:DESCRIPTION:
|
|
The AT&T Software Technology ast-ksh package from AT&T Research
|
|
contains ksh and support libraries. This is the minimal set of
|
|
components needed to build ksh.
|
|
|
|
:DETAILS: cyg
|
|
:README:
|
|
This package installs a standalone ksh93 executable ksh93.exe
|
|
and its man page ksh93.1. If /bin/ksh.exe does not exist then
|
|
these symlinks
|
|
/bin/ksh.exe => ksh93.exe
|
|
/usr/share/man/man1/ksh93.1 => ksh.1
|
|
are created. This allows alternative ksh implementations,
|
|
e.g., /bin/pdksh.exe, to be selected by changing the ksh.exe
|
|
and ksh.1 symbolic links. In addition, ksh and ksh93 paths are
|
|
added to /etc/shells if not already present.
|
|
$()
|
|
Each builtin or special command accepts the --man and --html
|
|
options to show the man page on the standard error. The --???
|
|
option describes the self documenting options available to all
|
|
builtin and special commands.
|
|
$()
|
|
The standlone ksh is statically linked with the AST libcmd
|
|
library which provides several builtin versions of /bin
|
|
commands. "builtin | grep /opt/ast/bin" lists the libcmd
|
|
builtins on the standard output. /opt/ast/bin/FOO accesses
|
|
the FOO builtin, whether the /opt/ast/bin directory exists
|
|
or not. "builtin FOO" allows /opt/ast/bin/FOO to be accessed
|
|
as FOO, bypassing the $PATH setting. To enable all libcmd
|
|
builtins do one of the following:
|
|
(a) create the directory /opt/ast/bin and the file
|
|
/opt/ast/bin/.paths with this line
|
|
BUILTIN_LIB=.
|
|
and place /opt/ast/bin before /bin and /usr/bin in $PATH
|
|
(this will affect all ksh subshells and scripts)
|
|
(b) run "builtin $( builtin | sed -e '/\//!d' -e 's,.*/,,' )"
|
|
(this will affect only the current shell)
|
|
Some scripts may run significantly faster with libcmd builtins
|
|
enabled.
|
|
$()
|
|
The AST library checks the DOSPATHVARS environment variable
|
|
for variable path values to convert to and from native windows
|
|
format when cross-executing between Cygwin and non-Cygwin
|
|
programs. The value is a space separated list of environment
|
|
variables to convert. PATH is handled by Cygwin so it is not
|
|
converted by the AST library.
|
|
$()
|
|
The ast-ksh Cygwin source package provides a bootstrap build
|
|
environment that is not suited for an edit/build/debug cycle.
|
|
If you want to explore and modify the source then you should
|
|
install the (non-Cygwinized) ast-base package which includes
|
|
AT&T nmake. With ast-base you will also be able to regenerate
|
|
the ast-ksh Cygwin source and binary packages.
