如何只为特定类型的文件区分目录? [英] How do you diff a directory for only files of a specific type?

问题描述

我对diff命令有疑问 如果我要递归目录diff但仅针对特定文件类型，该怎么做?

I have a question about the diff command if I want a recursive directory diff but only for a specific file type, how to do that?

我尝试使用exclude选项，但只能使用一种模式:

I tried using the exclude option but can only use one pattern only:

$ diff /destination/dir/1 /destination/dir/2 -r -x *.xml

使用命令我只能排除xml文件类型，即使文件夹图像类型中有文件(png，gif，jpg)，txt，php等

with the command I can only exclude xml file type, even though there are files in the folder image type (png, gif, jpg), txt, php, etc

如何仅区分某些文件类型.

how to diff only certain file types.

推荐答案

您可以多次指定-x.

diff -x '*.foo' -x '*.bar' -x '*.baz' /destination/dir/1 /destination/dir/2

在info diff的比较目录"部分中(在我的系统上，我必须执行info -f /usr/share/info/diff.info.gz):

From the Comparing Directories section of info diff (on my system, I have to do info -f /usr/share/info/diff.info.gz):

要在比较目录时忽略某些文件，请使用'-x PATTERN"或"--exclude = PATTERN"选项.此选项将忽略任何文件 或基本名称与外壳模式PATTERN匹配的子目录. 与外壳程序不同，在文件名的开头以句点开头 在模式开头匹配通配符.你应该附上 用引号将PATTERN括起来，以使外壳程序不会对其进行扩展.例如， 选项 -x'*.[ao]'会忽略名称以'.a'结尾的任何文件，或者 ".o".

To ignore some files while comparing directories, use the '-x PATTERN' or '--exclude=PATTERN' option. This option ignores any files or subdirectories whose base names match the shell pattern PATTERN. Unlike in the shell, a period at the start of the base of a file name matches a wildcard at the start of a pattern. You should enclose PATTERN in quotes so that the shell does not expand it. For example, the option -x '*.[ao]' ignores any file whose name ends with '.a' or '.o'.

如果多次指定此选项，则会累积该选项.为了 例如，使用选项 -x'RCS'-x'*，v'忽略任何文件或 子目录，其基本名称为'RCS'或以'，v'结尾.

This option accumulates if you specify it more than once. For example, using the options -x 'RCS' -x '*,v' ignores any file or subdirectory whose base name is 'RCS' or ends with ',v'.
