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

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
