Hi,

I guess you'll hate me for mentioning this, but if
it's going into cygutils, please implement the
options --help and --version to do the obvious things.

Unless you're going to do a couple of pages of text for
info/man etc. :-))

util-linux's rev doesn't support any options.  However, the man page is 
copied below:

      rev - reverse lines of a file

SYNOPSIS
      rev [file]

DESCRIPTION
      The rev utility copies the specified files to the standard output,

Re: running mks toolkit and cygwin on same machine

Why not just roll-your own 'rev'?

Included is a trivial 'rev.cc' that will handle any size argument list that
cygwin is able to pass it. It should include <algorithm> to support gcc 3.1,
but for some reason it couldn't process templates when I included that.
Sigh.

Compile with
g++ -o rev.exe rev.cc

Fine by me. It's probably even codeable in bash/ash scripting, but I'm not a
shell guru.
And, it's hardly likely to require maintenance :}.

Yes, it's been on my todo list for some time.  Here are the util-linux 
progs that I believe still need to be added to cygutils:

colcrt  - filter nroff output for CRT previewing
colrm   - remove columns from a file
column  - columnate lists
rev     - reverses the characters on each line of each file
mcookie - generates magic cookies for Xauth

I have the util-linux code for each of this, plus man pages.  I just 
need to munge them up so they build within cygutils...time, time, time...

Would the cygutils package be a suitable home for two other
util-linux programs: ipcs and ipcrm?

I have these now compiled and working against the cygwin_daemon
branch.  Since these presumably aren't going to be part of the
cygwin package and I'm loath to create a package just for these
two utilities, I'm keen to find some other existing package in
which to lose them.  They're unlikely to need much support (once
I've hacked them up properly).

Yes, Robert and I have talked about that in the past.  cygipc includes 
them, but once cygdaemon is official I'll add them to cygutils.

Currently, cygutils includes a few IPC test programs (but not ipcrm or 
ipcs) -- but those are only built if cygipc is installed, are are not 
included in "official" cygutils package since cygipc isn't official.

If you can
   1) give me the code -- see cygutils' HOW-TO-CONTRIBUTE document
   2) also come up with an m4 macro for configure.in that I can use to 
detect the presence of a cygserver-capable cygwin1.dll

Then I have no problems adding ipcs and ipcrm to cygutils BEFORE 
cygserver goes gold.

Thanks, that's good.  I'll put that together once I've fixed up
ipcs and ipcrm right and proper.

Robert,

Perhaps this is another miscellaneous utility best suited for inclusion in
cygutils?

Cheers,

running mks toolkit and cygwin on same machine

[Scott Dudley]

does anyone have experiences with running mks toolkit and cygwin on the 
same machine?  my company's customers run mks but i'd very much like to 
attempt a cygwin test on one of these systems.

many thanks.

[Paul Coltrin]

Scott,

From my limited experience, they seem to co-exist reasonably well.
But it depends on what you need to do.  Unless it has changed very
recently, the Cygwin installer does not contain a ksh.  I have
downloaded and installed the ATT ksh into my Cygwin installation but
I am finding that converting scripts from MKS ksh to Cygwin/ATT ksh
is not trivial.

After installing Cygwin on a WIN2000 system with an existing
MKS installation, the two installations seemed to "lock horns".

I was able to establish peace by removing the MKS-related
environment variables from the system configuration (Start ->
Settings -> Control Panel -> System -> Advanced -> Environment
Variables) and moving them into profile.ksh.  Specifically:

	MKS_TK_PATH_BACK
	NUTCROOT
	ROOTDIR
	SHELL
	TERM (value had been "nutc")
	TERMCAP (value had been "E:\MKS\etc\termcap")
	TERMINFO (value had been "E:\MKS\usr\lib\terminfo")

In particular, the TERM* values seemed to be causing of alot
of the problems; Cygwin likes TERM=cygwin.

I also installed the ATT ksh -- there was a thread about this
two or three weeks ago -- but understand that a KSH package
for the standard Cygwin setup is on the way.  Have also had
some small problems porting scripts, one of which being that
"egrep" must always be changed to "grep -E".

