default shell

default shell

[Dawid Ferenczy]

Hi,

   it's not a big deal, I just wonder what to execute, if I would like to 
execute user's default shell (defined in /etc/passwd). For example in cmd.exe, 
ConEmu or Console2. I don't want to hardcode a shell anywhere (in console 
emulator configuration, some batch file etc.), I just want to auto detect 
user's default shell and execute it. If it's possible :) Exactly the same what 
does mintty.

Thank you and have a nice day!

The answer depends on what you actually trying to do.
Else, there's no simple answer. Default "default" shell is bash, but user can
pick any other, and mintty does some trickery to find it out.
You can try something like

USERSHELL=$( XXX=$( getent passwd $USER ) echo ${XXX##*:} )

but there's no easy equivalent for *NIX scripting in CMD, that does this.
Soo.... back to the original question. What you are trying to do, for what
mintty isn't sufficient?

At the time I was asking, I was asking for advise to do it or not, and possible
how.

But now, several hours later and after changing the comspec from the
controlpanel;
I don't think the change had any effects.

The reason I asked was because I was messing around with the at-command and
thought it might could make some difference to have bash as default-shell.

For the time being I'm running at-commands like "c:\cygwin\bin\bash --login -i 
script_to_run_including_path.sh"

Is this the preferred way of running at-commands with bash?

Stein

Are you asking if it is ok or are you saying that you've tried it and it
works for you.

Default shell

[Stein M. Eliassen]

Hi again,

Is it wise to replace the default cmd.exe with bash in NT?

"Old" bat-files will work okay regardless, don't they?

And is the correct registry-setting for this:
\localmachine\system\currencontrolset\control\session
manager\environment\comspec?

Maybe this subject could make it into the FAQ sometimes...

Stein
