Scripting code for sensitive users in Linux systems _linux Shell

A sensitive user here means that the user belongs to more than one group, or that the user belongs to a group name that is not the same as the user name.

#!  /bin/bash 
#list user who belong than one group 
#and list user who belong to the group which isn ' t the same As the username #w is whitelist,we would not do it 
whitelist is special or dangerous w= ("root" "ADM" gam Es "" Operator "" Halt "" Shutdown "" Sync "" Daemon "" Bin "" operator ") function WhiteList () 
{for- 
    I in ${w[@]} 
    do< c7/>if ["$i" = "$"];then return
            1 
        fi do return
    0 
} 
ifs= "for line in 
' Cat/etc/pa Sswd|awk-f: ' {print '} ' do
    WhiteList $LINE; 
    #if $? Equal 1,means It is in the whitelist     if [$-eq 0];then a=
        ' groups $LINE |awk-f: ' {print $} ' 
        b= ' echo $a ' 
        if ["$b"!= "$LINE"];then
            #echo $LINE             echo ' groups $LINE ' 
        fi
    fi done
