Creating a script
Alright, well I did some more research since I originally posted this thread, and as much as I'd like to delete it, I can't, so I'll just extend my initial question a little.

Right now I have 3 scripts:
1
Code:
#!/bin/bash
# script1 - Write all files modfied x days ago
find  ..  -daystart -mtime 0 -type f | xargs ls -sSh > data_170611

2
Code:
#!/bin/bash
# script2 - Write all files modified x days ago and remove leading spaces
find  ..  -daystart -mtime 0 -type f | xargs ls -sSh > data_170611
sed 's/^ *//' data_170611 > data_170611_1

3
Code:
#!/bin/bash
# script3 - Write all files modified x days ago, remove leading spaces and write changes to two lists
find .. -daystart -mtime 0 -type f | xargs ls -sSh > data_170611
sed 's/^ *//' data_170611 > data_170611_1
find  ..  -daystart -mtime 0 -type f | xargs ls -sSh > data_200611
sed 's/^ *//' data_200611 > data_200611_1
awk '{if(FNR==NR) {arr[$0]++;next} if($0 in arr) { arr[$0]--; if (arr[$0] == 0) delete arr[$0];next}{print $0 >"FYes"}} END {for(i in arr){print i >"FTod"}}' data_200611_1 data_170611_1

Each new one is obviously just an extension of the old one. FYes and FTod are just my abbreviations for "Flagged Today" and "Flagged Yesterday" as there are two output files.

I have a few questions people may be able to answer:
1. The files that i named data_170611 and data_200611 are just files of data that refer to a date.
Ideally I would like to somehow get the script to grab that date and add it after data_ so I don't have to manually edit my script each day.
EDIT
Using
Code:
DATE=`date +%d%m%y`

I now have todays date ^.^
Also found what I consider a 'weird' way of formatting that date to show 1 day prior...
Code:
DDMMYY=`date --date='1 day ago' +%d%m%y`

2. My sed command requires me to write to a new file, is there a way to just overwrite it? I have tried just using data_170611 > data_170611 but that results in a blank file.

any ideas?

locale::codes::langfam

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
