Bash - re-ordering list of parameters
Hello.

I have a script that writes parameters in alphabetic order.
But I have a parameter which have 3 lines. There is no continuation character ( '\' ). Each of the three lines finish with 'cr'. But line 2 and 3 of the concerning parameter start with a tab char (but should be one or more space).
Code:
.............
.............
.............
debugger_command =
     PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
     ddd $daemon_directory/$process_name $process_id & sleep 5
.............
.............
.............

When my script finished, I got this :
Code:
content_filter =
daemon_directory = /usr/lib/postfix
data_directory = /var/lib/postfix
     ddd $daemon_directory/$process_name $process_id & sleep 5
debugger_command =
debug_peer_level = 2
default_transport = error:outside mail is not deliverable
defer_transports =
.............
.............
.............
.............
     PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
.............
.............

The position of the 3 red lines are arbitrary.

Now I would like now to re-read the result file and modify it to obtain this :
Code:
content_filter =
daemon_directory = /usr/lib/postfix
data_directory = /var/lib/postfix
debugger_command =
     ddd $daemon_directory/$process_name $process_id & sleep 5
     PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
debug_peer_level = 2
default_transport = error:outside mail is not deliverable
defer_transports =
.............
 .............
.............

Any help is welcome.

getusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

       /bin/bash		  /bin/csh
       /bin/jsh 		  /bin/ksh
       /bin/pfcsh		  /bin/pfksh
       /bin/pfsh		  /bin/sh
       /bin/tcsh		  /bin/zsh
       /sbin/jsh		  /sbin/pfsh
       /sbin/sh 		  /usr/bin/bash
       /usr/bin/csh		  /usr/bin/jsh
       /usr/bin/ksh		  /usr/bin/pfcsh
       /usr/bin/pfksh		  /usr/bin/pfsh
       /usr/bin/sh		  /usr/bin/tcsh
       /usr/bin/zsh		  /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
