在OSX终端中批量重命名文件 [英] Batch renaming files in OSX terminal

问题描述

我正在尝试重命名文件，例如screen-0001.tif到0001.tif，使用此SO问题中的方法:

I'm trying to rename files e.g. screen-0001.tif to 0001.tif using the approach in this SO question:

for file in *.tif
do
  echo mv "$file" "${screen-/file}"
done

无法更改任何内容.感谢我出了错的想法.

fails to change anything. Grateful for an idea where I'm going wrong.

推荐答案

两件事:

1. 您正在回显命令，而不是实际执行它们.在执行大规模重命名时，我将执行此操作，以确保命令正确运行.我可以将输出重定向到一个文件，然后将该文件用作Shell脚本.
2. 替换错误.有两种方法:

1. You're echoing the commands and not actually executing them. I will do this when I do massive renames just to make sure that the command works correctly. I can redirect the output to a file, and then use that file as a shell script.
2. The substitution is wrong. There are two ways:

1. 最左边的过滤器${file#screen-}.
2. 替换:${file/screen/}

1. Left most filter ${file#screen-}.
2. Substitution: ${file/screen/}

环境变量的名称始终排在最前面.然后是模式类型，然后是模式

The name of the environment variable always goes first. Then the pattern type, then the pattern

这是我要这样做的方式:

Here's how I would do this:

$ for file in *.tif
> do
>   echo "mv '$file' '${file#screen-}'"
> done | tee mymove.sh   # Build a shell script 
$ vi mymove.sh           # Examine the shell script and make sure everything is correct
$ bash mymove.sh         # If all is good, execute the shell script.
