Apologies, my bad. I should've uploaded the file. Attached is a masked .dat file renamed as .txt for uploading.
On opening it with notepad++ in Windows, the null characters show up as boxes. In a Linux vi the nulls are ^@.
All the records in this file are in one row. This particular file has 2 records followed by the trailer record.
First record = starts at the beginning of the file 00000230 (this field gives the length of the record in bytes)
Second record = starts at the next 00000230 (it is a coincidence, here both records have same length)
Trailer record = starts at 0000096 (the trailer length is of 96 bytes and it also has 80 delimiters of ^@ or null characters. Ignore my earlier post saying trailer has 20 delimiters. It has 80 actually)
As the field lengths are variable so we cannot define a record in terms of total length of its fields or total bytes. This is why we are defining a record as effectively having length of 80 ^@ delimiters.
I require the 1st record in one row, 2nd record in next row and so on till the end of the file, with the trailer in the last row. If there is a way of adding a newline after every 80th ^@ from the beginning till the eof, then perhaps it will work?
The only unprintable character is null ^@, no TABS or other spaces, all other characters are alphanumeric.
Please let me know if any questions. Thanks for the help
Hi,
I need add leading zeroes to a field in a file based on the character count. The field can be of 1 character to 6 character length. I need to make the field 14bytes.
eg:
8351,20,1
8351,234,6
8351,2,0
8351,1234,2
8351,123456,1
8351,12345,2
This should become.

mdb-tables
MDBTools(1)MDBTools(1)NAME
mdb-tables - Get listing of tables in an MDB database
SYNOPSIS
mdb-tables [-S] [-1 | -d delimiter] database
DESCRIPTION
mdb-tables is a utility program distributed with MDB Tools.
It produces a list of tables contained within an MDB database in a format suitable for use in shell scripts.
OPTIONS -S Show system tables. System tables are generally those beginning with 'MSys'
-1 specifies that the tables should be listed 1 per line.
-d delimiter
specifies an alternative delimiter. If no delimiter is specified, table names will be delimited by a tab character, or by newline if
the -1 option was specified.
NOTES ENVIRONMENT
MDB_JET3_CHARSET
Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1).
MDBICONV
Defines the output charset. Default is UTF-8. mdbtools must have been compiled with iconv.
MDBOPTS
semi-column separated list of options:
o use_index
o no_memo
o debug_like
o debug_write
o debug_usage
o debug_ole
o debug_row
o debug_props
o debug_all is a shortcut for all debug_* options
HISTORY
mdb-tables first appeared in MDB Tools 0.3.
SEE ALSO gmdb2(1)mdb-export(1)mdb-hexdump(1)mdb-prop(1)mdb-sql(1)mdb-ver(1)mdb-array(1)mdb-header(1)mdb-parsecsv(1)mdb-schema(1)AUTHORS
The mdb-tables utility was written by Brian Bruns.
BUGS
Access allows for tables to have spaces embeded in the table name.
You must specify a delimiter (-d) if you intend on piping the output of mdb-tables to a program such as awk or cut.
