VI questions : mass changes, mass delete and external insert
Is it possible in VI to do a global change but take the search patterns and the replacement patterns from an external file ?
I have cases where I can have 100,200 or 300+ global changes to do. All the new records are inside a file and I must VI a work file to change all of them.
Also, can I do a mass delete on records given by an external file no matter where those records are in VI ?
And insert content of a whole file at any given point in VI ?
I do not think I have autority to replace or recreate the files I am editing at the office. Only the search pattern files I can create as I like.

NAME
fwtmp, wtmpfix - manipulate connect accounting records
SYNOPSIS
[files]
DESCRIPTION
fwtmp
reads from the standard input and writes to the standard output, converting binary records of the type found in to formatted ASCII records.
The ASCII version is useful to enable editing, via ed(1), bad records or for general purpose maintenance of the file.
The argument is used to denote that input is in ASCII form, and output is to be written in binary form. The arguments and are independent,
respectively specifying ASCII input and binary output. Therefor, is an ASCII to ASCII copy and is a binary to binary copy. should be used
for reading If is not used, structure is read.
wtmpfix
examines the standard input or named files in format, corrects the time/date stamps to make the entries consistent, and writes to the stan-
dard output. A can be used in place of files to indicate the standard input. If time/date corrections are not performed, will fault when
it encounters certain date-change records.
Each time the date is set, a pair of date change records is written to The first record is the old date denoted by the string old time
placed in the line field and the flag placed in the type field of the structure. The second record specifies the new date, and is denoted
by the string placed in the line field and the flag placed in the type field. uses these records to synchronize all time stamps in the
file. nullifies date change records when writing to the standard output by setting the time field of the structure in the old date change
record equal to the time field in the new date change record. This prevents and from factoring in a date change record pair more than
once.
In addition to correcting time/date stamps, wtmpfix checks the validity of the name field to ensure that it consists solely of alphanumeric
characters or spaces. If it encounters a name that is considered invalid, it changes the login name to and writes a diagnostic to the
standard error. This minimizes the risk that will fail when processing connect accounting records.
DIAGNOSTICS
wtmpfix generates the following diagnostics messages:
WARNINGS
generates no errors, even on garbage input.
