The vi utility is an interactive editor, not a scripting editor. Look at the man pages for ex, ed, and sed for utilities that are intended to be used to edit files in scripts.

What I want to do is just delete some lines from a text file, I know it's easy using copy and redirect function, but what I have to do is edit this file (delete the lines) directly, as new lines may be added to the text file during this period. Can AIX do this ?

NAME
ldbedit - Edit LDB databases using your preferred editor
SYNOPSIS
ldbedit [-?] [--usage] [-s base|one|sub] [-b basedn] [-a] [-e editor] [-H LDB-URL] [expression] [attributes...]
DESCRIPTION
ldbedit is a utility that allows you to edit LDB entries (in tdb files, sqlite files or LDAP servers) using your preferred editor. ldbedit
generates an LDIF file based on your query, allows you to edit the LDIF, and then merges that LDIF back into the LDB backend.
OPTIONS
-?, --help
Show list of available options, and a phrase describing what that option does.
--usage
Show list of available options. This is similar to the help option, however it does not provide any description, and is hence shorter.
-H <ldb-url>
LDB URL to connect to. For a tdb database, this will be of the form tdb://filename. For a LDAP connection over unix domain sockets,
this will be of the form ldapi://socket. For a (potentially remote) LDAP connection over TCP, this will be of the form ldap://hostname.
For an SQLite database, this will be of the form sqlite://filename.
-s one|sub|base
Search scope to use. One-level, subtree or base.
-a, -all
Edit all records. This allows you to apply the same change to a number of records at once. You probably want to combine this with an
expression of the form "objectclass=*".
-e editor, --editor editor
Specify the editor that should be used (overrides the VISUAL and EDITOR environment variables). If this option is not used, and neither
VISUAL nor EDITOR environment variables are set, then the vi editor will be used.
-b basedn
Specify Base Distinguished Name to use.
-v, --verbose
Make ldbedit more verbose about the operations that are being performed. Without this option, ldbedit will only provide a summary
change line.
ENVIRONMENT
LDB_URL
LDB URL to connect to. This can be overridden by using the -H command-line option.)
VISUAL and EDITOR
Environment variables used to determine what editor to use. VISUAL takes precedence over EDITOR, and both are overridden by the -e
command-line option.
VERSION
This man page is correct for version 4.0 of the Samba suite.
