bash 递归地grep zip文件列表中的模式

grep a pattern in list of zip files recursively

提问by Vijay

I am using the following command on command line for getting the pattern matched lines.

我在命令行上使用以下命令来获取模式匹配的行。

find . -name "*.gz"|xargs gzcat|grep -e "pattern1" -e "pattern2"

i need now to find only the file names where the pattern is present. how can i do it on command line?

我现在只需要找到存在模式的文件名。我怎样才能在命令行上做到这一点？

grel -lhas no use since i am using xargs gzcatbefore grep

grel -l没用，因为我xargs gzcat以前用过grep

for i in $(find . -name "*.gz"); do gzcat $i|grep -qe "n1" -e "n2" && echo $i; done

Check if you have zgrep available. And then, if yes:

检查您是否有可用的 zgrep。然后，如果是：

find . -name '*.gz' -exec zgrep -l -e ".." -e ".." {} +

If you don't have it - well, just copy it from some machine that has it (all linuxes I use have it by default) - it's a simple bash script.

如果您没有它 - 好吧，只需从拥有它的机器上复制它（我使用的所有 linux 默认都有它） - 这是一个简单的 bash 脚本。

Untested; does everything inside find so if you have loads of gz files you wont have performance problems as runs each gzcat/grep as soon as it finds files nothing is piped out:

未经测试；里面的所有东西都找到了，所以如果你有大量的 gz 文件，你不会有性能问题，因为一旦找到文件就运行每个 gzcat/grep 没有任何东西被管道输出：

find . -iname '*.gz' -exec bash -c 'gzcat  | grep -q -e "pattern1" -e "pattern2" && echo ' {} {} \;

In bash, I'd do something like this (untested):

在 bash 中，我会做这样的事情（未经测试）：

find . -name '*.gz' | while read f ; do gzcat $f | grep -q -e "pattern1" -e "pattern2" && echo $f ; done

ripgrep

ripgrep

Use ripgrep, for example, it's very efficient, especially for large files:

使用ripgrep，例如，它非常有效，尤其是对于大文件：

rg -z -e "pattern1" -e "pattern2" *.gz

or:

或者：

rg -z "pattern1|pattern2" .

or:

或者：

rg -zf pattern.file .

^{Where pattern.fileis a file containing all your patterns separated by a new line character.}

^{pattern.file包含由换行符分隔的所有模式的文件在哪里。}

-z/--search-zipSearch in compressed files (such as gz, bz2, xz, and lzma).

-z/--search-zip在压缩文件中搜索（如gz，bz2，xz，和lzma）。

grep/zgrep/zegrep

grep/ zgrep/zegrep

Use zgrepor zegrepto look for pattern in compressed files using their uncompressed contents (both GNU/Linux and BSD/Unix).

使用zgrep或使用zegrep压缩文件的未压缩内容（GNU/Linux 和 BSD/Unix）在压缩文件中查找模式。

On Unix, you can also use grep(which is BSD version) with -Z, including -zon macOS.

在 Unix 上，您还可以使用grep（BSD 版本）和-Z，包括-z在 macOS 上。

Few examples:

几个例子：

zgrep -E -r "pattern1|pattern2|pattern3" .
zegrep "pattern1|pattern2|pattern3" **/*.gz
grep -z -e "pattern1" -e "pattern2" *.gz # BSD/Unix only.

^{Note: When you've globbing option enabled, **checks the files recursively, otherwise use -r.}

^{注意：当您启用 globbing 选项时，**递归检查文件，否则使用-r.}

-R/-r/--recursiveRecursively search subdirectories listed.

-E/--extended-regexpInterpret pattern as an extended regular expression (like egrep).

-Z(BSD), -z/--decompress(BSD/macOS) Force grep to behave as zgrep.

-R/ -r/--recursive递归搜索子目录上市。

-E/ 将--extended-regexp模式解释为扩展的正则表达式（如egrep）。

-Z( BSD), -z/ --decompress( BSD/macOS) 强制 grep 表现为zgrep.
