Fetchmal email notif. on your prompt (pop, imap, etrn, odmr) [fixed]
Maybe this can help you (I'm refering to the previous post)

This is my question:
=============

1- I am using fetchmail
2- fetchmail allows you to "check" but not "fetch" with the -c flag
3- I thought I'd write a script to check for email, so that I get a text message
on my terminal when I get an email (because it's IMAP)

This is the script:
Code:
#!/usr/bin/env zsh

if echo `fetchmail -c -f ~path/to/my/fetchmailrc`| grep -q 'message'; then
  exit
else

missatge=$(echo `fetchmail -c -f ~path/to/my/fetchmail/fetchmailrc` | gawk '{print "you have "$2" "$3" waiting, my dear..."}')

echo -e "\033[34m\033[1m$missatge"

fi

This is my cronjob:

Code:
0-59/1 * * * * $HOME/bin/fetchmailnotification.sh

I have tested the script and it works just right.

However the cronjob is not showing anything. I thought it could be the > /dev/null or the > /dev/null 2>&1 if you want no e-mail ever.

I've tried removing these > but nothing

I was expecting to be prompted with the notification in my terminal whenever (after checking, say, once per minute, as stated in the cronjob) an email arrives but nothing...

any hint?

thanks

Pau

Cronjobs do not have any terminals associated with them. You cannot interact with a cronjob. Infact, the very purpose of cronjobs is to run without any manual intervention.

So do not expect any pop-ups or prompts from your cron job. Cron does not work that way.

ok... nice to learn new things...

I though cron would just run the script as it is and behave as I would expect bit it doesn't...

Do you have a solution then to run the script, say, every 20 minutes?

That's right. Anyway you could try something like:
Code:
echo "whatever" | write userX pts/X

Obviously you need to "guess" the terminal, but you can get that info from "who"...

Hi grial,

that's a promising thing indeed!

now my who yields

Code:
elachistos| who                                                                                                                              
pau      :0           2006-12-12 11:43
pau      pts/0        2006-12-12 11:44 (:0.0)
pau      pts/1        2006-12-12 12:29 (:0.0)
pau      pts/2        2006-12-12 13:54 (:0.0)
pau      pts/4        2006-12-12 13:58 (:0.0)

because I have opened 4 tabs on a terminal...

mmmh... I guess I could define a variable called pts and do a grep on "who" to have sent the message to all terminals... let me try it

thanks for the hint (I wasn't aware of write, by the way! nice BSD tool!)

Mmmh... there's a little problem... write is verbose

Code:
elachistos|                                                                                                                                  
Message from pau@elachistos on pts/2 at 14:20 ...
^[[34m^[[1mhola
EOF

and it doesn't understand the colour encoding (well, that's not very important, but I don't really like the "Message from blabla" and "EOF" ...

from the man it seems it's not possible to make it silent... Smilie
