bash脚本来替换文件名中的空格 [英] Bash script to replace spaces in file names

问题描述

谁能推荐一个安全的解决方案，以递归替换文件下划线和目录名从给定根目录开始的空间？例如，

Can anyone recommend a safe solution to recursively replace spaces with underscores in file and directory names starting from a given root directory? For example,

$ tree
.
|-- a dir
|   `-- file with spaces.txt
`-- b dir
    |-- another file with spaces.txt
    `-- yet another file with spaces.pdf

变为

$ tree
.
|-- a_dir
|   `-- file_with_spaces.txt
`-- b_dir
    |-- another_file_with_spaces.txt
    `-- yet_another_file_with_spaces.pdf

感谢您的答案;他们似乎都工作。我挑了一个由丹尼斯为主要答案，因为在我看来，最简单的，即使它需要两个步骤。

Thanks for the answers; they all seem to work. I picked the one by Dennis as the main answer because it seems to me the simplest, even though it takes two steps.

推荐答案

使用改名（又名 preNAME ），这是一个Perl脚本，这可能是您的系统上了。做它在两个步骤：

Use rename (aka prename) which is a Perl script which may be on your system already. Do it in two steps:

find -name "* *" -type d | rename 's/ /_/g'    # do the directories first
find -name "* *" -type f | rename 's/ /_/g'

根据于尔根的答案，并能够处理的文件和目录的多层纵身使用<$ C的修订版1.5 1998年12月18日16时16分31秒1元的版本$ C>的/ usr / bin中/重命名（Perl脚本）：

Based on Jürgen's answer and able to handle multiple layers of files and directories in a single bound using the "Revision 1.5 1998/12/18 16:16:31 rmb1" version of /usr/bin/rename (a Perl script):

find /tmp/ -depth -name "* *" -execdir rename 's/ /_/g' "{}" \;
