Advanced grep'in... grep for data next to static element.
I have a directory I need to grep which consists of numbered sub directories. The sub directory names change daily. A file resides in this main directory that shows which sub directories are FULL backups or INCREMENTAL backups.

My goal is to grep the directory for the word "full" and then preceding that word in the file is the name of the sub directory the FULL backup is in. So I then need to grab that name and execute a tar or cp command on that directory.

EXAMPLE: contents of the directory are: 123 124 125 126 file.txt file2.txt

In file.txt there is a line that reads: [backup 123 full type etc etc]
This tells me the FULL backup is in the 123 directory (the data right in front of the word FULL)

I then need to tar or cp the 123 directory.

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.
