The second suggestion, using tr(1) to 'delete' the \015 character is
easy to wrap in a script that does this automagically for you. In
fact, a script that puts together the right tools to do your job is
probably the best way to do this. You can filter all the files that
match '^M' with a combination of find, grep and other standard FreeBSD
tools.
Hell you can even make an ex(1) script and do the equivalent
of `editing the file' in a non-interactive way.
Here's a sample session from a test I just did to convert a file
called "hello.txt" from DOS format to Unix format.
> cat -e hello.txt
hello world^M$
> cat ~/scripts/dos2unix.ex
%s/^M/g
:wq
> ex -c ":so dos2unix.ex" hello.txt
hello.txt: 1 lines, 1 characters
> cat -e hello.txt
hello world$

Since `editing' a file to remove ^M characters can be done with ex(1)
and our simple dos2unix.ex script, and you have saved dos2unix.ex in
your HOME/scripts directory (haven't you?) here's a command line that
will convert all the *.txt files under ~/doc to Unix format:
> find ~/doc -name '*.txt' |\
xargs -1 ex -c ":so $HOME/scripts/dos2unix.ex"
And that's just one of a billion ways to do this. You can probably
find easier and faster ways, or tools that will do everything you want
without all this `scripting madness'.
