help with multiple loops in shell script
Hi Guys-

I'm trying to write a script which takes date as input (mm.yy.dd) and search in the current file. If pattern doesn't exist it will then look in a backup directory and so on.

being a newb i'm unable to loop over to the backup directory. hoping for some ideas, i've highlighted the area where i'm stuck . any advice is appreciated.
I have about mutiple backup directories in the root_dir and the script should keep searching until it runs out of directories.

the naming convention of backup directories is backup-yyyy.mm.dd


Code:
#!bin/bash

datetime=$1
root_dir=/home/xyz
bkup_dir=`ls -tr | grep -i "backup-" | tail -1
pattern=`grep "$datetime" $root_dir/logfile

if [ $pattern = "" ]
then "go into bkup folder and search for pattern "
else
   echo -e $pattern
fi

nisbackup

nisbackup(1M)                                             System Administration Commands                                             nisbackup(1M)

NAME

       nisbackup - backup NIS+ directories

SYNOPSIS

       nisbackup [-v] backup-dir directory...

       nisbackup [-v] -a backup-dir

DESCRIPTION

       nisbackup  backs  up a NIS+ directory object on a NIS+ master server. Updates to the NIS+ database will be temporarily disabled while  nis-
       backup is running.  The  backup-dir is a UNIX directory that must exist prior to running  nisbackup. The  nisbackup command can be used  to
       backup  an  individual  NIS+  directory  object  or  all ( -a) of the NIS+ directory objects served by a master server.  The NIS+ directory
       objects being backed up will be placed into subdirectories under the  backup-dir directory.  These subdirectories are  named  according  to
       the  NIS+  directory  object  they contain.  nisbackup operates on individual NIS+ directory objects  (for example,  org_dir.wiz.com). This
       allows an administrator to selectively backup specific directories.

       The  rpc.nisd(1M) process must be running on the master server with a stable NIS+ database for  nisbackup to complete. nisbackup  will  not
       attempt  to  correct any corruption in the NIS+ database, so it is important that backups be done regularly as part of the NIS+ administra-
       tion.

       The first synopsis is used to backup a single NIS+ directory object or a list of NIS+ directory objects. The objects can be partially qual-
       ified or fully qualified. The machine on which the command is executing must be the master for the NIS+ directory objects specified.

       The  second synopsis will backup all of the NIS+ directory objects that are served by this master. The  -a option is the recommended method
       of backing up a master server,  since it will backup all NIS+ directory objects that are served by  this master. If this server is a master
       server for more than one domain, the backup will include NIS+ directories that belong to all of the domains served.  Individual NIS+ direc-
       tory objects can be selected for restoring from a  backup-dir created with the  -a option. See  nisrestore(1M).

       The  -a option only includes directory objects for which this server is the master. It is possible, but not  recommended,  to  configure  a
       master  server as a replica for other domains. The objects belonging to those replicated domains will not be backed up with the  -a option.
       The backup of replicated objects must be run on the master server for those objects.

       Do not use the same  backup-dir to backup different master servers. Each master server must have its own  backup-dir.

       nisbackup will set the  rpc.nisd(1M) to read only mode, which will disable updates to the NIS+ database.  This is neccessary to ensure  the
       consistency of the backup.  For this reason, nisbackup should not be run while large numbers of updates are being applied to the NIS+ data-
       base. Update utilities such as  nisaddent(1M) should not be run simultaneously with nisbackup.

OPTIONS

       -a       Creates a backup of all NIS+ directory objects for which this server is a  master.

       -v       Verbose option. Additional output will be produced and sent to syslog(3C) upon execution of the command (see  syslog.conf(4)).

OPERANDS

       backup-dir      The directory into which the subdirectories containing the backed up objects  are placed. This must  be  created  prior  to
                       running  nisbackup.

       directory       The NIS+ directory object(s) being backed up.

EXAMPLES

       Example 1: Backup of the  org_dir NIS+ directory object of the domain  foo.com on a master server to a directory named  /backup

       To backup the  org_dir NIS+ directory object of the domain  foo.com on a master server to a directory named  /backup:

       master_server# nisbackup /backup org_dir.foo.com.

       Example 2: Backup of the entire NIS+ domain  foo.com to a directory named  /backup

       To backup the entire NIS+ domain  foo.com to a directory named  /backup:

       master_server# nisbackup /backup foo.com. 
                     org_dir.foo.com. groups_dir.foo.com. 
                     ctx_dir.foo.com.

       Example 3: Backup of an entire NIS+ database to a backup directory named /backup

       To backup an entire NIS+ database to a backup directory named /backup:

       master_server# nisbackup -a /backup

EXIT STATUS

       0        Successful completion.

       1        An error occurred.
