Preserve Unix Line Endings with Windows Intellij

Just a quick note: If you're editing shell scripts and the like on a Windows platform with Intellij (my version is 9.0), here's how I succeeded preserving Unix-style line endings. First, to more accurately describe the problem, a given file has been saved in the Windows IDE, then checked in to a Perforce repository, and then sync'd onto a Unix server. When editing that file with vi, the settings [dos] [noeol] appear - and I'd like to get rid of these. I do not want a DOS format, and I do want an end-of-line. Here are the steps I took:

1. First, set the Intellij "Line separator" property to Unix - enter "Line separator" in the Settings search box, then choose the Code Style - General result. The Line separator property is towards the bottom of that panel. Yes, it does state "for new files", and not surprisingly I did not succeed simply editing an existing file - the DOS-style format remained after I saved and checked it in (Perforce). But, this does cover things going forward - at least this gets rid of the [dos] problem on new files - however, on the subsequent edit of the new file on Unix, the [noeol] is still there.
   
2. To get rid of the [noeol] problem, I set one more thing in Intellij: in IDE Settings - search for "Ensure blank", which will bring up the optional checkbox for "Ensure blank line before end of file on Save". Check that option, and from here it appears that newly created files in the IDE will no longer have the [noeol] affliction. To address this problem on existing files, simply edit/save/check-in the file with the IDE. Probably, you could also just add a blank line at the end with vi on Unix - I didn't try this, but it sounds reasonable.
   
3. To fix the [dos] problem on existing files, open the file in vi and type ":set ff=unix". Save, check in, and this problem should not reappear even after subsequent edits in the Windows IDE.

Don't forget, depending on what steps you take from above, that if you have set your CVS system to "revert unchanged" files (as I do with Perforce), that you may need to actually change something that the CVS will notice before it will check it in. Huh, maybe adding some comments...

Hope that helps. I'm sure I'll bump into this headache again, so I can also hope this helps me when that happens.
