Count files in dir then move that many files in a script?

Hello World,

K, this is what I got - from a crontab run a script (understand that part), this script needs to count the amount of files in /outgoing/, then take 30 less that number, and move that many files from /readycalls/.

I need to keep the asterisk outgoing que full of .call files with out having to many in there at any given time.

Any help would be awesome!!

I don't know anything about astrisk and its inner workings,
but to me moving 30 random files from a spool sounds like
trouble in the making. Can you be more specific with your
requirements?

Cheers,
Tink

In bash I use

Code:

#!/bin/bash
TOTAL_CALLS_CMD=$(find /outgoing/ -mindepth 1 -maxdepth 1 -type f | wc -l)
declare -i REDUCED=$TOTAL_CALLS_CMD-30

echo Total: $TOTAL_CALLS_CMD
echo Reduced: $REDUCED

Then you could use a while loop for while TOTAL_CALLS_CMD -gt $REDUCED move a file or however you need to do that.

You should also of course make sure there is more than 30 to begin with, etc.

Thanks for the code! I will see if I can make that work.

In regards to how and why, its actually a very simple procedure. Asterisk has a directory /var/spool/asterisk/outgoing/ , when you drop a properly formated .call file into the dir, it follows the specified .call file and makes an outbound call. Its how you initiate outbound calling in asterisk.

That being said, I am building an alert system for the public school district I administer, this system is managed via a web based 'wizard' that I have made. It also send sms txts, and emails to registered users. When the alert is configured, it drops all of the appropriate .call files into a temp directory, a coulple thousand. Then a cron job moves those files into the outgoing directory every 1 min. However, if there are more calls trying to get made than the amount of channels (phone lines) available, it will just skip the call. So, If i dropped in 2000 call files, with only 40 channels available, it would only make 40 calls. So, I need just need to drop in no more than 30-40 at a time. Hence the requested bash script.
