Scripting mount, log gathering, verifying and unmounting


I am trying to piece together some scripts that I've started and some that I've gotten from someone here and modified for my use. I've messed around a bit but 'm not very good at the if then when do. I am getting to do cronjobs for the scripts at intervals but if there is a way to piece this into one script. What I'm trying to do on a weekly basis is.
Any advice would be appreciated.

- Mount a partition to a windows share
- check to see if mounted if mounted do the log gathering
- Gather, tar and zip audit logs and data files and move to the mount point
- remove logs once they are backed up
- remove mapping

The scripts do run individualy so I know they work. The scripts I have are;

Check if mapped if not than map
----------------------------
#!/usr/bin/perl
print `date`;

$ismounted = `df -h |awk '{ print $1 }'|grep ShareName`;

chomp ($ismounted)

unless ($ismounted =~ /ShareName/) {

print "/mnt/dump is NOT mounted!\n";

print "Mounting /mnt/dump...\n";
/opt/temp/scripts/xxxx_dumpsharedcmd_conv.exp`;
} else {
print "/mnt/dump is already mounted.\n";
exit;
}

-----------------------------------------------------
This is the mapping script called in the script above
-----------------------------------------------------

#xxxx_dumpsharecmd_conv.exp
#!/usr/bin/expect

set timeout 20

#set password xxxxxxxxxxx

spawn mount -t cifs //xxx.xxx.xxx.xxx/ShareName/Hostname /mnt/dump -o username=xxxxxx,credentials=dump_cred,iocharset=utf8
,file_mode=0777,dir_mode=0777

#expect "Password:"
#send "$password\r"

expect eof

---------------------------------------------------------------------
This script gathers the logs and data and puts them (for now in a temp dir called /opt/backup but it will be /mnt/dump
--------------------------------------------------------------------

#Logs_Data_Backup

#!/bin/sh
# Logs and Data Backup Script
# This script backups up all of the data to the /opt/backup directory.
# The Administrator will still be required to move this file to
# external media to enable bare-metal restoration of the system.
#
yyyy=`date "+%Y"`
mm=`date "+%m"`
dd=`date "+%d"`
Month=`date "+%b"`
Day=`date "+%e"`
dstr=`date "+%Y%m%d"`

mkdir /opt/backup/Hostname_logs_${dstr}
mkdir /opt/backup/Hostname_data_${dstr}
#
# Log section
#
/bin/tar --create --verbose --preserve \
--ignore-failed-read --gzip -- file=/opt/backup/Hostname_logs_${dstr}/Hostname_logfiles_${dstr}.tgz \
`cat /opt/temp/scripts/backup_dirs-log.txt | xargs` \
>> /opt/backup/Hostname_logs_${dstr}/Hostname_log_filelist.txt
#
# Data section
#
/bin/tar --create --verbose --preserve \
--ignore-failed-read --gzip --file=/opt/backup/Hostname_data_${dstr}/Hostname_datafiles_${dstr}.tgz \
`cat /opt/temp/scripts/backup_dirs-data.txt | xargs` \
>> /opt/backup/Hostname_data_${dstr}/Hostname_data_filelist.txt

echo "Backup complete on " `date` \
>> /backup/filelist.txt

------------------------------------------------------------
This script deletes the logs (this will be the /var/log/audit and /var/log), it's /opt/temp/logs for testing.
This should clean the zipped files out so the next time this runs there will be another weeks worth of accumulated zipped log files to backup.
--------------------------------------------------------------
#delete_backedup_logs*

#!/bin/bash
find /opt/temp/logs/*.gz -exec rm {} \;

You're using three different scripting languages. You use Perl for the first one, expect for the second, and sh/bash for the last two. The first thing you need to do is decide which one you want to use in your single script and then translate the others. After that, what specifically are you having problems with?

The other option is to write a single script that calls these four in the proper order.

Thanks. The scripts work individually so tying them together is the issue I have comprehending. Picking one scripting language and translating them sounds like fun so the idea of making one script and calling the other script files has crossed my mind. What I'm not sure about is how to tie them together and what to do if somewhere along the way one fails to run.