Though Cygwin seems to have left MKS in the dust for most
of the functions I am interested in -- vim vs. vi, mutt
vs. mailx, fetchmail vs. something-that-didn't-work-for-me,
procmail vs. nothing -- there are a few commands that I still
use in their MKS versions:

    cpio      - is this out of fashion now, or what?
    flip      - changes CRLF endings; no equivalent in Cygwin?
    more      - sometimes I do not want the text to disappear from
                the screen on exit
    find/grep - the MKS versions can handle larger numbers of 
                arguments, though xargs solves the problem in Cygwin
    rev       - reverse order of characters in a line

Thomas,

- cpio
   Available, though little used, to my knowledge
- flip
   Use dos2unix and unix2dos
- more
   Available, as is "less" a superior alternative
- find / grep (arg list limits)
   All Unix / POSIX systems have argument list length limits,
   which is at least one reason why "xargs" exists.
- rev
   Unavailable, as far as I know

I know "less" is better, but sometimes I don't want the output
to disappear when I exit the pager back to the prompt -- as
when I have just successfully grepped for an email address.
Didn't see any flags for that in less (or vim, for that
matter).  Not a big deal, can always "| cat"...

From less(1) man page:

       -X or --no-init
              Disables sending  the  termcap  initialization  and
              deinitialization  strings to the terminal.  This is
              sometimes desirable if the deinitialization  string
              does   something  unnecessary,  like  clearing  the
              screen.

I have:

	export LESS=-X

in my .bashrc.

Hopefully you now have no reason to use "more" instead of "less"!

Regards,
David

yes, it is.  the big difference between cpio and tar in ages past was
that cpio could handle devices.  (arguably, complete lists in
configuration management are handled much easier by cpio's stdin
filename input method).  however, gnutar now handles devices just as well.
in addition, gnutar handles major compression techniques internally.
source for gnu cpio (i have used ver. 2.4.2 for years) is readily

easy to do in any shell:  invoke /bin/tr to do the translation
you need.  e.g.  for cr to lf:  cat $file | /bin/tr '\015' '\012'

[for those of you familiar with it, this invocation qualifies for
a Useless Use of cat award.
(http://www.ling.helsinki.fi/~reriksso/unix/award.html).  however,
it generalizes the technique for this example and easily allows for
rapid substitution of other i/o methods.]

I do not see it in the Cygwin Setup Select Packages list.  Is it an
alias of less?

No, it's a actual, standalone package.  You probably need to click on

Yeah, but cpio is still valuable for mucking with rpm's.  I often do 
this, when I want to extract code without installing the rpm...

rpm2cpio foo.rpm | cpio -i --make-directories

Granted, we don't have rpm yet, so...

d2u and u2d are already in the cygutils package.

Yep.  But don't use it -- less is much better.

This is on my TODO list for cygutils.  On linux, it is part of the 
util-linux package, a grab bag of random small utilities.  On cygwin, 
cygutils is the grab bag of random small utilities: hence...

I've attached the util-linux source for rev.c -- it's a bit more complex 
(complete?) than some of the other implementations...I'll probably use 
it as the basis for cygutils' version.

as of right now, the AT&T "ast" package isn't an official cygwin package 
(e.g. installable by setup).  That may change, eventually.

Why?  Works fine for me.  But a hard link of egrep.exe
and grep.exe (and fgrep.exe) rather than symlink of
egrep -> grep.exe (no .exe) might help.

Hmm, I did not make any links, so assume that setup.exe
did this:

lrwxrwxrwx    1 Administ       15 May 22 17:53 /usr/bin/egrep -> grep

..and that there must be a good reason why hard links are
not the default for such things.  Will give this a try when I
get a chance to read up on what "links" mean under WIN2000...

Re: running mks toolkit and cygwin on same machine

[Randall R Schulz]

Tom,

Only NTFS file systems support hard links. Symlinks work on all file systems.

I presume that the symlinks used for command aliases in Setup.exe's 
packages are present in the tarballs themselves, with no extra work (beyond 
embodying the Cygwin tar code or an equivalent) required by Setup.exe. 
That's one of the things about Cygwin TAR that makes it a requirement when 
dealing with TAR archives bearing such Unix TAR features and why other 
"compatible" TAR processors aren't suitable.

Randall
