How to use inotifywait in a non-blocking way and mail the results?

I've tried several times to test my script, but with no success. This is the script:

zenity --question --text "my text"

if [ $? -eq 1 ]; then

    zenity --warning --text "my text"

else

    ping -n -c1 192.168.180.112

    # print result (0 se existir)

    echo $?

    if [ $? -eq 0 ]; then

        scp -r ~/Documents/Processo/CONCLUIDO/* [email protected]:/home/posto-ensaios/Documents/Processo

        fileName=$(inotifywait -e moved_from /home/posto-11v/Documents/Processo/CONCLUIDO | sed -r 's/^.*MOVED_FROM(,ISDIR)*s+(.*)$/2/g')

        mail -s "$fileName" [email protected] < ~/Documents/personaproject/Programa/scripts/mail.txt

        mv --backup ~/Documents/Processo/CONCLUIDO/* ~/Documents/personaproject/processos_terminados    

        zenity --info --text="my text"

    else

        zenity --warning --text "my text"

    fi

fi

I've tried to run with the sleep command with "pipe" after sed and to change the order of the commands. When running the script in their terminal the problem is that inotify always keeps waiting for an action...

I need to guarantee that files are copied, moved and the $filename is sent in email...

Any help?

Thanks!

If you'd like to send a mail everytime a file has been moved from the watched directory, you'll need to set up a different process monitoring this and sending the mail.

For the reasons you have just described, it doesn't matter where you put the inotifywait command, since the mv command does not happen at the same time, you won't catch the required event.

But if you watched the directory from another process, the moving takes place while you're watching and you can detect any changes.

By building on the previous example, you can start with the following sample script.

while true

do

    fileName=$(inotifywait -e moved_from /home/posto-11v/Documents/Processo/CONCLUIDO | sed -r 's/^.*MOVED_FROM(,ISDIR)*s+(.*)$/2/g')

    mail -s "$fileName" [email protected] < ~/Documents/personaproject/Programa/scripts/mail.txt

done

Please fill in the required details, it works basically the same as the previous example.

Note:

There are a few caveats, for example it might miss some moves while the mail is sent. It depends on the quantity and frequency of moves.
