所有目录中的grep [英] grep in all directories

问题描述

我有一个名为XYZ的目录，里面有目录ABC，DEF，GHI.我想在所有目录中的所有* .c中搜索模式'writeText'(即XYZ，XYZ/ABC，XYZ/DEF和XYZ/GHI)我可以使用什么grep命令?

I have a directory named XYZ which has directories ABC, DEF, GHI inside it. I want to search for a pattern 'writeText' in all *.c in all directories (i.e XYZ, XYZ/ABC, XYZ/DEF and XYZ/GHI) What grep command can I use?

如果我只想在XYZ，XYZ/ABC，XYZ/GHI中搜索而不在XYZ/DEF中搜索，我可以使用什么grep命令?

Also if I want to search only in XYZ, XYZ/ABC, XYZ/GHI and not XYZ/DEF, what grep command can I use?

谢谢！

推荐答案

grep -R --include="*.c" --exclude-dir={DEF} writeFile /path/to/XYZ

• -R 表示递归，因此它将进入您要遍历的目录的子目录中
• -include ="*.c" 的意思是查找以 .c 结尾的文件"
• -exclude-dir = {DEF} 的意思是排除名为 DEF 的目录.如果要排除多个目录，请执行以下操作:-exclude-dir = {DEF，GBA，XYZ}
• writeFile 是您要抓取的模式
• /path/to/XYZ 是您要grep通过的目录的路径.
• -R means recursive, so it will go into subdirectories of the directory you're grepping through
• --include="*.c" means "look for files ending in .c"
• --exclude-dir={DEF} means "exclude directories named DEF. If you want to exclude multiple directories, do this: --exclude-dir={DEF,GBA,XYZ}
• writeFile is the pattern you're grepping for
• /path/to/XYZ is the path to the directory you want to grep through.

请注意，这些标志适用于GNU grep ，如果您使用的是BSD/SysV/AIX grep ，则可能会有所不同.如果您使用的是Linux/GNU grep utils，那么应该没问题.

Note that these flags apply to GNU grep, might be different if you're using BSD/SysV/AIX grep. If you're using Linux/GNU grep utils you should be fine.
