expression - bash variable evaluating with quote for special character -

-

below simple bash script test few password in rar file. when password contains special character (!), see option (-p) parsed quote ('). 

#!/bin/bash -x  pwd=`echo sei{0..9}{0..9}b{0..9}axq!zx` #pwd=sei03b4axq!zx file="test.rar" eachpwd in $pwd     eval unrar x "$file" -p"$eachpwd" id 2>/dev/null 1>/dev/null     c=$?     if [ $c = 0 ]         echo "success"         exit     fi     echo $eachpwd $c done

output 

+ eachpwd in '$pwd' + eval unrar x test.rar '-psei49b4axq!zx' id + c=10 + '[' 10 = 0 ']' + echo 'sei49b4axq!zx' 10

question
how code such that, during eval not unrar x test.rar '-psei49b4axq!zx' id instead unrar x test.rar -psei49b4axq!zx id evaluated expression

update 1
tried below code, still quote(!) on -p option refuses budge. 

passwords=( sei{0..9}{0..9}b{0..9}axq!zx ) file=test.rar  password in "${passwords[@]}";     if unrar x "$file" -p"$password" id 2>/dev/null 1>/dev/null;         echo "success"         exit     else         echo $password failed.     fi done

result 

   + password in '"${passwords[@]}"'     + unrar x test.rar '-psei21b0axq!zx' id     + echo 'sei21b0axq!zx' failed.     sei21b0axq!zx failed.     + password in '"${passwords[@]}"'     + unrar x test.rar '-psei21b1axq!zx' id

please note using bash shell execution.

there couple of possible explanations happening, none of worth exploring because don't need use eval. also, it's better use array hold passwords, or put brace expression directly in for loop, rather creating single string.

# use single quotes on small chance history expansion # enabled, protect !. can drop them. passwords=( sei{0..9}{0..9}b{0..9}'axq!zx' )  password in "${passwords[@]}";     if unrar x "$file" -p "$eachpwd" id 2>/dev/null 1>/dev/null;         echo "success"         exit     fi done

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...
