I am writing a script to run a series of perl-scripts/system commands, but I want to make sure that if something goes wrong nothing else happens. Is die the best way of going about this, or do you think there should be some form of error handling instead?

chdir("$staging_directory")
    or die "Could not change directory to $staging_directory: $!\n";
system("svn", "update", "base")
    or die "Could not svn update base: $!\n";
system("svn", "update", "hostgroup")
    or die "Could not svn update hostgroup: $!\n";
system("svn", "update", "host")
    or die "Could not svn update host: $!\n";
system("$copier_program_location", "$staging_directory", "$pre_launch_
+directory", "$copier_conf_file")
    or die "Could not run copier $copier_program_location: $!\n";
system("$permissions_program_location", "-c", "$permissions_conf_file"
+)
    or die "Could not run permissions program $permissions_program_loc
+ation: $!\n";
system("rsync", "-avz", "--exclude=.svn", "--delete-after", "$pre_laun
+ch_directory", "$live_directory")
    or die "Could not perform rsync from $pre_launch_directory to $liv
+e_directory: $!\n";

On a side note, are system() calls the best way to call other perl scripts, or would some kind of use or sub better form? (The $blah_program_location above are perl scripts)

Thanks in advance.
