Top Forums Shell Programming and Scripting How to insert text within a file? Post 302947482 by RudiC on Thursday 18th of June 2015 08:49:37 AM

Given this script called, say, list_days
Code:
#!/bin/bash

MDarr=(0 31 28 31 30 31 30 31 31 30 31 30 31)
function mthdays() { printf "%d\n" $((MDarr[$1] + (M!=2?0:!($2%4) && ($2%100) || !($2%400)))); }

IFS=- read Year Month  Day SecEpoch R <<< $(date -d"$1" +%F-%s)

seq 0 $(($(mthdays $Month $Year) - Day )) |  while read TMP; do printf "%(%F)T\n" $((SecEpoch + 86401 * TMP)); done

(which, admittedly, takes advantage of some recent bash features that don't necessarily exits in other shells),
Code:
./list_days 2015-6-18 | sort -u - dates

should do what you requested: print the porous list that you gave and fills in the holes from the start date (parameter 1) till EOMonth. While the mthdays function should be leap year proof, I added the 1 sec in the loop to make it leap second proof. On second thought, as this usually happens on the last day of a month, it will not be relevant...

Date::Manip::ConfigFile(3pm)				User Contributed Perl Documentation			      Date::Manip::ConfigFile(3pm)

NAME
Date::Manip::ConfigFile - sample config file DESCRIPTION
Date::Manip is a highly configurable module. Many of the options can be set in a config file. This document includes a sample config file. The config file consists of three sections. The first section is config variables. This is described more fully in the Date::Manip::Config document. The second section is the holiday definition section. The third section is the event definition section. These are both described more fully in the Date::Manip::Holidays document. SAMPLE CONFIG FILE
The sample config file below works for newer versions of Date::Manip. Some of the config variables may change, or be deprecated, and some may not work with earlier versions of Date::Manip, so it is strongly suggested that you check out the documentation for the version of Date::Manip you are using to confirm any of the config variables you want to include. ################################ # CONFIG VARIABLES ################################ # See Date::Manip::Config man page for a description of all # config variables. # To include configuration information from additional # config files: ConfigFile = /path/to/another/config/file ConfigFile = /path/to/another/config/file2 # For handling other languages Language = English DateFormat = US Encoding = # Set the current timezone: SetDate = now,America/New_York # Set the work work WorkWeekBeg = 1 WorkWeekEnd = 5 WorkDay24Hr = 0 WorkDayBeg = 08:00 WorkDayEnd = 17:00 TomorrowFirst = 1 # Misc. variables YYtoYYYY = 89 FirstDay = 1 Jan1Week1 = 0 Printable = 0 DefaultTime = midnight RecurRange = none ################################ # HOLIDAYS ################################ # See the Date::Manip::Holidays man page for a description of # this section. *HOLIDAYS # FEDERAL HOLIDAYS ################## # You can express New Year's Day as the actual day (Jan 1) # or the observed day (Jan 1 or the nearest week day). # You can't include BOTH because once a day is marked as # a holiday, a second definition will treat it the same # as a weekend and choose another day to assign the holiday # to (so there would be two days designated as New Years). # Jan 1 = New Year's Day 1*1:0:1:0:0:0*DWD = New Year's Day (observed) # Two different ways to defined MLK day third Monday in Jan = Martin Luther King Jr.'s Birthday # 1*1:3:1:0:0:0 = Martin Luther King Jr.'s Birthday # Observed by federal employees in Washington D.C. # Jan 20 = Inauguration day third Monday in Feb = Washington's Birthday last Monday in May = Memorial Day 1st Monday in Sep = Labor Day second Monday in Oct = Columbus Day # Jul 4 = Independence Day 1*7:0:4:0:0:0*DWD = Independence Day # 11/11 = Veterans Day 1*11:0:11:0:0:0*DWD = Veteran's Day # To define both Thanksgiving and the day after, use the # following two lines: fourth Thu in Nov = Thanksgiving 1*11:4:4:0:0:0*FD1 = Day after Thanksgiving # Dec 25 = Christmas 1*12:0:25:0:0:0*DWD = Christmas # SAMPLE HOLIDAYS ################## # You can define a one-time-only holiday by specifying # the day and year. 6/2/1999 = A special test holiday for 1999 ################################ # EVENTS ################################ # See the Date::Manip::Holidays man page for a description of # this section. *EVENTS 2000-02-01 = Event01 2000-02-01-12:00:00 = Event02 02-01 = Event03 02-01 12:00:00 = Event04 1*2:0:3:13:00:00 = Event05 2000-02-05 10:00:00 ; 2000-02-05 10:59:59 = Event06 2000-02-05 ; 2000-02-06 = Event07 02-05 ; 02-06 = Event08 2000-02-07 10:00:00 ; 0:0:0:0:3:0:0 = Event09 02-07 10:00:00 ; 0:0:0:0:4:0:0 = Event10 1*2:0:7:10:00:00 ; 0:0:0:0:5:0:0 = Event11 SEE ALSO
