emacs编译：在后台调用脚本

[英]emacs compilation: call a script in background

原文 2013-02-19 22:40:07 3 1 bash/ emacs/ compile-mode

I have a script (let's call it ding ) which plays a sound in the background (essentially just calls paplay <file> & ). 我有一个脚本（我们称其为ding ），该脚本在后台播放声音（实际上只是调用paplay <file> & ）。 I wish to call this from emacs after I finish compiling something, like so: 我希望在完成编译后从emacs调用它，如下所示：

Mx compile , make && ding Mx compile ， make && ding

Unfortunately because paplay is called in the background, nothing happens (no sound is played). 不幸的是，因为在后台调用了paplay ，所以什么也没发生（没有声音播放）。 If I remove the & from ding , the sound is played just fine. 如果我从ding删除& ，声音会很好地播放。

Why does this happen, and is there a way to get a script to execute in the background in compilation mode (without making it a foreground job)? 为什么会发生这种情况，有没有办法让脚本在编译模式下在后台执行（而不使其成为前台工作）？

Emacs will close the commands' output when the commands finish, and chances are paplay doesn't like that. 当命令完成时，Emacs将关闭命令的输出，并且有可能paplay不喜欢这样。 Try nohup paplay ... & 尝试nohup paplay ... &
