I've downloaded some text files from a UN*X machine via arc and xmodem. I've
got a pseudo-sed script for edlin I want to run on them (thanks Clayton,
thats a real useful tip you posted a few months back) but it turns out that
the lines end in line feed. Edlin rides the porcelan bus unless it
sees a CR LF combination. So, is there an easy way in DOS or MKS vi
to automatically do this conversion?
I see a few solutions, all of which stink up the place.
1) In UN*X run the files through sed before archiving.
2) In UN*X modify the source to my archiver.
3) Write a C program on the pc. (this is my favorite unless it's already
been done).
4) Give up on automation and make the changes by hand. This would take hours.
5) Make the changes on UNIX with sed, archive, and download.
Thanks
Jim

MKS vi automatically converts LF characters to CR/LF pairs when it writes the file to disk. The trick is that you have to force it to write the file (if you don't edit the file somehow, then the copy on disk will not be updated if you do a ":wq", hence the "!"). Disclaimer: this works with the 2.2b version of vi.

The trick is that you have to force You can also get this behavior with microemacs, cse (posted by, um, whatzisname from Colorado School of Mines), a recent posting of 'ed'... If you want to write a filter, it's remarkably easy in something like TurboC -- open the file in binary mode so that LF is sufficient to mark a line. Read in convienient-size chunks, write to a file that's been opened in text mode, and the newlines will "automagically" be sent out as CR/LFs. I expect MSC and other languages will offer the same binary/text behavior. -bob,mon "In this position, the skier is flying in a complete stall..." -- -bob,mon "In this position, the skier is flying in a complete stall..."

If you have access to a copy of PC-NFS, it includes the programs DOS2UNIX and UNIX2DOS that will do the conversion for you. The following programs are filters that will work on a Unix system.

I prefer this method, what I want from an editor is for it to write my file AS IS to the disk unless I explicitly tell it the changes to make. Of course, it would be nice if I could tell it to make this conversion..... I found another oddity with this editor. There is a :source command that allows you to read commands from a file. So I made up a file with 8 search and replace commands in it, figuring that vi'ing and :source'ing 5 files beats doing things manually. Hey, guess what? As soon as a search string is not found it aborts execution of the source'd file! Unfortunatly, not all conversions need be done to all files. At this point I uploaded things back to the vax, made my changes with sed, stuck a bloody CR at the end of each line, and re-downloaded the mess. God I love DOS. Jim "I'll never quit drinking.

In fact, most of the MKS tools will read the files which have only linefeeds at the line ends, and will rewrite the file with cr-lf. For example, you can run sed with just the p command. The exceptions are cat and tr, which read and write the file in binary mode. -- Gerry Wheeler Phone: (519)884-2251 Mortice Kern Systems Inc.

I imagine the 'source' command's behavior is simply based upon unix's vi :source behavior. MKS vi behaves exactly as unix vi in all aspects (I can't find one discrepancy). Why upload to the vax to used SED? You should get SED for the PC. GNU's version of SED is public domain, sources are available, and it seems quite complete... As far as a simple way of adding CR's to a LF delimited file, most C compilers stdio library will read LF delimited files properly, and write them out CRLF delimited (as long as you don't select file type of binary)... So all you need to build a pipe command to add cr's is a program such as the following: #include <stdio.h> main() { char line[255]; while (NULL != gets(line)) puts(line); } Just compile this to ADDCR.EXE or ADDCR.COM, and then: C:\> addcr <infile >outfile or C:\> type infile | addcr Will nicely add CR's to the file... -uunet!watmath!dalcs!dalegass@dalcsug.uucp

The best methhod I know is to use Zmodem, not Xmodem. Omen Technologies'
`dsz' program, available on many BBSes and on comp.binaries.ibm.pc, etc.
comes with the Xmodem, Ymodem, and Zmodem for both MS-DOS and UNIX.
Then, to download a text file from UNIX to MS-DOS, just use the command:
sz -a file1 file2 file3 ...
and to upload from DOS to UNIX, just use the command:
dsz sz -a file1.txt file2.txt file3.txt ...
Dsz has many other abilities too, especially if you register it. I love it.
(I have no commercial connjection with Omen--I'm just a satisfied customer.)
