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?

audit_warn

AUDIT_WARN(5)						      BSD File Formats Manual						     AUDIT_WARN(5)

NAME

     audit_warn -- alert when audit daemon issues warnings

DESCRIPTION

     The audit_warn script runs when auditd(8) generates warning messages.

     The default audit_warn is a script whose first parameter is the type of warning; the script appends its arguments to
     /etc/security/audit_messages.  Administrators may replace this script: a more comprehensive one would take different actions based on the
     type of warning.  For example, a low-space warning could result in an email message being sent to the administrator.

FILES

     /etc/security/audit_warn
     /etc/security/audit_messages

SEE ALSO

     audit(4), auditd(8)

HISTORY

     The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer Inc. in
     2004.  It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.

AUTHORS

     This software was created by McAfee Research, the security research division of McAfee, Inc., under contract to Apple Computer Inc.  Addi-
     tional authors include Wayne Salamon, Robert Watson, and SPARTA Inc.
