Top Forums Shell Programming and Scripting How to split a fixed width text file into several ones based on a column value? Post 302482360 by bhanja_trinanja on Tuesday 21st of December 2010 09:54:03 AM

Sample file attached

Ok... here is a sample.

The first field is Date in YYYYMMDD.

As you can see, there are 3 dates viz. 20100313, 20100306 and 20100227.

The length of the Date field is 8 bytes.

I want my shell script to read this file and create 3 files, each with data for each of the 3 dates.

Thanks in advance. Smilie

Code:
20100313  25     2899780446536301 0   1    9.99
20100313  22     9819780446541930 0   1    6.99

NAME
dm_zdump - timezone dumper SYNOPSIS
This performs the same operation as the unix 'zdump' command, but using the Date::Manip module. dm_zdump [-v] [-c YEAR] [ZONE ZONE ...] DESCRIPTION
This displays the current time in each ZONE named on the command line unless the -v option is given. -h, --help Print online help. -v, --verbose This displays all critical dates (i.e. the times when a time change occurs due to the timezone description) for each of the timezones listed (or the local timezone if none are listed). Each critical date is printed as two lines of output: the last second before the change occurs, and the first second of the new time. By default, all critical dates from Jan 1, 0001 until the year 20 years in the future are printed, but this can be changed with the -c option. -c, --cutoff YEAR This specifies the cutoff year. All critical dates up to the start of YEAR are given. The GMT time Jan 01, YEAR at 00:00:00 is the cutoff time. KNOWN BUGS
None known. BUGS AND QUESTIONS
