Bash Scripting with date format conversion

I have a script below and wanted to change the output into three different file format (3 separate script)

Code:
#!bin/bash
#input file format postwrf_d01_20131206_0600_f08400.grb2
#postwrf_d01_YYYYMMDD_ZZZZ_f0HHHH.grb2
#zzzz= 0000,0600,1200,1800 (in UTC)
#HHHH=00000,00600,01200,01800 ..ect (in hours)

for i in postwrf_d01_*_??00_f?????.grb2; do ./wgrib2 $i -match ':((U|V)GRD:10 m above ground|PRMSL|(ABSV|HGT):(850|700) mb)|((UGRD|VGRD) 850|700|500) mb):' -grib `basename -s .gr2 $i`_subset.grb2; done

I wanted to change the current output file format to

1. d01_YYYYMMDD_ZZZZ_f0HHHH.grb2
2. YYYYMMDD_ZZZZ_f0HHHH.gr2
3. nwp.TC23.YYYYMMDDZZ.f0MMMM
# for 3, hours is converted to minutes such that 0HHHH became 0MMMM
Y = year
M= month
D = Day
Z= initialization (0000,0600,1200,1800)
M= minutes (i.e 00000,00360, 00720 etc...)

NAME
holidays - prime/nonprime table for the accounting system SYNOPSIS
/etc/acct/holidays DESCRIPTION
The /etc/acct/holidays file describes which hours are considered prime time and which days are holidays. Holidays and weekends are con- sidered non-prime time hours. /etc/acct/holidays is used by the accounting system. All lines beginning with an "*" are comments. The /etc/acct/holidays file consists of two sections. The first non-comment line defines the current year and the start time of prime and non-prime time hours, in the form: current_year prime_start non_prime_start The remaining non-comment lines define the holidays in the form: month/day company_holiday Of these two fields, only the month/day is actually used by the accounting system programs. The /etc/acct/holidays file must be updated each year. EXAMPLES
Example 1: Example of the /etc/acct/holidays file. The following is an example of the /etc/acct/holidays file: * Prime/Nonprime Table for the accounting system * * Curr Prime Non-Prime * Year Start Start * 1991 0830 1800 * * only the first column (month/day) is significant. * * month/day Company Holiday * 1/1 New Years Day 5/30 Memorial Day 7/4 Indep.
