Logical OR using sed
Hello,

This must be a novice question to you folks. But I searched through various places and did not find an answer to this question:

How do we perform a logical OR operation using sed command? For example, I want to write a command that extracts all the text between pattern1 and pattern2 OR pattern3. I tried using the below command, and it didn't work:
sed -n '/pattern1,pattern2|pattern3/'p <file_name>

Please advice me in case any of you have a solution.

Thanks,
Thejasvi V

sbdadm

sbdadm(1M)						  System Administration Commands						sbdadm(1M)

NAME

       sbdadm - SCSI Block Disk command line interface

SYNOPSIS

       sbdadm create-lu [-s, --size size] filename

       sbdadm delete-lu lu_name

       sbdadm import-lu lu_name

       sbdadm list-lu lu_name

       sbdadm modify-lu [-s, --size size] lu_name | filename

DESCRIPTION

       The  sbdadm  command  creates  and  manages  SCSI-block-device-based  logical units that are registered with the SCSI Target Mode Framework
       (STMF).

SUB-COMMANDS
       The sbdadm command supports the subcommands listed below. Note that if you enter a question mark as an argument to the command (sbdadm  ?),
       sbdadm responds with a help display.

       create-lu [-s, --size size] filename

	   Create a logical unit that can be registered with the STMF. For the -s option, size is an integer followed by one of the following let-
	   ters, to indicate a unit of size:

	   k	kilobyte

	   m	megabyte

	   g	gigabyte

	   t	terabyte

	   p	petabyte

	   e	exabyte

	   If you do not specify size, the size defaults to the size of filename.

	   The size specified can exceed the size of the file or device.

       delete-lu lu_name

	   Deletes an existing logical unit that was created using sbdadm create-lu. This effectively unloads  the  logical  unit  from  the  STMF
	   framework. Any existing data on the logical unit remains intact.

       import-lu lu_name

	   Imports  and  loads a logical unit into the STMF that was previously created using sbdadm create-lu and was since deleted from the STMF
	   using sbdadm delete-lu. On success, the logical unit is again made available to the STMF. filename is the filename used in  the  sbdadm
	   create-lu command for this logical unit.

       list-lu

	   List all logical units that were created using the sbdadm create-lu command.

       modify-lu [-s, --size size] lu_name | filename

	   Modifies attributes of an logical unit created using the sbdadm create-lu command. For the -s option, size is an integer value followed
	   by a unit specifier. The unit specifiers are as described above under create-lu. When this option is specified, the	existing  size	of
	   the logical unit is changed to the new size.

	   The size specified can exceed the size of the file or device represented by lu_name.

OPERANDS

       sbdadm use the following operands:

       filename

	   Name of an existing file or a fully qualified path to a raw block device.

       lu_name

	   The 32-byte hexadecimal representation of the logical unit.

EXAMPLES

       Example 1 Creating a Logical Unit

       The following series of commands creates a 10-gigabyte logical unit.

	 # touch /export/lun/0
	 # sbdadm create-lu -s 10g /export/lun/0
	 # sbdadm create-lu /dev/rdsk/c1t1d0s0

       Example 2 Listing Logical Units

       The following command lists all logical units.

	 # sbdadm list-lu
	 Found 2 LU(s)

			GUID		       DATA SIZE    SOURCE
	 --------------------------------  -----------	------
	 6000ae4000144f21d92c47b0dd650002  10737352704	/export/lun/0
	 6000ae4000144f21d92c47b0de300032  134283264	/dev/rdsk/c1t1d0s0

EXIT STATUS

       0

	   Successful completion.

       non-zero

	   An error occurred.
