convert fixed length file to CSV
Newbie

Looking for a script to convert my input file to delimited text file. Not familier with AWK or shell programing. Below is sample record in my input file and the expected output format. My OS is HPUX 11.23.

Thanks in advance for your assistance.

input file:

Question Am I reading your sample right?
It looks like each of the first three records will have slightly different rules.
(1) has 1230-1630 as field
(2) does not have this field
(3) creates this field by splitting off the previous field

rec (4) appears like rec (2)
# 3  
Old 08-06-2008
Yes, that is correct the rules will be different. How do you set the delimiter(,) if there is nothing in the field(ie field 11 of record 2,3 and 4?

1230-1630 is a field. Basically REC1 is the master record format.

Question Maybe let's talk this through for rules before going further
There are three possible record layouts. So, read the record.
if five fields separated by " " space characters, then type A
if four fields and field 3 is 17 characters, then type B
if four fields and field 3 is 23 characters, then type C (similar to type A)

Is this correct logic?

Old 08-06-2008
Can you use perl? If so, you can build a mask for each of the three fixed format records, then unpack() them and join() them using your delimiter (looks like a space, supposed to be comma in CSV??)....

$mycsv = join(" ", unpack("mask-goes-here"));
