Generate a list of the newest file in each subdirectory in windows batch -

-

i have need determine newest file in each subdirectory under root folder , output list text file showing both filename , creation date. example, if root directory d:\data contains total of 4 subdirectories, , 1 of 4 contain subdirectory, output file should contain list of files (not including created folders) this:

d:\data\folder1\filename 02/12/14

d:\data\folder2\filename 03/02/14

d:\data\folder3\filename 03/15/14

d:\data\folder4\folder01\filename 01/22/14

i have checked other posts, none seem specifically...

two options

@echo off     setlocal enableextensions enabledelayedexpansion      set "rootfolder=c:\somewhere"  :: option 1     echo --------------------------------------------------------------------------------     /d /r "%rootfolder%" %%a in (.) (         set "first="         /f "delims=" %%b in ('dir /o-d /a-d /b "%%~fa\*" 2^>nul') if not defined first (             set "first=1"             %%c in ("%%~fa\%%b") echo %%~tc %%~fc         )     )  :: option 2     echo --------------------------------------------------------------------------------     set "tempfile=%temp%\%~nx0.%random%.tmp"     dir /a-d /b /s /o-d "%rootfolder%" 2>nul >"%tempfile%"      set "oldfolder="     /f "usebackq delims=" %%a in ("%tempfile%") if not "%%~dpa"=="!oldfolder!" (         echo %%~ta %%~fa         set "oldfolder=%%~dpa"     )      del /q "%tempfile%" >nul 2>nul

option 1 recurse on folders structure , each one, dir command executed retrieve list of files in folder in descending date order. first in list rececent one.

option 2 use 1 dir command retrieve full list of files in descending date order , save retrieved information in temporary file. file processed. each time name of folder changes, output first line recent file in folder.

option 1 start earlier echo information, multiple commands used, require more time execute, needs less memory retrieve file list of 1 folder each time.

option 2 uses less commands , faster, uses temporary file , requires more memory option 1 full file list loaded in memory.

select depending of how deep folder structure, how files have, how memory, .... test.

C# random value from dictionary and tuple -

i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
