Thanks, reborg, for you quick reply,

I think I wasn't clear enough.

This is the code I wrote:

Code:
#!/bin/sh
HOME=/home/mvo
PATH=/home/mvo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

echo -------------------------------------------- >> /home/mvo/backuplog
echo Backup Started `date` >> /home/mvo/backuplog
cd /

if [ -d /home/backups/`date +%w`/ ] ; then
   rm /home/backups/`date +%w`/backup.tar.gz
   echo Overwriting Day `date +%w` starting now.. >> /home/mvo/backuplog
else
   mkdir /home/backups/`date +%w`/
fi

mkdir /home/backups/tmp
mysqldump -u Username -pPassword Databasename | gzip > /home/backups/tmp/mysqldump.sql.dump.gz
echo Database Backup Complete.. >> /home/mvo/backuplog

cp -Rf /var/www /home/backups/tmp
cp -Rf /home/groupoffice /home/backups/tmp
tar czvf /home/backups/`date +%w`/backup.tar.gz /home/backups/tmp
rm -Rf /home/backups/tmp
echo GroupOffice Backup Complete.. >> /home/mvo/backuplog

echo Backup Completed `date` >> /home/mvo/backuplog

And it is a cronjob. However when I run this script ./backup.sh then everything works fine.. When I run it through a cronjob the "rm -Rf /home/backups/tmp" and the "cp -Rf /var/www /home/backups/tmp" commands are like "overwritten" by the next commands.. in other words: they start to early aka they wont wait for previous command to finish.

How can I get past this? I've tried sleep but I want to keep my script flexibel as the content of the backupdirs may change in size.
So what I want to do is wait for a command to finish before calling a next command!

Thanks for you help!

cpanplus::shell

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.

       Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
