Using multiple gsub() function under a loop in awk
Hi ALL,

I want to replace string occurrence in my file "Config" using a external file named "Mapping" using awk.

$cat Config
! Configuration file for RAVI
! Configuration file for RACHANA
! Configuration file for BALLU


$cat Mapping
ravi:ram
rachana:shyam
ballu:hameed

The expected output after running the awk script should be

! Configuration file for RAM
! Configuration file for SHYAM
! Configuration file for HAMMEED

For the out expected out I used awk as below.

Code:
$ awk ' {FS=":"} FNR==NR { array[$1]=$2; next  }  {FS=" "} FNR!=NR 
{ for (i in array)  IGNORECASE = 1 gsub("Configuration file for "i, "Configuration file for " array[i])    }1
'   Mapping   Config

And the output is coming as expected.
But when I use two gsub() functions (other one for an additional replacement)
one with IGNORECASE = 0 and other with IGNORECASE = 1. my second gsub("Configuration file for "i, "Configuration file for " array[i]) function is not working as expected.

Code:
$ awk ' {FS=":"} FNR==NR { array[$1]=$2; next  }  {FS=" "} FNR!=NR 
{ for (i in array)  gsub("^"i, array[i])   IGNORECASE = 1 gsub("Configuration file for "i, "Configuration file for " array[i])  }1
'   Mapping   Config


Can any one help me to know how to use two gsub() function under a for loop with first gsub() case sensitive and second one case insensitive search. Can any one help me improving the above code ?

Thanks in advance.....

LEARN ABOUT HPUX

ugweb

ugweb(1M)																 ugweb(1M)

NAME

       ugweb - starts the HP-UX User and Group Account Configuration tool

SYNOPSIS

       [ ] [ ]

DESCRIPTION

       The  HP-UX  User and Group Account Configuration tool ( ) is used to manage user accounts and group accounts on the local system. This tool
       can also be used to manage user accounts on a NIS system.

       The HP-UX User and Group Account Configuration tool provides both Web-based  and  terminal  user  interface.  The  Web-based  interface	is
       launched through the HP System Management Homepage.

       Superuser  privileges are required to access the HP-UX User and Group Account Configuration tool. A user who does not have superuser privi-
       leges has read-only access to the Local Users, NIS Users and Groups areas in the HP-UX User and Group Account Configuration tool and cannot
       modify local user accounts, group accounts and NIS User accounts.

       An  attempt  will be made to connect to a Mozilla/Netscape Web browser running on the X server defined by the DISPLAY environment variable.
       If a running Mozilla/Netscape client is found, it will be used, otherwise a new Mozilla/Netscape session will be initiated. This will  only
       happen  if  the	Mozilla/Netscape process is running in the same system as that referenced by the DISPLAY variable, unless the -F option is
       used.

       Note: By default, the HP-UX User and Group Account Configuration tool (ugweb) invokes the Mozilla Web browser. If you want to  support  any
       other browser (Netscape), set the $BROWSER environment variable as shown below:

       The terminal user interface is invoked if any of the following conditions are true:

	      o  The command is invoked with the option.

	      o  The environment variable is not set.

       The Web-based interface is launched if all the following conditions are true:

	      o  The command is invoked with option.

	      o  The environment variable is set.

	      o  The command is available on the system.

       If the Web-based interface cannot be launched, invokes the terminal user interface.

   Options
       recognizes the following options:

	      Forces a client browser to be used in less secure ways.

			The  option  forces the client browser to be used or started, even when the X-traffic between the X-server and the Mozilla
			browser is not secure.

			Use this option only when you are sure the network traffic between the host where Mozilla is running and the host  in  the
			DISPLAY variable is secure.

			If cannot start the Web browser, the terminal interface is started.

			When the HP-UX User and Group Account Configuration Web interface is invoked by SMH, the option is used.

	      If a privileged user (root) executes the
			command  with  the  option,  a	temporary login bypass key is generated. The bypass key enables the user to access the Web
			interface without having to provide login information again.

			When the HP-UX User and Group Account Configuration interface is started by SMH, the option is used.

	      Launches the terminal interface for managing local users, NIS users and groups regardless of the current setting of the
			environment variable.

       You can also start the HP-UX User and Group Account Configuration tool using one of the following methods:

	      o  Run and select the Accounts for Users and Groups to launch the tool in Terminal User Interface mode

	      o  Start the HP-UX User and Group Account Configuration tool Web interface by typing the URL in the address  bar	of  your  browser,
		 where hostname is the name of the server

	      o  Launch  the HP-UX Systems Insight Manager on the server and select the User and Group Account Configuration tool from the Config-
		 ure -> HP-UX Configuration menu

Online Help
       After the HP-UX User and Group Account Configuration tool is started, the online help provides details on how to use the tool.

RETURN VALUES

       Upon completion, ugweb returns one of the following values:

	      o  0    Successful

	      o  1    An error occurred
