Ok, I can't give this script thing up. I'm working on it while on
vacation.

a) Why do I want script to work? Many folks have given alternatives, but
I have a pretty hard req for a "Script" like utility:

1) I'm using some NT code that that allows me to launch a bash script,
but I can't feed any stream processing steps, such as:
bash --login scripttorun.bsh parm1 parm2 | tee IwishIcouldDothis.log

2) Also, some folks (at least 3 so far) have reviewed the expect book
and posted a snippet of using expect. While interesting, the major
reason I'm not using that is because it only tracks commands as issued,
not the output each command throws.

b) Where I'm at in the compile of script.c located in util-linux-2.11d:

Corinna's reply stated I could use : Open with O_NOCTTY.

I did this code, attached below, but get the following error.

perry@PERRYT20
/cygdrive/c/dykes/data/wrk/mkwf/activity-work/typescript/util-linux-2.11d/misc-utils

$ gcc -I../lib script.c -o script.exe
script.c: In function `main':
script.c:125: warning: assignment makes pointer from integer without a
cast
/cygdrive/c/DOCUME~1/perry/LOCALS~1/Temp/ccIAem9J.o(.text+0x71c):script.c:
undefined reference to `cfmakeraw'
collect2: ld returned 1 exit status

Assuming I can figure out warning or ignore, the ld error has me
stumped. Is there a cygwin programmer who knows what this means. I'm not
sure how to debug it. I looked through ld man page and other content for
references to cfmakeraw, and so far not sure what this is or how to get
rid of error.

As always your helps is appreciated well in advance.

Regards,
Perry

Here's a link to info about cfmakeraw:
http://www.linuxbase.org/spec/gLSB/gLSB/baselib-cfmakeraw-3.html

I gather it's supposed to be defined in termios.h

I no longer have your original email so I need you to refersh my memory. 
What is your goal in wanting to capture all of the output of the script?
Does it *have* to be in Script format? Is it just for logging of debugging?
Does the following help you?

You can put the following in your script:

#---------- Start of script -------------------
	#!/bin/sh -x
	(
#----------------------------------------------

# Example body of script 

	grep term /this_file_does_not_exist     # will cause output to
stderr
	grep term /usr/include/sys/termios.h    # will cause output to
stdout

#---------- End of script ---------------------
	) > myoutput.lst 2>&1
#----------------------------------------------

All output including the commands issued will end up in 'myoutput.lst'.
This will work for Bourne derivatives (bash, ksh, etc.) also.

Whoops, here is the source.

And here is how I'm compiling:

gcc -I../lib script.c -o script.exe

Hoping maybe a better command line parm list to avoid problem in
previous post.

Open with O_NOCTTY.

Cygwin supports streams ptys:

    master = open ("/dev/ptmx", O_RDWR);
    grantpt(master);
    unlockpt(master);
    slave = open (ptsname(master), O_RDWR | O_NOCTTY);

Unix "script" utility continued... cygwin newbie need a porting expert's help..

[Perry Dykes]

Still working on making a cygwin "script" utility. First, the source,
found the "script.c" utility in the util-linux rpm. Now attempting to
port. Got the compilation down to 2 problems, the warning, I can
address, but the error gcc spits out at line 387 has me stumped. Does
anyone know if the the following TIOCSCTTY attribute is supported or has
an alternative value:

       (void) ioctl(slave, TIOCSCTTY, 0);

Here is the compilation output:

$ gcc -I../lib script.c -o script.exe
script.c: In function `main':
script.c:125: warning: assignment makes pointer from integer without a
cast
script.c: In function `getslave':
script.c:387: `TIOCSCTTY' undeclared (first use in this function)
script.c:387: (Each undeclared identifier is reported only once
script.c:387: for each function it appears in.)

The modified source is attached. In the source file, I have been
avoiding the PTY support, not sure cygwin has that. Advise or where to
look for info on this would be great.

Thanks for any help you can offer.

Perry
