UNIX command to ignore replacing a search string if it is already present
Hello,
I am searching the following string Folder^ in a file and replacing it with Folder^/
However if the file already contains Folder^/ I want to avoid replacing it with Folder^//
To do this I have to do the following today:
1) echo "Folder^" | sed 's/Folder\^/Folder\^\//g'
I get "Folder^/"
2) echo "Folder^/" | sed 's/Folder\^/Folder\^\//g'
I get "Folder^//"
Is there a way in awk or sed to do this a single command. I know I can do the following - but I am looking for a more smarter way to do this
1) replace Folder^/ by Folder^
2) replace Folder^ by Folder^/

mail::filter5.18
Mail::Filter(3) User Contributed Perl Documentation Mail::Filter(3)NAME
Mail::Filter - Filter mail through multiple subroutines
SYNOPSIS
use Mail::Filter;
my $filter = Mail::Filter->new( &filter1, &filter2 );
my $mail = Mail::Internet->new( [<>] );
my $mail = $filter->filter($mail);
my $folder = Mail::Folder->new( .... );
my $filter->filter($folder);
DESCRIPTION
"Mail::Filter" provides an interface to filtering Email through multiple subroutines.
"Mail::Filter" filters mail by calling each filter subroutine in turn. Each filter subroutine is called with two arguments, the first is
the filter object and the second is the mail or folder object being filtered.
The result from each filter sub is passed to the next filter as the mail object. If a filter subroutine returns undef, then "Mail::Filter"
will abort and return immediately.
The function returns the result from the last subroutine to operate on the mail object.
METHODS
Constructors
Mail::Filter->new([FILTER [, ... ]])
Create a new "Mail::Filter" object with the given filter subroutines. Each filter may be either a code reference or the name of a
method to call on the <Mail::Filter> object.
Accessors
$obj->add(FILTER [, FILTER ...])
Add the given filters to the end of the filter list.
Processing
$obj->filter(MAIL-OBJECT | MAIL-FOLDER)
If the first argument is a "Mail::Internet" object, then this object will be passed through the filter list. If the first argument is a
"Mail::Folder" object, then each message in turn will be passed through the filter list.
$obj->folder()
While the "filter" method is called with a "Mail::Folder" object, these filter subroutines can call this method to obtain the folder
object that is being processed.
$obj->msgnum()
If the "filter" method is called with a "Mail::Folder" object, then the filter subroutines may call this method to obtain the message
number of the message that is being processed.
