This may be a silly question, but is there a program out there that will handle a shar file under MS-DOS? thanks -- Brett G. Person North Dakota State University uunet!ndsuvax!ncperson | ncperson@ndsuvax.bitnet | ncperson@plains.nodak.edu

> This may be a silly question, but is there a program out there that will > handle a shar file under MS-DOS? No silly questions, only silly answers. Here comes one :-) : The MKS toolkit from Mortice Kern Systems (sp?) gives you a Korn shell "vi" and many other UNIX commands. With them you can process shar's (with some difficulty because of minor differences in "wc", "touch", "chmod" between the MKS toolkit and "real" UNIX). Since the MKS toolkit also contains a fine "cpio" you probably will want to use "cpio" archives instead of shar's. Frank "Happy MKS user" Slootweg, Hewlett-Packard, The Netherlands.

David, I do not have real fixes. I have however found my original notes. My original posting was not completely correct. There is no problem with "wc" but with "sum -r". Note: My experience is based on transporting shars made by *our* (Hewlett-Packard HP-UX) version of "shar(1)" to the MKS Toolkit environment on a PC. Sadly enough there is no such thing as *the* "shar(1)" :-) Details : ========= - ".ksh" extension : If you want to execute the shar directly its extension should be ".ksh". - "/dev/null" versus "/dev/null" : Our shars optionally contain a "sum -r" check per file. If they do then there is a construct like : if sum -r </dev/null >/dev/null 2>&1 then sumopt='-r' else sumopt='' fi to determine whether BSD or SYSV "sum" is available on the target system. MKS knows only about "/dev/nul" (one "l"). - "chmod" differences : Our shars optionally preserve the user and group ownership of the archived files and directories. If they do then there is a construct like : chmod 644 /etc/motd The MKS "chmod" only understands "+w" etc (i.e. no octal mode). - "sum -r": Difference in counting characters : Our shars optionally contain a "sum -r" check per file. When a UNIX "shar" is uploaded to a PC most upload programs will insert a CR before the LF at the end of each line. They need to do this otherwise the resulting file is not a valid MS-DOS text file and hence not a valid script for the MKS Korn Shell. However the character count *in* the archive is not adjusted accordingly so the unshar will "fail" on a "sum -r" check. Workarounds : - Remove the "sum -r" check from the shar. - Change the way "sum -r" reads the file : Our shars have constructs like : set `sum $sumopt </etc/motd`; if test $1 -ne 47574 then echo ERROR: /etc/motd checksum is $1 should be 47574 fi Change this to : set `tr -d "\015" </etc/motd | sum $sumopt`; if test $1 -ne 47574 Obviously this is only valid for text files (i.e. not binaries), but this is the most common case going from UNIX to PC. (UU)encoded binaries are fine because they are text files for both UNIX and PC. - "touch(1)" differences : Our shars optionally preserve the time stamps of the archived files. If they do then there is a construct like : touch -m 1023160389 /etc/motd touch -a 1219150089 /etc/motd "Real UNIX" (at least System V) has the following syntax for "touch(1)" : touch [-amc] [mmddhhmm[yy] files The MKS "touch" uses : touch .... [yymmddhhmm.ss] Summary: *I* prefer to use UNIX/MKS "cpio" and I *do* like the MKS Toolkit (even with the above mentioned differences).

Hi all you unsharers out there, Messy-Dos users should be aware of Rick Salz' cshar. As far back as version 1.0 of this program, Rick included sufficient code to produce an sh (called shell) capable to sharing and unsharing standard archives. I understand that there is a new version available with enhanced capabilities from archiving sites ( Rats! I missed the posting.). This fine program works well under UNIX and under MessyDos, when compiled for that environment. One caveat, I can't remember whether I had to come up with my own "wc"", "sum", or "chmod" clones but I think not. Do have a look, I've been using this package since April '87, hence the foggy recollections. Compilation was under MSC 4.0. I assume moving it to MSC 5.x and TurboC will be no big deal. You can usually find Rick's postings in comp.sources.unix so that's the place to search in the archives. Good Luck, ger -- G.
