[kaspareov]

Hello All,

I am trying to write a script which will check and informed user that there is a new email. Is any one tell me, how can i find that?

Thanking You,

Hello

Take a look at mailcheck:

mailcheck

It should be able to handle the task of checking mail for you, and other options are available online.

Please check my code is as follow

 while true
        do
                mail -E
                stat=`echo $status`
                echo $stat
                if [  "$stat" -eq 0 ]
                then
                        echo There is new e-Mail to read.
                        exit 1
                else
                        echo No new e-Mail.
                        sleep 30
                        continue
                fi
        done

It's everytime saying that you have new mail. Infact there is no email.

Hi.

Perhaps this will help:
Exit status $?

       ?      Expands to the status of the most recently executed foreground
              pipeline.

-- excerpt from man bash

As far as I know, $status is for the csh-family shells.

Bet wishes ... cheers, drl

No, it's not working either.

Hi.

Saying it does not work and similar responses is not useful.

If you have changed your code, post it, along with results. If you are getting an error message, post it verbatim ... cheers, drl

I was getting error "test: unknown operator 0", but I have resolved it. Now I have some other problem. It is always saying you have new email eventhough there is no email (empty) in mailbox. Please have look my code as follow:

#!/usr/bin/sh

# Program to check whether a new email during 30 seconds or not

        while true
        do
                mail -E
                echo $?
                if [ "echo $?" -gt "0" ]
                then
                        echo There is no e-Mail to read.
                        sleep 30
                        continue 1
                else
                        echo You have new e-Mail.
                        exit 1
                fi
        done

[output]
1
You have new e-Mail.

Hi.

This script describes the computing environment, then shows how to test the result of an operation, both with failure and success:

#!/usr/bin/env bash

# @(#) s1	Demonstrate exit status and checking.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C

pe
status=$?
pe " Initial exit status = $status"

pe
garbage
status=$?
pe " Status after command not found = $status"

pe
status=$?
pe " Current status is $status"
if [ $status -eq 0 ]
then
  pe " Status was zero."
fi

pe
ls no-such-file
status=$?
if [ $status -eq 0 ]
then
  pe " Status was zero."
else
  pe " Status was not zero: $status"
fi

exit 0

producing:

% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny) 
GNU bash 3.2.39

 Initial exit status = 0

./s1: line 18: garbage: command not found
 Status after command not found = 127

 Current status is 0
 Status was zero.

ls: cannot access no-such-file: No such file or directory
 Status was not zero: 2

I'm confident in your ability to see the similarities between my code and what yours should be.

Remember that echo, printf and man pages are your friends.

Best wishes ... cheers, drl
