Top Forums Shell Programming and Scripting Linux shell script to insert new lines based on delimiter count Post 302986013 by digitalnirvana on Friday 18th of November 2016 08:12:49 AM

Does that code start splitting from 480th position i.e. 6th record and work backwards? Apologies for the stupid question but where is it matching the delimiter?

The file can be of any length, ie have any number of records. The records in the file are also of variable length so the only way to identify the end of a record is that it is after each 81st occurrence of the "^@" delimiter.

Ie from the start of the file till 81st delimiter is one record, 82nd till 163rd is the second record, and so on.

The records are currently all in one line and they need to be in multiple lines ie separated by \n

Is there a way to do the 81st delimiter check till end of file

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. 0.7 13 July 2013 MDBTools(1)
