sed ' s/PAN/TAN/g ' <i/p> > <o/p>
sed ' s/^M/^M/g ' <i/p> > <o/p> (1st ^M is Ctrl+V+M, 2nd should be line feed/next line)
There are errors in the samples posted which would perhaps be more visible if the lines were posted in code tags.
1) There is no "output filename" parameter to "sed". See "man sed".
2) There are excess space characters in the commands posted.

Code:
First command should probably be:
sed -e "s/PAN/TAN/g" input_filename > output_filename

Second command.
I have never been able to make this conversion work with "sed".
Part of the problem is that "sed" does not recognise a line at all unless it ends with a line-feed character.
If you just want to convert carriage-return to line-feed, use the unix translate command "tr".

cat input_filename | tr '[\r]' '[\n]' > output_filename

Most of these carriage-return issues arise when a text file is created on a M$ platform and the copied to a
unix platform using a file transfer method which does not convert the file (e.g. binary mode ftp).
The normal repair involves running unix command "dos2unix" or "dos2ux" to convert the text file.
When foreign character sets are involved it can be better to convert the file with "tr" or an "awk" program.

NAME
shell - run a command using shell SYNOPSIS
shell command [command] ... DESCRIPTION
The shell function concatenate its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise /usr/bin/sh). EXAMPLES
Example 1: A sample output of shell command. Since the Form and Menu Language does not directly support background processing, the shell function can be used instead. `shell "build prog > /dev/null &"` If you want the user to continue to be able to interact with the application while the background job is running, the output of an exe- cutable run by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing. shell can also be used to execute a command that has the same name as an FMLI built-in function. NOTES
The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local environments will not be expanded by the shell because "local" means "local to the current process." ATTRIBUTES
