As no samples are available, I have to guess there is something special with the input file. Did you test the suggestions with a simplified (abbreviated) dummy input file, possibly created copying a section of the original? Please post a (small but representative) hexdump of the input. Should look like
Code:
od -tx1c file
0000000 23 65 6d 70 6e 6f 0a 65 6e 61 6d 65 0a 6a 6f 62
# e m p n o \n e n a m e \n j o b

Hi Guys,
I have an awk script that would search the input file for line that starts with a number 3 and copies into a new text file.
I want to extend this script to find the lines that either starts with 3 or a or b and copy all those lines into the new file.
Here is what I have so far:... (1 Reply)

queue-repair
queue-repair(8) System Manager's Manual queue-repair(8)NAME
queue-repair - deal with the qmail queue directory structure
SYNOPSIS
queue-repair [ -htrcbn ] [ -n split ] [ conf-qmail ]
DESCRIPTION
queue-repair deals with the qmail queue structure; it can create a new queue, move and properly rename a queue, dynamically change the
conf-split value, convert big-todo queues to non-big-todo and vice versa, and repair a corrupted queue.
conf-qmail defaults to /var/lib/qmail/ on Debian.
OPTIONS
-h|--help
Display usage information and built-in defaults, then exit.
-t|--test
Run in test-only mode. queue-repair will attempt to report all problems that it finds, without correcting them. This is the
default.
-r|--repair
Run in repair mode. queue-repair will attempt to correct all problems that it finds, except if the basic queue directories (queue,
queue/mess, queue/info, etc) are not found.
-c|--create
Run in create-and-repair mode. queue-repair will attempt to correct all problems that it finds, including creation of a new queue
structure from scratch.
-s|--split split
Specify split as the value of conf-split. This is the number of split subdirectories for those queue directories which are hashed.
The default for qmail is 23. Appropriate values depend on the volume of mail handled, OS filesystem efficiency, and other factors,
but this should always be a prime number.
If you do not specify conf-split, queue-repair will attempt to determine the current value from the existing queue. This option can
be used, however, to change the conf-split value of an existing queue (qmail will still have to be recompiled with the new value).
When creating a new queue, this option must always be specified.
-b|--bigtoto
Use big-todo. queue-repair should be able to automatically determine if you're using qmail patched with the big-todo patch. This
option can be used, however, to convert a non-big-todo queue to a big-todo queue (qmail will still have to be recompiled with the
big-todo patch).
If neither this option nor --no-bigtodo is used, queue-repair will attempt to determine this automatically. When creating a new
queue, either this option or --no-bigtodo must always be specified.
-n|--no-bigtodo
Do not use big-todo. queue-repair should be able to automatically determine if you're using qmail patched with the big-todo patch.
This option can be used, however, to convert a big-todo queue to a non big-todo queue (qmail will still have to be recompiled with-
out the big-todo patch).
If neither this option nor --bigtodo is used, queue-repair will attempt to determine this automatically. When creating a new queue,
either this option or --bigtodo must always be specified.
--i-want-a-broken-conf-split
Force the use of a non-prime value for conf-split.
