UNIX for Dummies Questions & Answers

Hi
I have two files
File 1
alias HOME =..
alias DATA = ${DATA}/runtime1/test
alias SQL = ${DATA}/find1dir/test
alias SQL1 = ${HOME}/sql/orcl
alias SQL2 = ${HOME}/sql2/orcl
alias SQL3 = ${HOME}/sql3/orcl

File2
alias HOME = ..
alias DATA = ${DATA}/runtime/test
alias SQL = ${DATA}/finddir/test
alias SQL1 = ${HOME}/sql/orcl
alias Serv = ${DATA}/catdir/test
i am capturing "alias HOME" like that stuff in the left hand side of = of file1 in a variable that is $param
and greping it in file2 . i am not bothered about the value in the right hand side
i am only concerned about the additional params in file1 that is not in file 2
Also i am not concerned about the additional params in file2
but the grep is not working as required
Some parameters it is working and not for other parameters
It works fine outside the shell script in the console but not in shell script

/usr/xpg4/bin/grep -i "$param" File2 > /dev/null 2>&1
I have even tried
grep -i "$param" File2 > /dev/null 2>&1

Code:

awk  -F'='  ' FILENAME=="file2" { arr[$1]++}
                 FILENAME=="file1" { if (! $1 in arr) {print $1} }' file2 file1

Thanks for your reply but I am sorry but i did get a syntax error i am not knowing where i am going wrong
if i try the statement in one line it says
awk: illegal statement near line 1
awk: syntax error near line 1
awk: bailing out near line 1


if i try printing in two lines it says
awk: illegal statement near line 2
awk: syntax error near line 2
awk: bailing out near line 2

Thanks
