However prepending '-' is (currently) the only method of invoking a login shell which works across all the packaged shells. So I went ahead and installed 3.1-1 to try it out. Here's what I found: chere did indeed stop working as advertised. Further experiments from a command prompt: --- start c:\cygwin\bin>bash bash-3.1$ exec -l bash [EMAIL PROTECTED] ~ $ --- end login shell executed (PS1 evaluated). Attempting the verbatim line from chere: --- start c:\cygwin\bin>bash bash-3.1$ exec -l /bin/bash bash-3.1$ --- end I haven't checked $0, but I'm guessing it's something like -/bin/bash, and this isn't triggering a login shell. chere passes the full path to the executable in case the shell isn't in the path. I can't remember if this was absolutely necessary, but it certainly works with the other shells. e.g --start c:\cygwin\bin>bash bash-3.1$ exec -l /bin/zsh ([EMAIL PROTECTED])[1] ~ $ ---end Regards, Dave chere maintainer __ Do You Yahoo!?

"bash --login" works fine, but the problem with "-bash" prevents chere from starting login shells. It may be possible to modify chere to use "bash --login", but this is still a bash bug, right? As I said, I noticed the problem first with chere. I confirmed the problem by adding echo "`date` ~/.profile" >> /tmp/dotfile at the top of ~/.profile. When I start a shell with "bash --login", I see the current date/time added to /tmp/dotfile. If I execute "exec -l /bin/bash", no entry is added to /tmp/dotfile with 3.1-1. An entry is added with 3.0-14. -- David Rothenbergerspammer? -> [EMAIL PROTECTED] GPG/PGP: 0x92D68FD8, DB7C 5146 1AB0 483A 9D27 DFBA FBB9 E328 92D6 8FD8 Your program is sick!

I couldn't reproduce the failure; can you provide more details?
Here's what I tried:
$ cat foo.c
#include
int main(int argc, char**argv) {
return puts(argv[0]);
}
$ (exec foo)
foo
$ (exec -l foo)
-foo
$ echo $BASH_VERSION
3.1.1(1)-release
So exec -l is correctly prepending the '-' to argv[0]. Is you
question about bash not behaving as a login shell when
invoked with argv[0] set to "-bash"? Have you tried
"bash --login" instead?

bash 3.1-1 "exec -l" doesn't start login shell
"exec -l" in bash 3.1-1 doesn't seem to start a login shell. This
prevents my chere commands from starting a login shell, too.
It works in 3.0-14.
I'm using a self-built DLL from 20060109 16:00:41.
