问题描述
使用这组命令，什么是{}和\; ？
With this set of commands, what are the {} and \; characters for?
find . -name '*.clj' -exec grep -r resources {} \;
推荐答案
请参阅。 （特别是 -exec 部分）
See man find. (particular the part about -exec)
使用 -exec 为每个找到的文件运行命令， {} 被替换为找到的每个文件的名称，命令终止 \;
When using -exec to run a command on each of the files found, the {} is replaced with the name of each file found, and the command is terminated by \;
在您的示例中，在当前目录下找到的所有文件（。），匹配 *。clj 将有命令 grep -r resources
In your example, all files found under the current directory (.), matching the name *.clj will have the command grep -r resources run on them (to find the string resources if it exists in each of those files).
实际上有些多余，因为 c $ c> -r 用于递归搜索子目录，这是找到已经在做。
It's actually somewhat redundant, since -r is for recursively searching subdirectories, and that's what find is already doing.
