bash -s from .bat file

bash -s from .bat file

[earl.chew]

I have a batch file which I wrote for b18. It basically
reads:

sh -s %1 < \a\b\c\foo.sh

This worked as expected, but fails under b19.1. I notice

a. I must use bash instead of sh.
b. Even after using bash, the contents of the script
   are not read and executed correctly. Weird things
   happen (eg : causes much confusion).

Using:

sh //e/a/b/c/foo.sh %1

appears to work... but unfortunately is not drive
independent :-(

Can anyone explain what's going on?

Earl

Get the latest coolview dll from Sergey:
   http://miracle.geol.msu.ru/sos/ !

With this beast you can avoid the crashes and set CYGWIN32 env var.

I see. I can't set CYGWIN32 in 19.1 -- it causes cygwin32 to crash --
this is mentioned in the faq :-(

I'll try fiddling the file to make it binary (no \r).

You have something set improperly because all this works for me fine:

E:\>cat foo.sh

: bar=1
echo Hello


E:\>bash -s <\foo.sh
Hello

E:\>bash \foo.sh
Hello

What versions are you running for Cygwin and bash?  I'm running Cygwin b19.1
with something close to Sergey's version.  bash is 2.01.1.  I'm also using
binary mounts on NT (4.0 + sp3).

Re: bash -s from .bat file

[Mikey]

your CYGWIN32 env var
needs to be set to binmode
and you need to get rid of \r
from foo.sh.

or you need to set nobinmode
and make sure foo.sh has \r\n

if \a\b\c\ is ANYWHERE in your mount table,
you need to make sure the mount entry matches the mode of
foo.sh, either \n or \r\n

mixing them won't work.

Sorry, I meant to write:

bash -s %1 < \a\b\c\foo.sh

I can understand reasons why ash doesn't work --- but I would
have thought that bash would be ok.

I've done some more experimenting. Here is a small shell script,
c:\foo.sh:

: bar=1
echo Hello

I type:

C:\>bash -s < \foo.sh
Hello
: command not found

C:\>C:\tmp>bash \foo.sh
Hello

It turns out that I get the same behaviour if I move this to e:\foo.sh
and on e: drive type:

E:\vob>bash -s < \foo.sh
Hello
: command not found

E:\vob>bash \foo.sh
\foo.sh: \foo.sh: No such file or directory

Note that bash is unable to find foo.sh using the drive relative Win32
path name.

It is most likely because sh which is a port of linuxes ash ends up
trying to open abcfoo.sh instead of \\a\\b\\c\\foo.sh.

This is probably true (I haven't tried it yet), but doesn't really
answer the question why foo.bat containing

sh -s %1 < \a\b\c\foo.sh

run from a Win32 command shell doesn't work on b19.

Your stated problem on the directories can be solved like this:

  bash#> cd /
  bash#> ln -s //x/a a

now when you do `sh -s /a/b/c/foo.sh %1' it should be able to find it
because //x/a is symbolicly linked to a.

I should have emphasised that this is a batch file that runs from cmd.exe.
So foo.bat contains:

sh -s %1 < \a\b\c\foo.sh

: > a. I must use bash instead of sh.

Ok. I'll try to put together a small sample tomorrow.

: > Using:

: 
: Have you tried `sh /a/b/c/foo.sh %1'?

Yes. That works (as expected) --- but the semantics are subtley different.

I've got a script that I want to have execute irrespective of the drive
it happens to installed on. In this instance, I have a bunch of files that are
installed in directory x:\a\b\c. The drive relative path (in Win32 terms)
is \a\b\c.

I can get to the file in Cygwin only by giving an absolute path //x/a/b/c.
Thus although sh /a/b/c/foo.sh "works" from a cmd.exe batch file --- it
cannot find the file in a drive relative way --- only \a\b\c\foo.sh can
do that.

Let me know if there's any confusion here.

So, the only way that I could think of to get hold of the shell script in
a drive relative way was to get a Win32 batch file to locate the script:

foo.bat:
	sh -s %1 < \a\b\c\foo.sh

foo.sh:
	# Rest of script

This way, I can "execute" the shell script from a Win32 command shell. Or
I could until I tried b19 :-(

Have you tried `sh /a/b/c/foo.sh %1'?

A confusion between the UNIX filesystem and the WIN32 filesystem and
the emulation of the UNIX filesystem on the WIN32 filesystem.  

With UNIX the user sees one big continuous filesystem and they aren't
concerned with devices/drives.  The UNIX administrator has to be
concerned only with what directories are to be mounted on what
devices/drives.

With WIN32 the user has to be concerned with a filesystem that has
many devices/drives and the user has to determine what directories are
loaded on what devices/drives.  The WIN32 administrator only has to be
concerned that there are devices/drives, he isn't concerned with what
is on the device.  So much for a _USER_FRIENDLY_ system.

With CYGWIN32, the project has tried the best it could to
emulate/merge the UNIX filesystem on/with the WIN32 filesystem. 
Unless you have a clear understanding of both filesystems and their
differences then this can lead to confusion.

-------------------- IMPORTANT UPGRADE NOTICE ------------------------
You should get the following to update your cygwinb19 package:

Sergey Okhapkin's coolview package which contains an updated 
cygwinb19.dll.  (Yes, even if you've already downloaded the b19.1 
update from the Cygnus Site).

Mumit Khan's compilation of EGCS for the cygwinb19.dll; especially if 
you're using the C++ compiler.  The current version of the compiler
that 
comes with the tools has lots of problems that have been fixed with 
the EGCS version.  This is a drop-in replacement for the GCC toolset.

URL's are listed above.
