Archive-name: ms_sh-1.6/patch02
This is patch 1.6.3 for the MS-DOS Shell. It fixes a number of minor
problems in the shell, addes a few new features and fixes on major problem
in the directory handling functions. The changes are detailed in the
Readme update and the change logs. Some of the files have changed because
I have moved to GNU RCS 4.2.
Most of the patches that Kai Uwe Rommel posted in comp.binaries.ibm.pc.d
have been implemented. The main one I left one was that which allowed
the user to execute COMMAND.COM internal commands by having COMMAND.COM
automatically invoked. There were three reasons for leaving it out 1) the
problem of wild card expansion - the shell does wildcard expansion before
invoking a program which is likely to cause command.com to reject the
command; 2) if the user really wants these commands, they can be generated
just as easily using functions:
dir () { command /c dir $1; }
and 3) some of the command.com internal commands have Unix equivalents and
the Unix equivalent tend to be more feature loaded. If you don't like it,
you can always install Kai's patches yourself. This is not to say don't
mail me changes. I just don't think this one is appropriate.
Other than that, here it is. The two shars generate Patch1.6.3 which
should be applied via patch -p <Patch1.6.3 from the shell source root
directory.
