Code:
mkdir -p /home/admin/useraccounts
for (( i=0; i<=500; i++ )) 
do
        #Create users whose name starts with baci, 
        #so this script will create baci1, baci2, baci3 etc depending on i value.   
   useradd baci$i
   < /dev/urandom tr -dc A-Na-n1-9_ |\
   head -c8 > /tmp/passwd.txt
        #this command is bit tricky, < /dev/urandom  
        #will generate all the random characters which are not even present
        #on keyboard.. and tr -dc A-Na-n1-9, will display only characters
        #which are from A to N, a to n and 1 to 9. This is to avoide o(small o),  
        #O(capital o), 0(numerical zero) characters in order to remove 
        #confusion in the password.  #And there is no character limit.   so head -c8
        #will limit the random characters to just 8
 
done   # was missing!!!  (VBE)

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
atf-sh(3) BSD
