Well we've reached post #10 and we know that the file is over 7Gb and you want to edit it. We know nothing about the file itself, but other posters have suggested unix text file editing techniques. Is it a unix text format file with manageable record length?

Have you edited similar (but smaller) files in the same format? If so, what did you do?

Please post what Operating System and version you have.
Please describe the process or program which wrote this file (mentioning programming language or database engine if relevant).

CDBS-EDIT-PATCH(1)						CDBS Documentation						CDBS-EDIT-PATCH(1)

NAME

       cdbs-edit-patch - create or edit a CDBS simple-patchsys.mk patch

SYNOPSIS

       cdbs-edit-patch patchname

DESCRIPTION

       cdbs-edit-patch	creates  or edits patches for use by the CDBS simple-patchsys.mk patch system.	For more information about CDBS please see
       the documentation under /usr/share/doc/cdbs/.

       When patchname exists, cdbs-edit-patch will set up a temporary working source tree, apply all patches up to and including patchname in lex-
       icographic  order,  and	spawn  an  interactive shell for the developer.  The developer can then edit files in this working tree.  When the
       developer is done and exits the shell, cdbs-edit-patch updates patchname to reflect the changes made.  To abort the process from the inter-
       active shell, exit with a nonzero exit value.

       When patchname does not exist, cdbs-edit-patch will assume that a new patch should be created.  As with the above scenario, cdbs-edit-patch
       will first create a temporary working source tree and apply all patches up to the new patch in lexicographic  order.   When  the  shell	is
       quit, cdbs-edit-patch will create patchname.
