Bash script for inotifywait - How to write deletes to log file, and cp close_writes?
提问by Buttle Butkus
I have this bash script:
我有这个 bash 脚本：
#!/bin/bash
inotifywait -m -e close_write --exclude '\*.sw??$' . |
#adding --format %f does not work for some reason
while read dir ev file; do
cp ./"$file" zinot/"$file"
done
~
Now, how would I have it do the same thing but also handle deletes by writing the filenames to a log file? Something like?
现在，我如何让它做同样的事情，但也通过将文件名写入日志文件来处理删除？就像是？
#!/bin/bash
inotifywait -m -e close_write --exclude '\*.sw??$' . |
#adding --format %f does not work for some reason
while read dir ev file; do
# if DELETE, append $file to /inotify.log
# else
cp ./"$file" zinot/"$file"
done

EDIT:
编辑：
By looking at the messages generated, I found that inotifywait generates CLOSE_WRITE,CLOSEwhenever a file is closed. So that is what I'm now checking in my code.
I tried also checking for DELETE, but for some reason that section of the code is not working. Check it out:
通过查看生成的消息，我发现 inotifywait 会CLOSE_WRITE,CLOSE在文件关闭时生成。这就是我现在检查我的代码的内容。我也尝试检查DELETE，但由于某种原因，该部分代码不起作用。一探究竟：
#!/bin/bash
fromdir=/path/to/directory/
inotifywait -m -e close_write,delete --exclude '\*.sw??$' "$fromdir" |
while read dir ev file; do
if [ "$ev" == 'CLOSE_WRITE,CLOSE' ]
then
# copy entire file to /root/zinot/ - WORKS!
cp "$fromdir""$file" /root/zinot/"$file"
elif [ "$ev" == 'DELETE' ]
then
# trying this without echo does not work, but with echo it does!
echo "$file" >> /root/zinot.txt
else
# never saw this error message pop up, which makes sense.
echo Could not perform action on "$ev"
fi
done
In the dir, I do touch zzzhey.txt. File is copied. I do vim zzzhey.txtand file changes are copied. I do rm zzzhey.txtand the filename is added to my log file zinot.txt. Awesome!
在目录中，我做touch zzzhey.txt. 文件被复制。我这样做vim zzzhey.txt并复制了文件更改。我这样做rm zzzhey.txt了，文件名被添加到我的日志文件中zinot.txt。惊人的！

You need to add -e deleteto your monitor, otherwise DELETEevents won't be passed to the loop. Then add a conditional to the loop that handles the events. Something like this should do:
您需要添加-e delete到您的监视器，否则DELETE事件将不会传递到循环。然后向处理事件的循环添加条件。这样的事情应该做：
#!/bin/bash
inotifywait -m -e delete -e close_write --exclude '\*.sw??$' . |
while read dir ev file; do
if [ "$ev" = "DELETE" ]; then
echo "$file" >> /inotify.log
else
cp ./"$file" zinot/"$file"
fi
done
