Search and replace with awk
Hi Shell Tigers,
I am trying to acheive search and replace strings within a setup file.
Help much appreciated.

Code:
  test.setup
    ORACLE_HOME=/oracle/product/11.0.0/home01
    PATH1=/perm_loc/3222/FTP/cfg1
    PATH2=/perm_loc/3222/FTP/cfg2/bin
    PATH3=/perm_loc/3222/FTP/cfg3/bin

So far I have tried
Code:
  cat test.setup | awk -F= -v a="MonsterHouse.Scully" -v b="Mickey/Minie" '{if ($1 == "ORACLE_HOME" ) printf "ORACLE_HOME=%s\n",a;
  else if ( $2 ~ /perm_loc/ ) print (gsub("perm_loc",b)); else print;}'

I get the following results
test.setup
Code:
 ORACLE_HOME=MonsterHouse.Scully 
 1
 1 
 1

Expected :
test.setup
Code:
    test.setup
    ORACLE_HOME=MonsterHouse.Scully
    PATH1=/Mickey/Minie/3222/FTP/cfg1
    PATH2=/Mickey/Minie/3222/FTP/cfg2/bin
    PATH3=/Mickey/Minie/3222/FTP/cfg3/bin

FTPUSERS(5)						     Linux Programmer's Manual						       FTPUSERS(5)

NAME

       ftpusers - list of users that may not log in via the FTP daemon

DESCRIPTION

       The  text  file	ftpusers  contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon.  This file is
       used not merely for system administration purposes but for improving security within a TCP/IP networked	environment.   It  will  typically
       contain	a  list  of  the  users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP
       server daemon.  Such users usually include root, daemon, bin, uucp, and news.  If your FTP server daemon doesn't use ftpusers  then  it	is
       suggested  that	you  read  its	documentation  to find out how to block access for certain users.  Washington University FTP server Daemon
       (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers.

   Format
       The format of ftpusers is very simple.  There is one account name (or username) per line.  Lines starting with a # are ignored.

FILES

       /etc/ftpusers

SEE ALSO

       passwd(5), proftpd(8), wuftpd(8)
