可以find命令的＆QUOT; EXEC＆QUOT;功能在后台启动的程序？ [英] Can the find command's "exec" feature start a program in the background?

问题描述

我想这样做是这样的：

find . -iname "*Advanced*Linux*Program*" -exec kpdf {} & \;

可能吗？可用一些其他类似的方法是什么？

Possible? Some other comparable method available?

推荐答案

首先，你输入它不会工作，因为shell会间preT为

Firstly, it won't work as you've typed, because the shell will interpret it as

find . -iname "*Advanced*Linux*Program*" -exec kpdf {} &
\;

这是一个无效的发现在后台运行，其次是不存在的命令。

which is an invalid find run in the background, followed by a command that doesn't exist.

即使逃脱这是行不通的，因为找到-exec 实际上 EXEC S中的参数列表中给出，而不是它给予一个shell（这是实际处理＆安培; 为一个后台）。

Even escaping it doesn't work, since find -exec actually execs the argument list given, instead of giving it to a shell (which is what actually handles & for backgrounding).

一旦你知道的是的问题，你所要做的就是启动一个shell给这些命令：

Once you know that that's the problem, all you have to do is start a shell to give these commands to:

find . -iname "*Advanced*Linux*Program*" -exec sh -c '"$0" "$@" &' kpdf {} \;

在另一方面，给你想要做什么，我会建议之一

On the other hand, given what you're trying to do, I would suggest one of

find ... -exec kfmclient exec {} \;  # KDE
find ... -exec gnome-open {} \;      # Gnome
find ... -exec xdg-open {} \;        # any modern desktop

将打开默认程序的文件由您的桌面环境有关。

which will open the file in the default program as associated by your desktop environment.
