bash:-exec在find命令中& [英] bash: -exec in find command and &

问题描述

我要跑步:

./my_script.py a_file &

在当前文件夹中所有以 .my_format 结尾的文件上的

...，所以我这样做:

... on all files in the current folder that end with .my_format, so I do:

find . -type f -name "*.my_format" -exec ./my_script {} & \;

但是它不起作用.我应该如何在 -exec 参数中包含& ?

but it doesn't work. How should I include & in the -exec parameter?

推荐答案

尝试一下:

$ find . -type f -name "*.my_format" -exec sh -c './my_script {} &' \;

您的尝试不起作用的最可能原因是因为find使用 exec(3)系列的标准c库调用之一执行了命令，而该标准c库调用不了解作业控制-& 符号.Shell确实了解在后台运行此命令"，因此 -exec sh ... 调用

The mostly likely reason your attempt didn't work is because find executes the command using one of the exec(3) family of standard c library calls which don't understand job control - the & symbol. The shell does understand the "run this command in the background" hence the -exec sh ... invocation
