搜索一系列目录bash脚本

Question

I have written (tried to) this small bash script for searching through a range of directories.

#!/bin/bash
shopt -s nullglob
for file in [ac]*/blarg
do 
   echo $file
   done

This script searches through directories starting with "a" through "c" for "blarg". It only goes one level deep. How can I make it step through all directories it might encounter, and not just the root of the directories with the starting letter.

Also, is this question supposed to go here at stackoverflow or would superuser be more suitable?

Thanks

Answer 1

if you have Bash 4.0 you can try globstar

#!/bin/bash
shopt -s nullglob
shopt -s globstar
for file in [ac]*/**/blarg
do 
   echo $file
done

Answer 2

on the command line ths will do your purpose.so why to go for a script?

find ./[ac]*/ -name "blarg"

if you still need a script:

#!/bin/bash
shopt -s nullglobi
for file in `find ./[ac]*/ -name "blarg"`
do
echo $file
done

Answer 3

echo `find blarg`

替换该行，您将在[ac] *下找到名为blarg的所有文件。
