录数量未知.

  推荐答案

  当你当前的目录是 parent_directory 时，你可以进行以下操作:

  You can do the following, when your current directory is parent_directory:

  for d in [0-9][0-9][0-9]
  do
      ( cd "$d" && your-command-here )
  done
  

  ( 和 ) 创建一个子shell，所以当前目录不会在主脚本中改变.

  The ( and ) create a subshell, so the current directory isn't changed in the main script.
