Search and Replace in Perl

I am trying to write a simple perl script to run on a FreeBSD machine.
There are alot of posts here, and I have read so many, yet can not get this script to run.
Code:
#!/usr/bin/perl

-e 's/\r\n/~/' infile.txt outfile.txt

I am trying to take a windows text file, move it into Unix, run a script on it.
For starters, I only want this to replace the first carriage return/line feed with a ~
I do not want to convert it to Unix, just replace the first carriage return/line feed.
I have tried \r\n and also \015\012
The file is an ASCII text file, created in notepad.

I am getting errors about the \ and the /, therefore I also tried:
Code:
#!/usr/bin/perl

-e 's:\r\n:~:' infile.txt outfile.txt

Yet no luck. It also seams to tell me it is looking for a operator before the infile.txt Also get Can't locate object method "txt" via package "outfile"
another error message:
Code:
Bareword found where operator expected at ./xyz.pl line 2, near "'s:\r\n:~:' infile.txt"

(Missing operator before infile?)


Any ideas?

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
