How to use sed to insert character in the beginning of file path?
I need to manipulate one Database file on Solaris 11 in which contains more than 5000 lines of data file path like this:

Code:
 '/data1/oradata/DBNAME/system01.dbf',
  '/data7/oradata/DBNAME/undotbs1_01.dbf',
  '/data1/oradata/DBNAME/sysaux01.dbf',
  '/data28/oradata/DBNAME/userdata01.dbf',
  '/data28/oradata/DBNAME/user_data01.dbf',
  '/data128/oradata/DBNAME/undotbs1_02.dbf',
................................................
  '/datadw29/oradata/DBNAME/corp/comm_sd37.dbf',
  '/datadw28/oradata/DBNAME/corp/comm_sd38.dbf',
.................................................................................................
  '/dataidxdw42/oradata/DBNAME/ods/ODS_DATA_IDX_07.dbf',
  '/dataidxdw42/oradata/DBNAME/ods/ODS_DATA_IDX_08.dbf'

,

In these path lines, the first part of path name contains number '/data28/ and three path group with different first part of name. I need to insert one path name: "bck1" in the beginning of each path name. After manipulation, the path name in the file should be like this:

Code:
 '/bck1/data1/oradata/DBNAME/system01.dbf',
  '/bck1/data7/oradata/DBNAME/undotbs1_01.dbf',
  '/bck1/data1/oradata/DBNAME/sysaux01.dbf',
  '/bck1/data28/oradata/DBNAME/userdata01.dbf',
  '/bck1/data28/oradata/DBNAME/user_data01.dbf',
  '/bck1/data128/oradata/DBNAME/undotbs1_02.dbf',
................................................
  '/bck1/datadw29/oradata/DBNAME/corp/comm_sd37.dbf',
  '/bck1/datadw28/oradata/DBNAME/corp/comm_sd38.dbf',
.................................................................................................
  '/bck1/dataidxdw42/oradata/DBNAME/ods/ODS_DATA_IDX_07.dbf',
  '/bck1/dataidxdw42/oradata/DBNAME/ods/ODS_DATA_IDX_08.dbf'

I tried to use "v"i editor and "sed" to insert first part of path name. it can work on some lines and could not globally make change. I want to learn how to use "sed" to globally update the file path and deal with different number in path name and with different path name. Please help to provide your advice and command here. I will test and come back to report progress. Thanks for your time and help.

xbase::sdbm

XBase::SDBM(3)						User Contributed Perl Documentation					    XBase::SDBM(3)

NAME

       XBase::SDBM - SDBM index support for dbf

DESCRIPTION

       When developing the XBase.pm/DBD::XBase module, I was trying to support as many existing variants of file formats as possible. The module
       thus accepts wide range of dbf files and their versions from various producers. But with index files, the task is much, much harder. First,
       there is little or no documentation of index files formats, so the development is based on reverse engineering.

       None if the index formats support is finalized. That made it hard to integrate them into one consistent API. That is why I decided to write
       my own index support, and as I wanted to avoid inventing yet another way of storing records in pages and similar things, I used SDBM. It
       comes with Perl, so you already have it, and it's proven and it works.

       Now, SDBM is a module that aims at other task than to do supporting indexes for a dbf. But equality tests are fast with it and I have
       creted a structure in each index file to enable "walk" though the index file.
