编辑大量文本文件

发布于 2024-09-11 00:15:58 字数 314 浏览 7 评论 0原文

我有大约 350 个文本文件，其中包含硬盘上 5 个文件夹的全部内容。对于每个文件，我想删除每个文件开头和结尾处指定数量的字符。我对 AppleScript 不了解，但怀疑它可能适合我想要实现的目标。任何有关自动化此操作的帮助将不胜感激，因为手动编辑这些文件是一项艰巨的任务。非常感谢。

需要从每个文件的开头删除以下文本：

STARTTYPE:RGIN
MODEXP:NO

需要从每个文件的末尾删除以下文本：

REFACTORSCALE:2.0
ENDTYPE:FACTORED

原文

I have about 350 text files which comprise the entire contents of 5 folders on my HD. For each of these files, I would like to delete a specified number of characters at the start and end of each file. I have no knowledge of AppleScript but suspect it may be suitable for what I want to achieve. Any help on automating this would be greatly appreciated as manually editing these files is a daunting task. Thank you very much.

The following text needs to be removed from the start of each file:

STARTTYPE:RGIN
MODEXP:NO

The following needs to be removed from the end of each file:

REFACTORSCALE:2.0
ENDTYPE:FACTORED

OS X 是否有 unix 命令 sed ？它正是为了解决此类问题而设计的。

您可能会说（假设每个文件中要删除的文本都相同）：

sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' file_pattern
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' file_pattern

例如，假设一堆 .txt 文件需要在您的主目录下的这 5 个目录中完成这些编辑。你可以这样做：

sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_1/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_1/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_2/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_2/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_3/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_3/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_4/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_4/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_5/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_5/*.txt

Does OS X have the unix command sed? It was designed to solve precisely this type of problem.

You would say (assuming your text to remove is the same in every file):

sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' file_pattern
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' file_pattern

For example, lets say a bunch of .txt files need to have these edits done in these 5 directories under your home directory. You could do:

sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_1/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_1/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_2/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_2/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_3/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_3/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_4/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_4/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_5/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_5/*.txt
