如何打印導致fswatch做某事的文件路徑

Question

我使用fswatch在文件更改時採取一些操作。我用下面的命令：

fswatch -o -r '.' | while read MODFILE 
do 
    echo 'Some file changed, so take some action' 
done 

這工作得很好，如果我改變了幾個文件，我看到在終端如下：

Some file changed, so take some action 
Some file changed, so take some action 
Some file changed, so take some action 
etc. 

但我也想知道哪個文件造成的實際行動。所以，我檢查了fswatch手冊，它顯示以下內容：

fswatch writes a record for each event it receives containing: 
    -  The timestamp when the event was received (optionally). 
    -  The path affected by the current event. 
    -  A space-separated list of event types (see EVENT TYPES). 

但正如我說沒有看到我的終端上市的事情。有誰知道我能如何顯示「受當前事件影響的路徑。」「？

所有的技巧都歡迎！

Answer 1

當然，使用此：

fswatch --batch-marker=EOF -xn . | while read file event; do 
    echo $file $event 
    if [ $file = "EOF" ]; then 
     echo TRIGGER 
    fi 
done 

如果你想受影響的文件名保存在列表中，你可以做這樣的：

#!/bin/bash 
fswatch --batch-marker=EOF -xn . | while read file event; do 
    if [ $file = "EOF" ]; then 
     echo TRIGGER 
     echo Files: "${list[@]}" 
     list=() 
    else 
     echo $file $event 
     list+=($file) 
    fi 
done
