linux - KSH password generator -

how make sure generated passwords contains these special characters (?!/=) ?

currently i'm using:

pwd_usr["$i"]=`cat /dev/urandom|tr -dc "a-za-z0-9-_\?\!\=\/\"|fold -w 15|head -n 1` 

but of generated passwords might not contain special characters want. please help. thanks.

i suggest manually can check out yourself, so:

i=0 while -lt 100     i=$(expr + 1)     var=$(pwd_usr["$i"]=`cat /dev/urandom|tr -dc "a-za-z0-9-_\?\!\=\/\"|fold -w 15|head -n 1`) done echo $var 

so this, create 100 passwords, store them in var , output of echo can check if passwords contain want, , happy or keep on working :)

p.s

to make easier yourself, after output gets printed copy of editor , use search, control+f, know, , add characters want in order save lots of time.
