I would like to know

Is it possible to get a notification as pop-up in linux

when a folder with extension '.aqs' written

a popup should come

as " The folder has been written "

Thank you in advance

I not fully understand, but if you want to show a popup window when somewhere a folder with .aqs extension has been written, then you can use "inotify" mechanism to react on filesystem change and "xmessage" to display message.

thats fine....wht could be done if inotify is not present in the system

You want to inspect a specific directory or whole partition?

I will expalain

what happens is I used to submit jobs in server and run job wud be written in the directory

/home/balnair/transfer/

as a set of files in the folder 'scs.aqs'

So I would like to get the notification such as
" Your job has been run " once it is finished

Once the job is run,

Files will be located as shown below

/home/balnair/transfer/scs.aqs

abc.op2
cvf.f06
bgy.f04
asa.test...

Hope you get my requirement

Better option would be to process who write these files will signal somehow that it finishes. For example it can output to known file text for example 1 when it begin, 2 when it end. If you have no control of this process, and really you can only react on created file in specified directory, then you can use something like that:

Code:

#!/bin/bash

while [[ $(ls /home/balnair/transfer/scs.aqs | grep -c '.*') == 0 ]]
do
    sleep 5
done
xmessage 'Your job has been run.'

But, because you don't known how many files will be created you will be notified when first file will be, so I think this will be useless if these files are created slowly.

how would we make this script always running on background?..that is whenever a folder is created with .aqs extension I should get the notification

bal_nair1 · 07-30-2012, 04:33 AM

HOW WOULD WE MAKE THIS SCRIPT RUNNING IN BACKGROUND ALWAYS.........SO THAT WHENEVER A FOLDER WITH EXTENSION .aqs IS WRITTEN

MESSAGE SHOULD COME

You can enclose it to forever loop:

Code:

#!/bin/bash

while true
do
  while [[ $(ls /home/balnair/transfer/scs.aqs | grep -c '.*') == 0 ]]
  do
    sleep 5
  done
  xmessage 'Your job has been run.'
done

And run it in from your X session autostart place with ampersand character "&" on the end. This script react on created file in this directory. If you want to react on any directory with .aqs extension then change while line with this:

Code:

while [[ $(ls -d /home/balnair/transfer/*.aqs | grep -c '.*') == 0 ]]
