Script scheduling problem using "at" command
Hello!
I'm writing a shell script that will monitor if a server is up or down.
I would like to use the command "at" inside of my script to reschedule the script to run in 2 minutes but I can't pass parameters to my script and this is my problem...
This is the idea behind the script:
1. The script run in "normal mode" and check if the server is up. If the server is not responding, the script go to step 2.
2. Schedule itself to run in two minutes in "prealert mode"
3. When running in "prealert mode", the script check if the server is still not responding and if not, send a alert to the network administrator.
Does anybody know how to pass parameters to a commmand or script while using the "at" command. I know I can put everything in a file and make at use that file but I would prefer not to... Any suggestion?
Syntax example to execute the script:
./test_ping prealert server1.test.com
Here is a sample of my script:
#!/bin/bash
#Script to test network connectivity
#By Benoit Charbonneau
#March 4th 2005
#Parameters ex.: test_ping mode(normal|prealert) server
log="../monitoring.log"
date=$(date)
path=$(pwd)
script=$path/test_ping
ping -c1 -w2 $2 > /dev/null
error=$?
if [ $1 = "normal" ]; then
if [ $erreur != 0 ] ; then
at -f "$script prealert $2" now + 2 minute
# My problem is here
echo $date $2 ping error - A prealert has been open >> $log
else
echo $date $2 ping ok >> $log
fi
fi
if [ $1 = "prealert" ]; then
...
Sorry if i'm not clear enought. English is not my first language...
Thank you for your help!

installsieve
INSTALLSIEVE(1) General Commands Manual INSTALLSIEVE(1)
*
NAME
installsieve - user utility for managing sieve scripts
SYNOPSIS
installsieve
DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server.
OPTIONS
-v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.
-l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
script.
-p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.
-i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully
putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
sieve names may not contain a '.'.
-a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..
-d <name> Delete the sieve script on the server with <name>.
-m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.
-g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is
overwritten.
-u <user> Userid/Authname to use for authentication; by default, the current user.
