我如何编写一个bash脚本，遍历parent_directory内的每个目录，并在每个目录中执行命令。
目录结构如下:
Parent_directory(名称可以是任何东西-不遵循模式) 001(目录名称遵循此模式) 0001.txt(文件名遵循此模式) 0002.三种 0003.三种 002 0001.三种 0002.三种 0003.三种 0004.三种 003 0001.三种 目录数量未知。

我不明白文件的格式，因为你只想遍历文件夹…你在找这样的东西吗?
cd parent
find . -type d | while read d; do
ls $d/
done

如果顶层文件夹是已知的，你可以这样写:
for dir in `ls $YOUR_TOP_LEVEL_FOLDER`;
do
for subdir in `ls $YOUR_TOP_LEVEL_FOLDER/$dir`;
do
$(PLAY AS MUCH AS YOU WANT);
done
done
在$上(想玩多少就玩多少);你可以放尽可能多的代码。
注意，我没有在任何目录上使用“cd”。

While one liners are good for quick and dirty usage, I prefer below more verbose version for writing scripts. This is the template I use which takes care of many edge cases and allows you to write more complex code to execute on a folder. You can write your bash code in the function dir_command. Below, dir_coomand implements tagging each repository in git as an example. Rest of the script calls dir_command for each folder in directory. The example of iterating through only given set of folder is also include.
#!/bin/bash
#Use set -x if you want to echo each command while getting executed
#set -x
#Save current directory so we can restore it later
cur=$PWD
#Save command line arguments so functions can access it
args=("$@")
#Put your code in this function
#To access command line arguments use syntax ${args[1]} etc
function dir_command {
#This example command implements doing git status for folder
cd $1
echo "$(tput setaf 2)$1$(tput sgr 0)"
git tag -a ${args[0]} -m "${args[1]}"
git push --tags
cd ..
}
#This loop will go to each immediate child and execute dir_command
find . -maxdepth 1 -type d \( ! -name . \) | while read dir; do
dir_command "$dir/"
done
#This example loop only loops through give set of folders
declare -a dirs=("dir1" "dir2" "dir3")
for dir in "${dirs[@]}"; do
dir_command "$dir/"
done
#Restore the folder
cd "$cur"
for p in [0-9][0-9][0-9];do
(
cd $p
for f in [0-9][0-9][0-9][0-9]*.txt;do
ls $f; # Your operands
done
)
done
当当前目录为parent_directory时，可以执行以下操作:
for d in [0-9][0-9][0-9]
do
( cd "$d" && your-command-here )
done
(和)创建一个子shell，因此当前目录不会在主脚本中更改。
