dos - Passing exclamation marks as parameters in batch subroutine call -

-

thanks community have learned how escape exlamation marks immediate use in batch delayedexpansion block. (use 2 escape carets not one, awesome)

but can't seem find or figure out how pass contents of variable containing exclamation mark parameter batch subroutine.

example:

@echo off setlocal enabledelayedexpansion set variable=hello^^! echo "!variable!" call :subroutine "!variable:^^!=^^!!" pause exit  :subroutine echo "%~1" exit/b

output:

"hello!" "hello" press key continue . . .

i want second "hello" include exclamation mark. have tried various permutations of substring replacement on line 5 no avail.

help

you need different way variable replacing, , more carets.

@echo off setlocal enabledelayedexpansion set variable=hello^^! echo "!variable!" call :subroutine %variable:!=^^^^^^^^^^!% exit /b  :subroutine echo %~1 exit /b

or quotes: call :subroutine "%variable:!=^^^!%"

in function need expand %1 without quotes, number of carets odd in call parameter.

but @ it's bad idea try such things.
agree aacini, should use pass reference instead.
way handle any possible content.

@echo off setlocal enabledelayedexpansion set variable=hello^^! echo "!variable!" call :subroutine variable exit /b  :subroutine echo !%1! exit /b

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...
