How to remove the ^M characters in a file on FreeBSD?
This is simple:
There are multiple ways to do it. One is actually included in the FreeBSD-tips file:
— Originally by Dru
So if you installed the “games” distribution, you get tips every time you log in. And once in a while the above tip will show up.
I had never used that one however, I had always used this one (which I modified) that I found here: http://sed.sourceforge.net/sed1line.txt
However, this one works with the sh, tcsh and bash but not with the csh shell.
This one worked on csh but I am not sure if it is recommended as it assumes every line ends with ^M.
Anyway, I like how FreeBSD supports the -i parameter. Because if I am doing lots of files, I can have a script that does each file in a directory and then (of course I have a back up just in case) I can run sed -i.bak ‘s/.$//’ filename on each file and then do delete all .bak files so every file “appears to be” edited in place.
Your penning method is pleasing and also the way you managed the topic with grace is commdneable. I am intrigued, I presume you are an professional on this subject. I just sign up for your RSS feed.
For vi editor users: `:% s/^M//g`, (note: to get `^M` use ^V + ^M combination, where `^` is the Ctrl key).
