Use of sed inside perl
Code:
$string="test.binary.value";
$toggle="test.binary.value=true";
host=test.server.com

my $returnCode = system ( "ssh $host 'cp -p /tmp/testfile /tmp/testfile.bkup; sed -i 's/\$string.*/\$toggle/g' /tmp/testfile'" );

cat testfile

test.binary.value=false

Scenario: I am trying to change the value of that binary to true from false. The user provides $toggle as an argument to the perl script. I want to change the line what ever be the previous line in the file to what user entered. Its like search and replace.

The above is my code but its not working, but its simply making the file empty/null. I am not sure whats the mistake I am making. Any help would be greatly appreciated.

ipptool

ipptool(1)							    Apple Inc.								ipptool(1)

NAME

       ipptool - perform internet printing protocol requests

SYNOPSIS

       ipptool [ -4 ] [ -6 ] [ -C ] [ -E ] [ -I ] [ -L ] [ -S ] [ -T seconds ] [ -V version ] [ -X ] [ -c ] [ -d name=value ] [ -f filename ] [ -i
       seconds ] [ -n repeat-count ] [ -q ] [ -t ] [ -v ] URI filename [ ... filenameN ]

DESCRIPTION

       ipptool sends IPP requests to the specified URI and tests and/or displays the results. Each  named  file  defines  one  or  more  requests,
       including  the  expected  response status, attributes, and values. Output is either a plain text, formatted text, CSV, or XML report on the
       standard output, with a non-zero exit status indicating that one or more tests have failed. The file format is described in ipptoolfile(5).

OPTIONS

       The following options are recognized by ipptool:

       -4   Specifies that ipptool must connect to the printer or server using IPv4.

       -6   Specifies that ipptool must connect to the printer or server using IPv6.

       -C   Specifies that requests should be sent using the HTTP/1.1 "Transfer-Encoding: chunked" header, which is required  for  conformance	by
	    all  versions  of  IPP.  The default is to use "Transfer-Encoding: chunked" for requests with attached files and "Content-Length:" for
	    requests without attached files.

       -E   Forces TLS encryption when connecting to the server using the HTTP "Upgrade" header.

       -I   Specifies that ipptool will continue past errors.

       -L   Specifies that requests should be sent using the HTTP/1.0 "Content-Length:" header, which is required for conformance by all  versions
	    of IPP. The default is to use "Transfer-Encoding: chunked" for requests with attached files and "Content-Length:" for requests without
	    attached files.

       -S   Forces (dedicated) SSL encryption when connecting to the server.

       -T seconds
	    Specifies a timeout for IPP requests in seconds.

       -V version
	    Specifies the default IPP version to use: 1.0, 1.1, 2.0, 2.1, or 2.2. If not specified, version 1.1 is used.

       -X   Specifies that XML (Apple plist) output is desired instead of the plain text report. This option is incompatible with the  -i  (inter-
	    val) and -n (repeat-count) options.

       -c   Specifies that CSV (comma-separated values) output is desired instead of the plain text output.

       -d name=value
	    Defines the named variable.

       -f filename
	    Defines the default request filename for tests.

       -i seconds
	    Specifies  that  the (last) file should be repeated at the specified interval. This option is incompatible with the -X (XML plist out-
	    put) option.

       -l   Specifies that plain text output is desired.

       -n repeat-count
	    Specifies that the (last) file should be repeated the specified number of times. This option is incompatible with the  -X  (XML  plist
	    output) option.

       -t   Specifies that CUPS test report output is desired instead of the plain text output.

       -v   Specifies that all request and response attributes should be output in CUPS test mode (-t). This is the default for XML output.

COMPATIBILITY

       The ipptool program is unique to CUPS.
