我有以下的目录结构,例如:
I have the following directory structure for example:
/test_dir/d /test_dir/d/cron /test_dir/d/cache /test_dir/d/...(more sub dirs) /test_dir/tree /test_dir/tree/a /test_dir/tree/a/a1 /test_dir/tree/a/a2 ...(and so on for b/ and c/ )我已经写了下面的bash脚本,有效地传播到 / test_dir 的第二个级别,以便将达到 / test_dir / D / cron的或 / test_dir /树/ A ,但不会走得更远。我想不通,为什么递归脚本将不会进一步旅行可以有人请调试脚本,并指出我的错误?
I've written the following bash script that effectively travels to the second level of /test_dir so it will reach /test_dir/d/cron or /test_dir/tree/a but will not go further. I cannot figure out why the recursive script will not travel further can someone please debug the script and point out my error?
这里是我写的:
#!/bin/bash #script to recursively travel a dir of n levels function traverse() { for file in `ls $1` do #current=${1}{$file} if [ ! -d ${1}${file} ] ; then echo " ${1}${file} is a file" else #echo "entering recursion with: ${1}${file}" traverse "${1}/${file}" fi done } function main() { traverse $1 } main $1下面是输出:
/test_dir/a is a file /test_dir/b is a file /test_dir//dcache is a file /test_dir//dcron is a file /test_dir//dgames is a file /test_dir//dlib is a file /test_dir//dlog is a file /test_dir//drun is a file /test_dir//dtmp is a file /test_dir/movies is a file /test_dir//treea is a file /test_dir//treeb is a file /test_dir//treec is a file /test_dir//treed is a file我知道有可能更优雅的一行命令来做到这一点。但是我试图做到这一点在这个明确的方式。我对这个职位的长度道歉。
I know there are probably more elegant one line commands to do this. But im trying to do it in this explicit manner. I apologize for the length of this post.
编辑:使用横$ {1} / $ {}文件
推荐答案若干问题的脚本。它应该是这样的:
Several problems with the script. It should be like this:
#!/bin/bash #script to recursively travel a dir of n levels function traverse() { for file in "$1"/* do if [ ! -d "${file}" ] ; then echo "${file} is a file" else echo "entering recursion with: ${file}" traverse "${file}" fi done } function main() { traverse "$1" } main "$1"不过,递归遍历目录正确的方法是使用find命令:
However, the correct way to recursively traverse a directory is by using the find command:
find . -print0 | while IFS= read -r -d '' file do echo "$file" done更多推荐
