The construction "&&" is used for immediate execution after the first process ends. In fact it is a logical "AND", which connects the two processes and the second one is executed if the first ends with return code "0" (zero).

Ending with return code "0" is commonly the sign of "normal end of operation", whereas everything abnormal should produce an exit code different to "0".

This seems to be the correct implementation for you, because the first process creates files which the second one uses. Perhaps, if the first aborts somehow abnormally the file won't be there and the second one should not start in this case.

For your second problem, to wait some time, there is the "sleep" command: it takes a number of seconds as parameter and waits for this time.

Code:
command1
sleep 3000         # 60 secs * 50
command2

should do the trick.

I hope this helps.

update-metainit

UPDATE-METAINIT(1)					User Contributed Perl Documentation					UPDATE-METAINIT(1)

NAME

       update-metainit - Generates init scripts

SYNOPSIS

       update-metainit [--remove initname [--purge] ]

DESCRIPTION

       Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a
       declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis-
       trator.

       If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain
       a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made
       effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment.

OPTIONS

       --remove initname
	   This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname.

       --purge
	   Only usable with --remove. Will remove the generated files even if modified.
