Hi RudiC -


Here is what I arrived at with your help of the definitions in your last response.



The reason I"m using a for loop is so I can check what path is being passed in as certain files/directories have different retention requirements.


So, at the end of my script(s), I'd put this:


Code:
#::-- End of Processing - Purge & Logout  --::#
#::-- Add all paths in double quotes seperated by a space that should be purged --::#
#::-- PLEASE KEEP the outside set of double quotes as shown --::#
_DLIST=""${_INTRAPATH}" "${_ERRORINTRAPATH}""
Purge; Logout "0"

For this purpose ( & script) I only need to pass in the log and error directories since nothing major happens. However, for data integration scripts, data exports, the _DLIST variable would be inclusive of many more.



Then my function looks like such:


Code:
Purge () {

    for _DIR in $_DLIST; do _LD="$(basename "${_DIR}")";
        
        #::-- If basename directory is in YYYY_MMDD format, strip off all + 1 --::#
        if [[ $_LD == *"${_YEAR}_"* ]]; then _DIR="${_DIR::${#_DIR}-10}"; fi
        
        #::-- Directions: --::#
        #::-- Add relevant if statements using basename directory --::#
        #::-- Add value to _AGE variable indicating purge folder/files older than X days --::#
        #::-- If basename directory is in "YYYY_MMDD" format, use one folder up --::#
        #::-- If directory is "/u01/Cloud_Automation/Applications/APP/Files/PBCS_Reset_Service_Logs/2018_0615
        #     use "_Logs" [as long as it's unique - otherwise use full name] for filter in if statement --::#
        
        if [[ $_DIR == *"_Logs"* ]] || [[ $_DIR == *"_Errors"* ]]; then    _AGE="14"; fi
        
        #::-- [fail-safe] will only execute if _DIR & _AGE are defined --::#
        if [ -n "$_DIR" ] && [ -n "$_AGE" ]; then 
            find "$_DIR" -mtime +$_AGE -print0 | xargs -0 rm -rf
        fi
    done
}

As an example, for this purpose, the following to paths are passed in:


Code:
/home/oracle/Cloud_Automation/Applications/APPNAME/Logs/PBCS_Reset_Service_Logs/2018_0615
/home/oracle/Cloud_Automation/Applications/APPNAME/Errors/PBCS_Reset_Service_Errors/2018_0615

If the baseline folder is detected as YEAR_MONTHDAY format, I strip that off first before purging or else it wouldn't hit the other YEAR_MONTHDAY folders in the /PBCS_Reset_Service_*/ directory.



Let me know if I'm way off base here - thanks!

LEARN ABOUT DEBIAN

rmm

RMM(1)								     [nmh-1.5]								    RMM(1)

NAME

       rmm - remove messages

SYNOPSIS

       rmm [+folder] [msgs] [-unlink | -nounlink] [-version] [-help]

DESCRIPTION

       By  default,  rmm  will remove the specified messages by renaming each of the message files with a site-dependent prefix (usually a comma).
       Such files will then need to be removed in some manner after a certain amount of time.  Many sites arrange for cron to remove  these  files
       once a day, so check with your system administrator.

       Alternately,  if  you  wish  for  rmm to really remove the files representing these messages, you can use the -unlink switch.  But messages
       removed by this method cannot be later recovered.

       If you prefer a more sophisticated method of `removing' messages, you can define the rmmproc profile component.	For example, you can add a
       profile component such as

	    rmmproc:  /home/foouser/bin/rmm_msgs

       then instead of simply renaming the message file, rmm will call the named program or script to handle the files that represent the messages
       to be deleted.

       Some users of csh prefer the following:

	    alias rmm 'refile +d'

       where folder `+d' is a folder for deleted messages, and

	    alias mexp 'rm `mhpath +d all`'

       is used to "expunge" deleted messages.

       The current message is not changed by rmm, so a next
	will advance to the next message in the folder as expected.

FILES

       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS

       Path:		    To determine the user's nmh directory
       Current-Folder:	    To find the default current folder
       rmmproc: 	    Program to delete the message

SEE ALSO

       refile(1), rmf(1)

DEFAULTS

       `+folder' defaults to the current folder
       `msgs' defaults to cur
       `-nounlink'

CONTEXT

       If a folder is given, it will become the current folder.

BUGS

       Since refile uses your rmmproc to delete the message, the rmmproc must NOT call refile without specifying -normmproc, or you will create an
       infinte loop.
