是否有类似"watch"的命令?或"inotifywait"在Mac上? [英] Is there a command like "watch" or "inotifywait" on the Mac?

问题描述

我想在Mac(Snow Leopard)上观看一个文件夹，然后执行一个脚本(为它提供刚移入文件夹的文件名(作为参数... x.sh文件名")).

I want to watch a folder on my Mac (Snow Leopard) and then execute a script (giving it the filename of what was just moved into a folder (as a parameter... x.sh "filename")).

我有一个全部用bash(x.sh)编写的脚本，它将在输入$ 1上移动一些文件和其他内容.当新文件/文件夹移动/创建到目录中时，我只需要OSX给我文件名

I have a script all written up in bash (x.sh) that will move some files and other stuff on input $1 I just need OSX to give me the file name when new files/folders are moved/created into a dir.

有这样的命令吗?

推荐答案

fswatch

fswatch 是使用Mac OS X FSEvents API监视目录的小型程序. 收到有关对该目录进行任何更改的事件时，指定的 shell命令由/bin/bash

fswatch

fswatch is a small program using the Mac OS X FSEvents API to monitor a directory. When an event about any change to that directory is received, the specified shell command is executed by /bin/bash

如果您使用的是GNU/Linux， inotifywatch ( 大多数发行版上的inotify-tools软件包都提供了类似的功能 功能.

If you're on GNU/Linux, inotifywatch (part of the inotify-tools package on most distributions) provides similar functionality.

更新:fswatch现在可以在包括BSD，Debian和Windows在内的许多平台上使用.

Update: fswatch can now be used across many platforms including BSD, Debian, and Windows.

可以监视多个路径的新方法-适用于 1.x版及更高版本:

The new way that can watch multiple paths - for versions 1.x and higher:

fswatch -o ~/path/to/watch | xargs -n1 -I{} ~/script/to/run/when/files/change.sh

注意:如果不是-I{}，则-o输出的数字将添加到xargs命令的末尾.如果您确实选择使用该数字，请在命令中的任何位置放置{}.

Note: The number output by -o will get added to the end of the xargs command if not for the -I{}. If you do choose to use that number, place {} anywhere in your command.

版本0.x 的较旧方法:

fswatch ~/path/to/watch ~/script/to/run/when/files/change.sh

使用自制软件安装

自13年9月12日起，它已重新添加到自制软件-是！因此，更新您的公式列表(brew update)，然后所需要做的就是:

Installation with Homebrew

As of 9/12/13 it was added back in to homebrew - yay! So, update your formula list (brew update) and then all you need to do is:

brew install fswatch

没有自制软件的安装

在Terminal.app

cd /tmp
git clone https://github.com/alandipert/fswatch
cd fswatch/
make
cp fswatch /usr/local/bin/fswatch

如果您的系统上没有c编译器，则可能需要安装Xcode或Xcode命令行工具-两者都是免费的.但是，在这种情况下，您可能应该检出自制软件.

If you don't have a c compiler on your system you may need to install Xcode or Xcode command line tools - both free. However, if that is the case, you should probably just check out homebrew.
