Invoking ash for rebaseall

Invoking ash for rebaseall

[Ross Boulet]

My apologies if this is covered somewhere (FAQ, user guide,
etc.)  Rebaseall now requires being run under ash, but when
I run ash from "Start/Run" or from a cmd.exe prompt, it does
not execute /etc/profile and therefore does not have a path
to rebaseall (or any other cygwin directory for that
matter).

Granted, I could go in to windoze and add the cygwin
directories to my system path, or manually source
/etc/profile at the ash prompt.  But is there a flag to tell
ash to act as a login shell and execute /etc/profile?

Thanks,
Ross

Just use the following (from ash):

    $ PATH=/bin rebaseall

Umm, why should rebaseall require a PATH setting at all?  Wouldn't it be
easier to specify full paths for every command instead of telling users to
set their PATH?

Well, if the user does not have /usr/bin in their Windows path (instead
relying on /etc/profile to add it) and they try to run "ash rebaseall"
from a command prompt, they will get an error about not finding
cygwin1.dll unless /usr/bin is the CWD.

It would be nice if ash had a "-l" option as bash does to tell it to be
a login shell and read the profile/rc files.  But it doesn't, AFAICT. 
It seems to want to sense this by checking if argv[0][0] == '-'.  *sigh*

It would be easier to just add "PATH=/bin" near the beginning of the
rebaseall script than to use full paths for every command invocation.
Unfortunately, this would not solve the problem of finding rebaseall
itself.

Anyway, maybe the best approach is to add the aforementioned PATH
setting to rebaseall and instruct the user to execute rebaseall as
follows:

    $ /bin/rebaseall

Any other suggestions?

Actually, "ash rebaseall" will not work even if the user's PATH is set
correctly.  Unlike bash, ash does not seem to search the PATH to find a
script to execute:

    $ ash foo.sh
    foo.sh: Can't open foo.sh: No such file or directory

But, the following work:
    
    $ ash /home/jt/bin/foo.sh
    foo
    $ ash -c foo.sh
    foo
