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
其他回答
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

你可以使用
find .
递归搜索当前目录下的所有文件/dirs
然后您可以像这样通过xargs命令输出
find . | xargs 'command here'
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"
您可以通过管道，然后使用xargs来实现这一点。问题是您需要使用-I标志，它将用每个xargs传递的子字符串替换bash命令中的子字符串。
ls -d */ | xargs -I {} bash -c "cd '{}' && pwd"
您可能希望将pwd替换为您想在每个目录中执行的任何命令。
