You can permanently edit environment variables in Windows using
control panel, system, advanced, environment variables.  Or for
a single use, you should try 'set /?' in a cmd.com window, for ideas
on setting environment variables in batch files.

Alternatively, you could do:
rxvt -e /bin/bash --login --rcfile /cygdrive/h/.bashrc -i

Thus combining your current configuration with the way you want it to be...

Ahhh, most cool.  That command with switches works from 
the cygwin bash prompt, but not from the DOS prompt, 
which tells me it wouldn't work from a batch file.  The 
following does work from DOS:

h:\cygwin\bin\rxvt -e /bin/bash --
rcfile /cygdrive/h/.bashrc -i

But the following does not:

h:\cygwin\bin\rxvt -e /bin/csh --login --
rcfile /cygdrive/h/.bashrc -i

The difference being that "--login" breaks...  Any
idea why --login es no bueno?  Is --login really
needed?

Thanks!

There should be no space between "--" and "rcfile", but I guess you know
that (it's hard to tell whether that was your mailer's linewrapping).

Now, this is interesting...  Why would you expect bash options to work for
csh?

If this really is a typo and

h:\cygwin\bin\rxvt -e /bin/bash --login --rcfile /cygdrive/h/.bashrc -i

does break for you from a DOS prompt, please run

h:\cygwin\bin\bash --login --rcfile /cygdrive/h/.bashrc -i

from the same DOS prompt and tell us what output it produces.

Re your other message, it's Geordi ;-)

Anyway. Why csh? I can't tell you what the options would be for that.. 
You'd have to check the man page

As for the command I gave you not working from a command prompt - it 
does, as long as you are in your cygwin bin directory.. Otherwise, in a 
batch file, yes you will need to prepend rxvt with C:\cygwin\bin\ , or 
whatever the path to the executable is.
The same applies to if you just make a shortcut for it..
See the default cygwin.bat for reference.

Bash Window Geometry

[Bubba Jones]

Is it possible to tell the bash prompt where I want it positioned on my desktop?  Using X Windows I specify size and location with "--geometry".  Is there anything comparable under MS Windows?

First off, <http://cygwin.com/acronyms/#PCYMTWLL>.  Thanks.

Now, if you're starting bash from a shortcut (e.g., the one Cygwin
installation puts on your desktop), you can change shortcut parameters to
put the window anywhere you want (Properties->Layout->Window position).

I think my mailer might be goofed...  I don't see an option
for that.  I'll fix it the ole fashioned way though with a
manual CR/LF :) .

Thanks, but I'm looking for something like the "--geometry"
feature of X.  I want several bash windows on my desktop in
strategic locations when I double-click a .bat.  I'm guessing
that a .bat file can contain several calls to bash with the
geometry pre-defined.  Right now my cygwin.bat file contains:

@echo off
cd \
C:\Cygwin\bin\bash --rcfile /cygdrive/h/.bashrc -i

Is there any way to have the call to bash set geometry?

Good enough. :-)  You might want to complain to Anheuser-Busch about this
and the quoting, though...

Yeah, I thought of adding that bash itself has no control over its
geometry -- after all, it's just a shell.  The geometry is specified by
the window that contains the shell (be it a console window or an
application window).  There may be a launcher program that sets those
(after all, if a shortcut can do it, there must be a command-line way,
right?), but I don't know of any.

Heh.  Two problems: (a) you're not starting a login shell, and (b) why do
you have /cygdrive/h as your home?  Sounds like your $HOME setting is
inconsistent with your /etc/passwd...

> Is there any way to have the call to bash set geometry?

As I said above, not to bash itself, but there might be a way of
controlling the position of the console window using some Windows means
(maybe a program in the Windows Resource kit?).

Good eye.  I have my HOME set in my .bashrc.  I'm
using an "organizational" computer.  "They" "nazified"
the systems, so I stuck HOME on my network folder.
When I do an "ls -l /etc/passwd", I get,
"no such file...".  I'm not sure what "they" did, but
"they" don't seem to want to answer my questions about
"their" cygwin configuration.  I asked to have
vi included in the configuration, but no response...

I decided to take matters into my own hands.  I
installed cygwin on my network drive and specified
vi and some other stuff, then set my PATH to look at
my installation after "their" installation.  It seems
to work ok.  I had to delete/move my cygwin1.dll so the
system wouldn't freak out.  The system preferred the
cygwin1.dll that is part of the system config, not
my config (I hope that makes sense...).

Do you see any problem with the /etc/passwd
mismatch?

I installed rxvt.  That solves the problem with
the geometry thing.  I am in my happy place now :) .

My hope is that if enough people bug those online services, some of them

You do know that you can have your own mounts pointing to wherever *you*
want (in effect, having a separate Cygwin installation)?  If theirs is
missing /etc/passwd, it's seriously broken anyway.

I forget, did you ever attach the output of "cygcheck -svr" (as an
uncompressed text attachment) as requested in the Cygwin problem reporting
guidelines at <http://cygwin.com/problems.html>?  If not, you should do it
so that we have enough details about your installation(s) to try
diagnosing the problems.

Why not do the other way around?  Remove their installation from the PATH,
add yours, issue the following commands (assuming your Cygwin is installed
in H:\cygwin):

mount -ufb 'h:\cygwin' /
mount -ufb 'h:\cygwin\bin' /usr/bin
mount -ufb 'h:\cygwin\lib' /usr/lib

That way your install would be completely independent from theirs.

I'm assuming you installed Cygwin from one machine and use it from
another, otherwise installing for "just me" would have set up the proper
mount entries already.  Again, the output of "cygcheck -svr" would have
told us whether this is the case.

> Do you see any problem with the /etc/passwd mismatch?

Yes.  Many things that rely on authentication and permissions will not
work properly if certain usernames (including yours) are missing from
/etc/passwd.  Your /etc/group will also need to be up-to-date.

Until the problems start.  Let's try preventing them.  The first step
would be to see what your and their installations look like (via the
output of "cygcheck -svr").

...or using a terminal that lets you control the geometry (e.g., rxvt) as
others mentioned.

Thanks for the tip.  I'll do that.

You're smart (recall Star Trek TNG episode when
Jordi <sp> was kidnapped because "he was smart"...).

My network quota is 200 MB, so, my plan was to install
the cygwin binaries that I needed and were missing
from the "organizational installation" so I could
have a "mean and lean" use of drive space.  Now that
you mention the separate installation thing, I
believe I can attach a USB drive to this machine.  If
I can do that, I will do a real cygwin install and
say phooey on them :) .  That will keep "them" happy
and make me very happy.

I just wanted a few cygwin binaries...

But of course...  I think the USB drive install will
save the day...

If you use rxvt instead of the standard console window, then just try
the -geometry option...

 Note that if you have a correctly defined $HOME at the time when you start
rxvt, then you can use the $HOME/.Xdefaults file to define the geometry and
more
(see man rxvt)

e.g. running something that mimics this; (UNTESTED!)

	bash <<EOF
	HOME="/home/$(id -un)"
	export HOME
	. /etc/profile  # necessary?
	rxvt -ls /bin/bash -li &
	EOF

from cygwin.bat will have you up and running, with settings from .Xdefaults
in your (default) home dir (as setup by /etc/profile).

NOTE: it is necessary to do tricks to accomplish the above,
       as .bat/cmd.exe doesn't allow "here docs".

I have something similar setup on my work machine, but I don't remember how
it is exactly - @home now.
 Another optional "path" is to have $HOME be the null string (from
Windows/cygwin.bat) and have /etc/profile pathed as indicated below.
