Take ^M's out of files

[Coolmar]

Hi,

I downloaded some source code that I have to compile. It is for unix, but was created with a .zip extension. Therefore, when I unzip it to unix - every file is full of ^Ms. Does anyone know of a quick way to remove them from all the files in the directory? Or is there a way that with winzip I can extract the files without all the ^M's?

The standard command is the dos2ux, but to do a lot of them perl works best...

perl -n -i -e 'chomp; print $_,"\n"' *.txt

Will replace them for all .txt files.

cat filename | sed -e "s/[ctrl-v ctrl-m]//" > newfilename

by [ctrl-v ctrl-m] I mean you should hit ctrl-v then ctrl-m between the first and second "/" (slash).

Oh, I forgot - another way (if you're on HPUX) is just run "dos2ux oldfilename > newfilename".

Or how about using the vi editor since you probably have it open in vi anyway. Use the global search and replace:

:%s/^M//g

now to get that you have to type CTL-V and CTL-M but it will look like the example. When you hit CTL-V it will put the ^ symbol then the CTL-M will put the Cap M. To read the command, inside of vi:

%s is search / search-string / replace-string / g globally..

It will replace all ^M with null.

Thanks for all the suggestions....I have used dos2ux...however, there are about 120 files...I was just hoping there would be a faster way rather than one by one.

That's what scripts are for. Who in their right mind would invoke dos2ux 120 times interactively?

Extracted the files to my desktop and then ftp'd them to the unix system using ASCII transfer.

Thanks everyone
