date - Batch Code to Skip Script if File is too Old -


my problem

as there ton of threads address 'using batch file return file modify date' (or delete files older than, etc) - let me first specify issue.

i'm looking create batch (not powershell, etc) return last modify date of specific file given unc path , filename.

code, attempt 1

i've taken peek @ few potential solutions on other threads, i've run number of unique issues. first , obvious solution "forfiles" command in batch. example:

set mypath=\\myuncpath set myfile=myfilename.csv  forfiles /p "%mypath%" /m %myfile% /c "goto oldfile" /d -6

thus, if file older want -- jump specific section of batch that. however, yields error:

error: unc paths (\machine\share) not supported.

however, cmd won't work due use of unc (which critical batch called system's task scheduler). seems 'forfiles' cmd out.

code, attempt 2

i go more round way of doing it, retrieving last modified date of file (which in batch return string). can truncate string necessary date values, convert date, , compare current date. that, i've looked using loop such as:

set myfile=\\myuncpath\myfilename.csv echo %myfile% pause  %%f in (%myfile%) set myfiledate=%%~tf echo %myfiledate% pause

though first debug echo provides proper full file name, second debug returns echo off., tells me it's either not finding file or loop isn't returning file date. not sure why.

i've tried minor changes double check environmental variable syntax: 

for %%f in (%myfile%) set myfiledate=%%~ta

returns %ta

and finally:

for %%f in (%myfile%) set myfiledate=%~ta

which without '%', crashes batch.

i'm @ loss @ point. tips or guidance appreciated!

using forfiles unc path can used using pushd

for echoing file older x in unc path, use 

pushd %mypath% &&( forfiles -s -m %myfile% -d -6 -c "cmd /c echo /q @file   ) & popd

here 1 way how use goto if file older x found in unc path using examples. 

if not exist "c:\temp" mkdir c:\temp if not exist "c:\temp\test.txt" echo.>"c:\temp\test.txt" break>"c:\temp\test.txt"  set mypath=\\myuncpath set myfile=myfilename.csv  pushd %mypath% &&( forfiles -s -m %myfile% -d -6 -c "cmd /c echo /q @file >> c:\temp\test.txt"    ) & popd  /f %%i in ("c:\temp\test.txt") set size=%%~zi if %size% gtr 0 goto next  :next

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
