ast-ksh :PACKAGE: ksh93 libast libcmd libcoshell libsum libdll
:COVERS: ksh
:LICENSE: *.open
:CATEGORY: shells
:INDEX: ksh and support libraries
: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 impelementations,
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 list the man page on the standard error. The --???
option describes the self documenting options available to all
builtin and special commands.
$()
The stanadlone 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 astksh 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 astksh cygwin source and binary packages.
