Top Forums Shell Programming and Scripting Expect command when triggered by launchd Post 302734817 by rowie718 on Friday 23rd of November 2012 01:43:06 AM

Figured it out!

It wasnt anything about launchd session types or anything else. After reading a bit of the book "Exploring Expect", I followed up on a hint they gave about adding another expect line so the expect command doesnt end as soon as the first match is made and responded to. Here is the code that works, which is in a larger bash script:

Code:
/usr/bin/expect -c '
spawn slapconfig -backupdb "'"${recover}/_OD_Backup_${date}"'"
sleep 10
expect "Enter archive password:"
send "'"${passwd}\r"'"
expect "============"
' >${logfile}

For context, and hopefully to help other folks backing up mac servers, here is the larger bash script (which is a modified/updated older script I found online). It has been tested on 10.8.2 and works whether triggered via command line or launchdaemon (must be run as root). Adjust parameters at top of the script. The two variables with brackets (< and >) are required:

Code:
#!/bin/bash

# Path to the root folder where the backups will be stored
# This path should not be on the root volume, and not accessible
# to non-administrators

recover_path="<path/to/backup/folder>"

# Log file location

logfile="/Library/Logs/Server_Backup.log"

# You can either backup all of the services (even those not in use)
# or you can specify which services you want to backup.

# Path to serveradmin command

serveradmincmd="/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin"

services=`$serveradmincmd list`
#services="afp ipfilter smb"

# This is the password you will use to recover your OD sparseimage.
# It should NOT be the same as your Directory Administrator password
# for security reasons.

passwd="<password>"

# Number of days worth of backups to keep

backupdays="30"

# This is the hostname of the server the script is running on
# This variable is used so that the same script can be run
# from multiple servers on a single share point
server=`hostname`

# Purge backups older than the amount of days user has set above

find "${recover_path}/$server/"* -maxdepth 0 -mtime +$backupdays -print | xargs rm

# Get today's date and format it as YYYYMMDD
date=`date ''+%c%m%d'' | awk '{printf $5}'`

# Set the full path to where this days backups will be stored
recover=${recover_path}/$server/$date

mkdir -p "${recover}"
chmod 600 "${recover}"

# grab the server configuration plists
for service in $services; do
    $serveradmincmd settings $service > "${recover}/$service.txt"
    sleep 1
done

# Backup Open Directory

/usr/bin/expect -c '
spawn slapconfig -backupdb "'"${recover}/_OD_Backup_${date}"'"
sleep 10
expect "Enter archive password:"
send "'"${passwd}\r"'"
expect "============"
' >${logfile}

echo "Script Complete at `date`" >>${logfile}
exit 0

NAME
nwfstime - Display / Set a NetWare server's date and time SYNOPSIS
nwfstime [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -s ] DESCRIPTION
nwfstime displays a NetWare server's date and time. You can also set a NetWare server's date and time from the local time. OPTIONS
-h With -h nwfstime prints a little help text. -S server is the name of the server you want to use. -U user user is the user name to use for login. To set the server's time, you need supervisor privileges. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwfstime prompts for a password. -n -n should be given if no password is required for the login. As you need supervisor privileges for setting the date and time, this option is probably not used very often. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. -s With -s, nwfstime sets the file server's date and time according to the local date and time. nwfstime 12/10/1996 NWFSTIME(1)
