在tar文件中执行grep操作而不解压 [英] Performing grep operation in tar files without extracting

问题描述

我有包含特定模式的文件列表，但这些文件已被压缩.现在我想在 tar 文件中搜索模式，并在不提取文件的情况下知道哪些文件包含该模式.

I have list of files which contain particular patterns, but those files have been tarred. Now I want to search for the pattern in the tar file, and to know which files contain the pattern without extracting the files.

有什么想法...?

推荐答案

tar 命令有一个 -O 开关，可以将您的文件提取到标准输出.所以你可以将这些输出通过管道传输到 grep/awk

the tar command has a -O switch to extract your files to standard output. So you can pipe those output to grep/awk

tar xvf  test.tar -O | awk '/pattern/{print}'

tar xvf  test.tar -O | grep "pattern"

例如返回找到的一种模式的文件名

eg to return file name one pattern found

tar tf myarchive.tar | while read -r FILE
do
    if tar xf test.tar $FILE  -O | grep "pattern" ;then
        echo "found pattern in : $FILE"
    fi
done
