Unix, config files, and ^M

So, for those who have Unix and people hacking config files with DOS, how do you handle the ^M issue?

Normally it does not matter, though I have noticed some perl scripts will not run if there is a ^M on the #!bin/iwperl line.

However we just had an ugly one. someone changed iw.cfg and when there was an iwreset -ui TS would not come back up.

Goth this error in the iwserver.log:

Syntax error on line 425 of /u03/iw-home/iw-webd/conf/httpd.conf:
ProxyRemote takes two arguments, a scheme, partial URL or '*' and a proxy server
/u03/iw-home/iw-webd/bin/iw.webd start: iwwebd could not be started

Lead me to iw.cfg, ran dos2unix & everything was happy.

I could put dos2unix in my workflow as an external task, but I am curious if there are other options.

I am not certain what editoris putting the ^M in.

I have a dos2unix externaltask in one of my workflows. It's more of a "just in case" sort of thing, but it does the job and no one ever has to worry about it. When I have to look at a file that's got ^M all over it, I tend to just run dos2unix on it so I can read the text easier. I don't know of any other way to fix it. Getting rid of Windows would be a nice start Smiley Happy

how are you delimiting what files it shoudl run on ? I ran it on gnu grep to see what it would do to a binary. Toasted it pretty good.

run just a file type ?

I use a filter based on a regex that checks the file extensions and skips all the ones we expect would be binary.

It's the other way around...the filter uses a regex on file extensions to determine which files should go through dos2unix. It skips those not listed in the filter.

How about not using ms branded editors...

There are a million other editors out there that are great, and they preserve unix/dos formats....

Cant be that hard to keep yourself organised... can it?? Smiley Happy

So you're saying that the pain of convincing people to use the TeamSite GUI wasn't quite bad enough so we should also tell people to change their editor now, too? Piece of cake.. Smiley Happy

Alright Alright.....

I guess its never been an issue at the places Ive worked.
Pretty much all of the admin stuff has been centralised.

This little ditty will work on Unix (though it doesn't seem to work on W2K):

my $fname = shift;
if (-B $fname){
    print "$fname is binary - not changing\n";
    exit(0);
}
open(IN, "<$fname") || die " '$fname' ($!)";
my @text = map {s/\r\n/\n/; $_;} <IN>;
close(IN);

open(OUT, ">$fname") || die " '$fname' ($!)";
print OUT @text;
close(OUT);

I do like this fish, it allows you to feed it with xargs:
find . -type f -print | xargs -n1 dosmod.ipl

Of course it will likely be much faster if I write the logic within the script to traverse directories and take multiple files at once.
