A little contribution,

Before any questions, i want to express my admiration for the work = that i've=20 been done on

Gnu-win32.

I've two questions, one on the bash and &, the second, on the use = of pid,=20 gid etc.

bash and &

from the same bash,

launch of cygwish80 by :

-> cygwish80.exe &

-> ps -ef

TTY PID PPID PGID WIN32-PID UID STIME COMMAND

00 1000 1000 1000 146 1008 10:38:25=20 d:\Cygnus\B19\H-i386-cygwin32\bin\bash.exe

launch of cygwish80 by :

-> nohup cygwish80.exe &

-> ps -ef

TTY PID PPID PGID WIN32-PID UID STIME COMMAND

00 1000 1000 1000 146 1008 10:38:25=20 d:\Cygnus\B19\H-i386-cygwin32\bin\bash.exe

00 1003 1000 1003 80 1008 10:39:22=20 d:\Cygnus\B19\H-i386-cygwin32\bin\cygwish80.exe

00 1005 1000 1005 179 1008 10:39:55 d:\emacs-19.34\bin\emacs.exe

00 1007 1000 1007 92 1008 10:41:09=20 d:\Cygnus\B19\H-i386-cygwin32\bin\cygwish80.exe

In the two case, the only way to exit is to terminate the cygwish app = and=20 then to exit from the shell.

As we can see, the tty on wich the app runs is the bash tty, for the = two type=20 of launch. that's not what the nohup exec should do.

Pid, gid etc.

as described, i create the two system files on my /etc directory, = that is,=20 passwd and group.

Everyone::0:

it seems to me that, inspite of these description, there are = problems. For=20 example, if i lauch a bash,

and then create a file (for example toto) by :

-> echo toto > toto

a ls -l command gives :

-rw-rw-rw- 1 544 Utilisa. 6 Apr 4 10:59 toto

where does the 544 comes from and also is "Utilisat. du = domaine"=20 expression a valid one for gnu-win32.

also i remarked that even if i wasn't the owner of a file and it was = a=20 readonly one i was able to change its

rights an d then ownes it.

Is there a problem or am i doing wrong actions ?

Greetings.
