ipdelque

ipdelque

This program deletes files from a queue. This can be a single shot (default) or
you can specify a delay which the program will wait before restarting ad
infinitum.

Normally a 30 second wait is applied before the program starts in case the
wrong queue etc has been selected.

Optionally only files that are older (ie last time modified) than a certain
number of days or minutes can be deleted. This can be changed to checking
creation time by input switch -c.

For queues that accept networked files, a file creep time can be set.

IPDELQUE is often used in the nightly maintenance script ZAPFIPLOG to trim
holding queues and sundry save areas.

Strings in data can be searched and files deleted or NOT accordingly using the
-g/-G switch (plus -s for case sensitivity if necessary).
    eg: ipdelque -q yuko -g "txtclass=edito*"
will delete files containing txtclass=edito* in /fip/spool/yuko.
    (Note the * is NOT a wild card here so we have quoted the string)

Filenames can be checked too with -k or -K.
    eg: ipdelque -q zibbo -K ttt
will delete all files in zibbo EXCEPT those with '.ttt' somewhere in the name

Input parameters are :
    Mandatory :
    -q : input queue name               default: none
        This can be a full pathname starting '/'
        or a relative to current path if starting '.' as in './xyz'
        otherwise it is assumed to be a queue under /fip/spool.
    Optional :
    -a : age subqueues in this queue        default: no
        syntax is -a 8 for eight days worth
        - move any files in the queue to a new subqueue called
(queue)/(queue).CCYYMMDD
        - if the subparameter > 0, zap any subqueues older than that number of days
    -A : age subqueues and files in this queue  default: no
        Syntax is -A 3 for deleting all queues over 3 days old
        This variation is for queues that begin YYMMDD or YYYYMMDD
            eg  970925-reuters
                20001231-31223-SPORTS
        All files or queues older than the date the program is run (minus the
subparameter) are deleted.
        Any files or queues whose name does not start with a date are ignored.
    -l : log all deleted files
        default: normally only one QUEUE DELETED msg appears
    -L : do NOT log if no files were deleted    default: (as above)
    -m : delete files if more than x days only  default: all files
        This deletes all files up to midnight before the day.
    -M : delete files if more than x mins only  default: all files
    -c : check time of creation         default: last modify
    -C : check file name                default: no checking beforehand
        only zap files if this checkfile exists
        This is to check that UNC, NAS and other remote drives are actually
mounted/accessible beore deleting
    -d : WINNT only drive letter for queue  default: drive Fip started on
    -E : add ExtraFipHdr information        default: none
    -f : file wait                  default: 0
        (ie wait x secs for file to finish before processing)
    -g : search string in data - if present,    default: all files
        delete THIS file but NOT those without it.
    -G : search string in data - if present,    default: all files
        do NOT delete THIS file but delete those without it.
    -h : for search string in data, ignore the FipHdr. default: all data
    -i : wait in secs before starting to delete default: wait 30 secs
        -i 10   wait 10 seconds beforehand
        -i 0    do NOT wait before deleting
        If the '-t' switch (spooling) is also on, this wait is
        applied to the FIRST scan only, after which it is ignored.
    -k : filename mask - if present,        default: all files
        delete THIS file but NOT those without it.
    -K : filename mask - if present,        default: all files
        do NOT delete THIS file but delete those without it.
    -OLD : for -a make the aged queue YYMMDD not CCYYMMDD
    -Q : DO NOT create the folder if it does not exist  default: create
    -r : delete any Mac Resource forks in ./.rsrc   default: no
    -R : Run ONLY if the server is Primary      default: always process
        Only the primary host actually does the delete  default: delete
        Eg if there is an entry in the tables/sys/DEST_REDUN file :
            nassvr  fip-l01v-p  fip-l02v-p
        and you run ipdelque -R nassvr -q /uncdrive/somefolder/subq/
        then fip-l02v-p will only run the delete if fip-l01v-p is down
        This can be used run to zap on shared drives in conjunction with -C (chkfile)
from only one of the Fips
        (Use -S if you want to run on the Secondary(ies) only)
    -s : search string is case SENSitive        default: case insens.
    -S : Run ONLY if the server is Secondary (ie opposite of -R)    default: always
process
    -t : sleep between scans of the directory.  default: run once only
        The minimum scan time is 10 seconds -t 10
    -T : do NOT delete any files starting with a dot    default: delete
    -X : just display filename that should be zapped (ver 08k+ only) def: delete
    -v : version no and exit

From version 08k onwards there is also a -X input switch which displays the
files that would be deleted - BUT does not delete ! All previous version just
zap !
